Flexographic printing, also known as flexible relief printing, is one of the four mainstream printing processes. Its core lies in the use of elastic raised printing plates and the realization of quantitative ink supply via anilox rollers, which transfers the graphic and text information on the plates to the surface of the substrate. This process combines environmental friendliness and adaptability, being compatible with green inks such as water-based and alcohol-soluble inks, and thus meets the core demand for eco-friendly printing across various industries. The stack-type flexo printing machine is a typical equipment representative of flexographic printing technology.
Core Features of Stack-Type Flexo Printing machines
With six core advantages, the stack-type flexo printing press has become the preferred equipment in the packaging and printing sector of various industries.
Space-saving vertical design: It can adapt to various factory layouts and significantly reduce space occupation costs.
High-efficiency double-sided printing: It can synchronously complete graphic printing on both front and back sides, effectively shortening production processes and improving overall productivity.
Wide substrate compatibility: It can handle paper ranging from 20–400 gsm, plastic films (PE, PET, BOPP, CPP) from 10–150 microns, composite laminates containing 7–60 microns aluminum foil (including aluminized films and paper/film composite structures), and can also be optionally equipped with a dedicated printing module for 9–60 microns aluminum foil as required.
Standard water-based inks for eco-friendly printing: It avoids harmful residues from the source and complies with green production standards.
Cost-effective and high-return investment: It helps enterprises achieve dual improvements in production capacity and quality with lower input.
Simple and reliable operation: It reduces the rate of manual operation errors and ensures long-term stable operation of the equipment.
● Details Dispaly
When people mention stack-type flexo printing machines, most immediately think of the printing of various commodity packaging bags. In fact, this printing equipment, which integrates high efficiency, environmental friendliness, and precision, has long broken through the single packaging scenario and become a "must-have equipment" in multiple niche fields such as food and beverage, paper products, and daily chemical hygiene, playing an irreplaceable role in ensuring product quality and enhancing brand recognition.
I.Food and Beverage Flexible Packaging: Dual Guarantee of Safety and Customization
In the food and beverage industry, flexible packaging is both the primary defense for product freshness and quality and a vital brand communication carrier. For high-demand packaging like beverage labels and snack bags (e.g., potato chip bags), printing safety and aesthetics standards are exceptionally strict, and the stack-type flexo press—as a roll-to-roll web printer—serves as their core production support.
On one hand, thestack flexo press works seamlessly with food-grade eco-friendly inks, maintaining uniform pressure and controllable temperature during printing to prevent ink migration and substrate damage from the source, meeting strict food packaging hygiene requirements. For snack bags, it adapts to light-proof, moisture-proof substrates (aluminized films, BOPP) and ensures prints resist fading/ink migration even post high-temperature sterilization. For beverage plastic labels, it delivers high-quality results on shrink films and other plastic webs, with printed labels able to withstand subsequent labeling processes, cold chain transit, and shelf display for consistent packaging quality.
On the other hand, its rapid multi-color group switching enables precise reproduction of brand logos, selling points, and nutrition info, while fulfilling custom batch/spec needs. For snack bags, it vividly restores brand IPs and taste highlights in bright hues, helping products stand out on shelves.

II.Paper Bags and Food Service Paper Containers: Primary Printing Workhorse in the Eco-Protection Era
When it comes to substrate compatibility, the stack flexo printing machine can adjust printing pressure to suit a wide range of paper packaging materials—covering everything from 20gsm lightweight bag paper up to 400gsm heavy-gauge lunch box cardboard. For the tough but lightweight kraft paper used in paper bags, it prints sharp brand logos and product specifics without weakening the paper’s structural strength in the process. And for catