Precision, High Speed And Environmental Friendliness: Stacking Flexo Presses Reshaping The Modern Printing Landscape

I. Introduction: A wave of equipment innovation in Printing industry's transformation
1.1 Industry Background: Dual drivers of market expansion and Demand Upgrading.
The packaging printing industry is experiencing a dual leap of scale and quality driven by the expanding global consumer market and the deep readjustment of the industrial structure. According to the "2024 China Packaging and Printing Industry Development Report 2024 released by the China Printing and Equipment Industry Association, China's packaging and printing industry market size exceeded 1.2 trillion yuan in 2023, growing 5.8% year-on-year. Among them, food packaging, e-commerce logistics packaging and other sub-areas of growth of more than 8%. The growth trend is driven by a shift in demand driven by consumption upgrading and the rise of e-commerce, whereconsumers are increasingly demanding personalized and aesthetically pleasing packaging. the "small-batch, multi-batch, fast-delivery" model has completely defied the traditional printing industry's logic of large-scale production.
At the same time, tighter regulations in downstream industries have further contributed to quality upgrading and environmental transformation in the printing industry. In sensitive areas such as food and medicine, the EU Regulation (EU EU) No. 10/2011 specifies the limits of harmful substances in printing materials, and China's "General Safety Requirements for the Safety of Printed Materials and Food Contact Products also set stricter standards for packaging safety. Due to the pressure from both market and regulatory ends, the performance shortcomings of traditional printing equipment are becoming more and more prominent, and the industry needs new printing equipment with precision, efficiency and environmental protection.
1.2 Industry pain points: Performance Bottlenecks in traditional Printing Equipment.
For a long time, the packaging printing industry mainly depends on gravure printing, letterpress and ordinary flexographic printing machines, but all three technologies have insurmountable performance bottlenecks. In the "White Paper on Technological Development of Flexographic Printing Equipment Industry (2024), the National Centre for Quality Supervision and Inspection of Printing Machines (NCCQIM) noted that while gravure printing machines can achieve high quality printing, there are issues such as high seam production costs, large VOCs emissions from solvent based inks and large equipment footprint. Single equipment installation space generally requires more than 100 square meters, order replacement time up to 2-3 hours, difficult to accommodate the requirements of small orders.
The embossing machine is limited by the structure of the plate and is not suitable for flexible materials such as film and non-woven cloth. Their printing speed is generally less than 150 metres per minute, which isnot sufficient for mass production. Even ordinary flexographic printing machines, whose market share is increasing year by year, faces the challenge of balancing accuracy and productivity. In the traditional horizontal unit layout, tension fluctuations between printing units tends to lead to overprinting deviation. The an overprinting precision most devices can only be maintained at about 0.1 mm, the speed of multi-color printing loss is very large, restricting the development of the high-end packaging market.
1.3 Core positioning: Breakthrough value Stacked Flexographic Printing Machines
Stacked flexographic printing machines provides a systematic solution to the pain points of traditional equipment through the technological innovation of ``stereo layout + intelligent control ''. Unlike the traditional horizontal layout, it adopts vertical overprint unit design, combines independent servo drive and intelligent tension control technology, greatly reduces the footprint and simultaneously improves accuracy and productivity. In its Flexible Printing Industry Forecast 2028, Smithers Pira, an international printing industry research firm, predicts that the global laminated stacked flexographic printing machines penetration rate will reach 25%% by 2026, up from 12% in 2023, and even exceed 40% in high-end segments such as food packaging and smart labelling.
This growth is due not only to the multiple optimization of devices in terms of space, efficiency and accuracy, but also to their perfect fit with the development trends of "greening, intelligently personalizing" the printing industry. As a key device connecting traditional printing with modern intelligent manufacturing, stack printing machines are driving the industry's shift from scale-driven to value-driven, reshaping the global packaging printing industry.
ii. Structural Innovation: 3D Layout to Solve Space and Efficiency Dilemmas
2.1 Technology Core: from horizontal to Vertical Stacking
The revolutionary breakthrough of stacked flexographic printing machines is first reflected in the innovation of printing unit layout. Traditional unit-type flexographic printing machines is arranged horizontally, with each unit distributed in sequence along the direction of movement of paper or film. Equipment length is generally 15-20 meters, occupies a large area, the workshop space aspect ratio requirements are strict. Instead, stacked flexographic printing machines stack multiple printing units vertically, creating a "tower" structure on the rack. By turning the drum and guiding the base plate to travel vertically, the length of the equipment is reduced to 5-8 meters, covering only 1/3-1 / 2 of the floor area of traditional equipment.
This kind of three-dimensional layout is not simple space compression, but the deep fusion with core technology. According to Bosch Group Bobst Group "Technical Manual for Structural Optimization and Performance Improvement of Stacked Flexographic Printing Machines, the company's overprint machine adopts an independent servo drive system combined with high-precision tension closed-loop control to realize the synchronous operation and independent adjustment of each printing unit, completely solving the speed lag caused by the long transmission chain in the traditional horizontal layout. The modular design of laminated presses has more advantages than satellite flexo printing machines --each unit can be detached and replaced independently, supporting flexible configurations from two to 10 colors, with a plate change time of more than 40% less than satellite equipment.
In "the"Study on the Effects of Flexographic Printing Machine Layout Design on Production Efficiency, "the Heidelberg Printing Equipment Research and Development Center confirmed through comparative experiments that the the equipment vibration amplitude of stacked flexible printing machines is only 15% of that of horizontal units under the same printing width (100 mm) and at the same printing speed (300 m per minute), providing a structural basis for achieving high precision printing.
2.2 Practical benefits: Dual Breakthroughs in space occupancy and Production Continuity
The spatial advantages brought about by the three-dimensional layout are directly translated into the improvement of the return on investment of enterprises. For small and medium-sized printing enterprises, stacking equipment can double the production capacity in the original workshop space without increasing the input of workshop expansion costs; for large production bases, the increase in space utilization means a significant increase in output value per unit area. In the third issue of Printing Technology in 2024, "Structural Advantages and Practice of Stacked Flexographic Printing Machines," the introduction of an 8-color stacked flexographic printing machine in food packaging enterprises was reduced the floor area from 120 square meters (horizontal equipment) to 45 square meters, with a 220% increase in unit capacity.
More importantly, the combination of structural innovation and automation technology has led to breakthroughs in production continuity. Traditional printing equipment needs to be plate replacement off during the process of switching and parameter adjustment, the time of a single switch is usually 40-60 minutes. the stacked flexographic printing machine is equipped with a pre-overprint memory system, automatic plate washing device and a non-intermittent plate changing mechanism, which can reduce the plate changing time to less than 10 minutes. Data from the case enterprises mentioned above show that after the introduction of yard stacking equipment, the effective operation rate of the equipment increased from 65 per cent to 88 per cent, the annual production capacity increased by 15 million copies and the cost of single-page printing decreased by 12%.
In terms of production stability, stacking reduces the trip of substrates and reduces the risk of material stretching and deformation. The application practice of a daily chemical packaging enterprise shows that when PET films are printed in stacked flexible printing press, the material tensile rate decreases from 2.5% (traditional equipment) to 0.8%, and the waste rate from 3.2% to 0.9%, reducing material loss by more than 800,000 yuan per year.
III. Precision Leap: Intelligent Closed-loop Control for Micron-Level Overprinting
3.1 Control System: Collaborative Mechanisms for Visual Detection + Algorithm Compensation + Servo Execution
If the three-dimensional layout is the "skeleton"of stacked flexible the stacked flexographic printing machine, then the intelligent closed-loop control system is the ``nerve center" of stacked flexible printing press, which is the core guarantee to achieve micron-level overprinting precision. This system establishes the wholelink control mechanism of visual compensation-servo execution, which completely changes the extensive and precision control mode of traditional printing which relies on manual adjustment.
High-definition CCD visual inspection technology is a precisely precision control "eye." Kodak Flexographic Solutions Division, in its Guide to Intelligent Overprinting Technology in Packaging Printing, said its accompanying visual inspection system features a 20-megapixel CCD camera coupled with LED high-frequency strobe light for real-time photography of printed patterns. Image image acquisition speed reach 1000 frames per second and can capture an overprint bias of 0.01 mm. Compared with traditional photoelectric detection, CCD visual inspection is independent of pattern color and substrate and can be adapted to a wide range of materials, from paper to metal foil, with 99.9 99.9% accuracy.
Intelligent algorithms are precisely precision control "brain." The adaptive PID algorithm proposed in Beijing Graphics and Communications Institute's 2024 master's thesis "Research on Flexographic Printing Overprint Precision Control Based on Machine Vision" can analyze the deviation data transmitted by vision inspection system in real time. It can not only adjust the servo motor parameters according to current deviation, but also forecast deviation trend through historical data and make advance compensation adjustment. Experimental data show that the adjustment response time of overprinting deviation is reduced from 0.5 seconds to 0.1 seconds, and overprint error is reduced by 60%.
The high-precision servo execution system is precisely controlled precision controlhands and feet ''. Siemens Industrial Automation states in the "Precision Control Solution of Servo Drive System in Printing Equipment that the 1FK7 series servo motor has a positioning accuracy of 0.001 degrees. Combined with a planetary gear reducer, the micro angle adjustment of printing roller can be realized, and adjustment accuracy is 0.1 micron. Each printing unit The independent servo drive, can carry on the monochrome overprint adjustment independently, avoids the traditional equipment ``one-machine hyperactivity"adjustment problem.
3.2 Precision Performance: Achieving High-end Printing Standards and Value Transformation
Adopting the intelligent closed loop control system of multi-technology cooperation, the quality of overprinting accuracy of stacked flexographic printing machines has been improved. Measured data from the above-mentioned master's thesis of Beijing Institute of Graphic Communication show that the accuracy of vertical overprint of the stacked flexographic printing machine is stable at ±0.02 mm and transverse overprint is stable at ± ± 0.03 mm under the condition of printing speed of 300 m / ± 0.1 mm and BOPP film substrate, which is much higher than the precision level of ordinary flexographic printing machines and even exceeds the standard of gravure printing machines.
This high precision performance effectively solves the problem of overprinting deviation caused by material stretching and equipment vibration in traditional printing. In film printing, temperature change and tension fluctuations tend to cause the material to be slightly stretched, and it is difficult for traditional equipment to compensate in real time. However, the stacked flexographic printing machine can visually capture the pattern offset due to material stretching and complete the servo adjustment in 0.1 seconds, keeping deviations within permitted limits. The application examples of cigarette pack printing enterprises show that when using a stacked flexographic printing machine to print anti-counterfeit cigarette packs, the accuracy of overprinting is stable at ±0.03 mm, which fully meets the high precision requirements of cigarette pack printing, and the waste rate drops from 1.8% (traditional gravure printing) to 0.5%.
The improvement of accuracy not only reduces the waste rate, but also expands the application space stacked flexographic printing machines in the high-end market. In the printing of QR code, traceability code and other small patterns, stacking equipment can achieve 0.1 mm line clear printing, food traceability, drug regulation and other areas of precision printing needs. Pharmaceutical packaging packaging enterprise a stacked flexographic printing machine, successfully undertook high-precision pharmaceutical traceability code printing orders, the value added of products increased by 30%, new annual sales more than 5 million yuan.
IV. INTRODUCTION Production Capacity Breakthrough: Fast order changes, Synchronous Printing Activate New Momentum
4.1 Efficiency Core: Systematic Innovation in Rapid Order Change Technologies
Driven by e-commerce economy and personalized consumption, printing orders are characterized by ``small batch production, multi-batch production, short-cycle production '', and order change efficiency becomes the key factor affecting the production capacity of enterprises. Stacked flexible flexographic printing machines through the system innovation of order change process, set up a process from prepress preparation to production switch efficiency mechanism, completely changed the traditional printing ``stop and change order"inefficient mode.
Shaftless transmission technology is the core support to realize rapid order change. In "Advantages of Axle Shaftless Transmission Technology Flexible Flexographic Printing" Manroland Printing Equipment Company noted that traditional mechanical transmission systems require repeated calibration of each unit when orders change due to gear backlash and transmission lag. However, error accumulation accumulation of mechanical transmission can be eliminated by means of independent servo motors which drives the printing roller directly. In the process of order change, it is only through the control system to modify the parameters that the synchronized adjustment of the units can be achieved, reducing the parameter setting time by 70%.
The deep integration of digital workflow further improves the efficiency of order change. The CIP3/CIP4 data interface proposed by Esko Packaging Solutions in "Optimization of Digital Workflow and Flexographic Printing Machine Order" enables direct data transfer between preprint design documents and printing equipment and automatically feeds plate size, overprint parameters and ink consumption into the printing control system, avoiding errors and time consuming input caused by manual parameters. Parameter setting time for a single order is reduced from 15 minutes to 3 minutes with the CIP4 the CIP4 digital workflow according to data from a consumer goods fast-food packaging enterprise.
Auxiliary automation devices completes the final step, and orders change quickly. The 2024 edition of China Packaging, No. 5, "Practice and Exploration of Rapid Order Change Technology for Stacked Flexographic Printing Machines," explains that stack-mounted automatic loading and unloading equipment can automatic grabbing and install a robotic arm, reducing the time it takes to replace a veneer from 5 minutes (manual operation) to 1 minute. The pre-overprint memory system can store overprint parameters of different orders without recalibrating, reducing the time for order change overprint calibration time from 20 minutes to 5 minutes. Overall, stacked flexographic printing machines can be replaced in less than 10 minutes on a single order, which is more than 75% more efficient than conventional devices.
4.2 Production Capacity leap: increase in synchronous printing and Equipment Utilization
Fast order modification technology solves the efficiency loss in ``production gap '', while multi-color synchronous printing technology increases the speed limit of ``effective production ''. The 3-D layout of stacked flexible stacked flexographic printing machines enables all printing units to work in parallel in a vertical direction. The substrate can be printed in multicolor with only one pass, avoiding the loss of speed caused by multi-material flips in the traditional horizontal layout. According to the China Packaging Federation's Productivity Assessment Report for Packaging Printing Equipment 2024, mainstream six-color stacked flexo printers can print up to 400 meters per minute, more than 30% faster than comparable horizontal units.
Even with multicolor printing, the speed advantage of stacking models is still evident. Traditional horizontal unit devices print orders in more than eight colors at a reduced speed to ensure overprint accuracy, typically only up to 200 to250 meters per minute. However, with independent servo drive and intelligent control, flexographic printing machines can still achieve speeds of up to 350 meters per minute. Ryobi Printing Machinery records in "Case Study of Production Capacity Advantages of Stacked Flexographic Printing Machines in Mass Packaging Production" that a beverage packaging enterprise uses an 8-color stacked flexographic printing machine to produce PET bottle labels with a daily production capacity of 1.2 million copies, 50% higher than the original horizontal single machine equipment, successfully meeting the peak demand of beverage enterprise.
The combination of rapid order change and high-speed printing has achieved a qualitative leap in the utilization of stacked flexible printing press equipment. Because of the long order replacement time, the utilization rate of traditional printing equipment is generally between 60 and 70 per cent, while stacked printing equipment can be increased to 85 to 90 per cent. Statistics from one packaging printing enterprise show that while the cost of purchasing a single stacked flexographic printing machine is 20% higher than conventional equipment, the investment payback period is only 1.5 years, a year shorter than for conventional equipment, due to increased capacity and lower waste rates.
V. Green empowerment: low-carbon technologies in line with global environmental trends
5.1 Pollution Reduction: control of Pollutant Emissions at source
Against the background of the global "dual carbon" goals and increasingly stringent environmental regulations, green production has become the bottom line and a competitive advantage for printing enterprises. Stacked flexographic printing machines has been integrated into the environmental protection concept from the beginning of process design, and has become the core equipment of the green transformation of printing industry through technological innovation to realize source control of pollutant emissions.
The wide application of environmental protection ink is the key to pollution reduction. In the Flexible Printing Environmental Process Standards and Implementation Guide, the National Environmental Engineering Technology Center for Pollution Prevention in the Printing Industry states that the flexible version used in the overprinter is compatible with environmental ink and can be compatible with a wide range of low volatile organic matter inks such as hydro ink and UV-LED curing ink. Data provided by the BASF Ink and Pigment Division in the Benefits Analysis of the Use of Environmentally Friendly Inks in Flexographic Printing show that the emissions of volatile organic compounds from hydro-based inks are only 1/10 of those of traditional solvent inks, reducing the emissions of volatile organic compounds by about 8 kg per 10,000 square metres of printing.
The application of UV-LED curing technology has further improved environmental performance. Compared with traditional UV curing technology, the UV-LED curing system does not require preheating, reduces energy consumption by more than 60% and does not produce harmful gases such as ozone. Philips UV-LED Division said in an article titled "Energy Saving Applications of UV-LED Curing Technology in Flexographic Printing" that the company's UV-LED Curing Module can be used in combination with stacked flexographic printing machines press to achieve instant curing, not only increasing printing speed, but also avoiding pollution problems caused by solvent volatilization. Measured data by one packaging enterprise show that the VOCs emission concentration (VOE) of UV-LED curing laminated flexible printing presses is only 15 mg/m3, well below the 100 mg/m3 limit set by the Printing Industry Air Pollution Emission Standards (GB41616-2022).
Solvent-free cleaning technology solves the problem of wastewater pollution problem in traditional printing. Stacked flexible stacked flexographic printing machines equipped with a fully automatic plate washing system using solvent-free cleaning agents, combined with ultrasonic cleaning technology, can achieve efficient plate cleaning. No wastewater is produced in the cleaning process, and the recovery rate of cleaning agent is more than 95%%. With this technology, food packaging enterprises reduce printing wastewater discharge by 1,200 tons per year and the cost of detergent consumption by 40%.
5.2 Resource conservation: Dual Optimization of energy consumption and Material Utilization
The green value of stacked flexible stacked flexographic printing machines is not only in pollution reduction, but also in increasing resource utilization efficiency. Through dual optimization of energy consumption and materials, help enterprises reduce production costs and achieve low-carbon development.
In terms of energy consumption control, the combination of 3D layout and intelligent driving technology greatly reduces the unit energy consumption of the device. At the same production capacity (300 meters per minute), the unit energy consumption output energy consumption a laminated flexo press is 0.8 0.8 kWh only a third of that of a traditional gravure press and 40 40% than that of a regular flexo press, according to the Technology Evaluation of Printing Equipment (2024) published by the the China Energy Conservation Association. The advantages are as follows: the independent servo drive system can dynamically adjust energy consumption according to printing speed, avoiding energy loss of traditional mechanical transmission; the UV-LED curing system replaces the high-energy-consuming mercury lamp curing system; optimization of equipment structure reduces friction loss of moving parts and further reduces energy consumption.
In the field of material utilization, high-precision printing technology effectively reduces material waste. The micron-level overprinting precision of stacked flexible printing press can control the positioning error of printing pattern to a small extent and avoid waste caused by inaccurate overprinting. Data from a film packaging enterprise show that with the stacked flexographic printing machine, the material utilization rate increases from 88% to 97%, reducing film loss by 30 tons per year and saving material cost by 1.2 million yuan.
In addition, the modular design of stacked flexible stacked flexographic printing machines reduces equipment maintenance costs and extends the service life of the equipment. The independent design of each printing unit facilitates fault diagnosis and component replacement, with an average time between equipment failures of more than 800 hours, 50% more than traditional equipment; standardized design of vulnerable parts reduces the procurement cost of spare parts and the total life-cycle cost of equipment by 25%.
5.3 Policy Alignment: Compliance with Environmental Laws and Market Value Enhancement
The green characteristics of stacked flexible stacked flexographic printing machines make it fully meet the requirements of global environmental policy and help enterprises avoid policy risks and improve product competitiveness. From 2026, the European Union will strictly calculate the carbon carbon footprint imported packaged products, and carbon-intensive printing products will face additional carbon carbon tariffs the European EU's Directorate General for the Environment said in its "Guidelines the" Impact and Compliance of Chemical Oxygen Demand on the Packaging Printing Industry. " Stacked flexo presses produce packaging products that have a 30% lower carbon footprint than traditional processes because of their low energy consumption and low pollutant emissions and can effectively address barriers to trade barriers created by the CBAM policy.
In the domestic market, laminated flexographic printing machines in line with the National Green Printing Development Policy and can be supported by a number of policies. The China Printing Technology Association lists stacked flexographic printing machines as "recommended green printing equipment" in its Green Printing Equipment Selection Standard (2024 edition). Enterprises using this equipment can obtain green printing certification bonus points, priority to undertake government procurement orders. In addition, some regions also provide financial subsidies to enterprises that introduce green printing equipment, further reducing the cost of upgrading equipment.
The increase in market value from green production is even more significant. With the improvement of consumers' environmental awareness, green packaging has become an important means for brand enterprises to enhance their market image. stacked flexographic printing machines produces eco-friendly packaging that conforms to the "low carbon, safe and sustainable" consumption concept and is favored by industry leaders such as food and consumer chemicals. According to one daily chemical brand, stacked flexographic printing machines have 25% more market recognition for environmentally friendly packaging products than traditional packaging, with a product premium space of 10% -15%.
VI. INTRODUCTION Scenario Expansion: Diversified Adaptability Expands Industrial Application Boundary
6.1 Food and Pharmaceutical Packaging: Safety and Compliance as Core

In the field of food packaging, the application of eco-friendly ink is the key to meet safety standards. In the Interpretation of Safety Standards for Food Exposure Printing Materials (2024), the State Food and Drug Administration explicitly requires that the movement of hazardous substances in food packaging printing materials must be less than 0.01 mg/dm2. Sun Chemical's food-grade water-based inks, introduced in the Food Packaging Flexographic Printing Environmental Ink Application Guide, are internationally certified by the FDA and EU 10 / 2011, and transport of harmful substances is only one-fifth of the standard limit. When stacked flexible stacked flexographic printing machines is used, food packaging can be printed safely. With the adoption of this solution, an infant auxiliary food packaging enterprise has successfully entered the high-end auxiliary food market in Europe through rigorous testing in the EU market.
In the field of drug packaging, high-precision traceability code printing is a core requirement. Drug regulators require clear and accurate the traceability code for each cartridge of drugs to enable the whole-life cycle traceability. The micron-level overprinting precision of stacked flexible printing machine can achieve high precision printing of traceability codes such as QR code and bar code, and the trace code recognition rate reaches 99.99%. The application case of a pharmaceutical enterprise shows that after using a stacked flexographic printing machine to print drug packaging boxes, the pass rate of retro-code printing increased from 98.5% (traditional equipment) to 99.98%, which effectively meets the requirements of pharmaceutical regulation and avoids the risk of product recall due to blurred traceability codes.
6.2 Daily Chemistry and FMCG Packaging: Double Satisfaction with Color and Efficiency

Stacked flexible flexographic printing machines has become the equipment of choice in the fast printed the FMCG industry by the color management technology and the ability to change orders quickly, thus achieving the dual satisfaction of color and efficiency.
High accuracy of color reproduction is the outstanding advantage of stacked flexographic printing machines. The packaging of daily chemical products usually adopts bright and complicated design, which requires high color saturation and reproducibility. L'Oreal Packaging Supply Chain the FMCG Packaging PrintingColor Management and Equipment Selection Criteria states that the color reproduction error (ΔE value) of FMCG packaging packaging must be controlled to within 1.5. The high-precision color control system with stacked flexible stacked flexographic printing machines enables real-time detection of printed colors by a spectrophotometer and, in combination with intelligent ink adjustment systems, the ΔE value can be stably controlled up to 1.0 with a color reproduction rate more than 98%%, fully satisfying the packaging needs of high-end consumer chemicals. According to one skin care brand, superprinted flexo print packaging packaging products 30 30% color consistency than traditional print, with consumers 22% per cent more satisfied with the appearance of 22 packaging.
The ability of rapid order change is fully adapted to the "multi-batch, small-batch" production characteristics of fast consumer goods. The FMCG industry seasonal promotional activities, frequent packaging designs requires to be changed, traditional printing equipment order replacement time, difficult to meet the demand. The quick order change capability of stacked flexible stacked flexographic printing machines (in 10 minutes) enables quick switching of different batch orders. During the Double 11 promotion, the shampoo shampoo brand able to quickly produce five packaging packaging designs laminators, completing orders for 120,000 cases a day, 40 40% than traditional devices, successfully snapping up the peak season market opportunity, according to DuPont Packaging's Films & Flexible Flexographic Printing Adaptability Study.
6.3 Smart Labels and Functional Packaging: Exploring New Growth Points

In the field of intelligent labels, stacked flexographic printing machines can achieve integrated production of RFID labels. Traditional RFID label production requires printing, chip packaging, composite, etc., which is inefficient and costly. The stacked flexographic printing machines can be integrated with RFID chip implantation and packaging units through modular upgrading to achieve the integrated production of label pattern printing and RFID function. In its Smart Label Printing Technology Development Report 2024, the International Label Association (FINAT) predicts a 30% decline in integrally produced RFID labels costs and a market size of over $20 billion by 2027. The stacked flexible print RFID production line, developed in partnership with Bobst, can produce 100,000 RFID labels per hour, which is 60% more efficient than traditional production lines, according to TE Connectivity in the Integrated RFID Label Printing Packaging Equipment Needs Analysis.
In the field of functional packaging, stackable flexographic printing machines can realize special technology such as temperature sensing, anti-counterfeiting and preservation of freshness. "Application of Stacked Flexographic Printing Machines in Functional Labeling Production" in the third issue of Labeling Technology, 2024, documents the use of stacked flexible printing machines for the production of temperature sensing labels by a raw e-commerce enterprise.

7.3 Revelations to Business: Strategic Necessity for Equipment Upgrading
During the critical period of printing industry transformation, the introduction stacked flexographic printing machines is no longer a simple equipment update, but a strategic choice for enterprises to improve their core competitiveness. The Industrial Department of the National Development and Reform Commission (NDRC), in its "the"Interpretation of the Green Upgrading Action Plan for the Packaging Printing Industry (2024-2026), "clearly stated that printing enterprises should be promoted to accelerate the upgrading of green and intelligent equipment. By 2026, the green, smart printing equipment market penetration rate will reach more than 50%. This policy orientation means that enterprises that still rely on traditional printing equipment will face increasing policy and market competition pressures.
For printing enterprises, the strategic importance of equipment upgrading lies in several ways: from a competitive perspective, the high accuracy, efficiency, and environmental attributes of stacked flexographic printing machines can help enterprises take high-end orders and escape low price competition; from a policy compliance perspective, the green process of laminated flexo printing machines can help companies meet increasingly stringent environmental standards and avoid policy risks; and from a long-term perspective, the intelligence and integration of laminated flexo printing machines can help companies align with future industry development and build sustainable competitive advantages.
In the face of this trend, printing enterprises should formulate scientific equipment upgrading plan according to their own business characteristics: small and medium-sized stack flexographic printing machines can be introduced to focus on the high-end packaging market in the region; large enterprises should build intelligent production lines with stacked flexographic printing machines as the core, and build full-chain service capability. Printing enterprises can not only achieve their own high-quality development through equipment upgrading, but also promote the entire printing industry to green, intelligent, high-endization transformation, providing solid support for the transformation and development of packaging industry.
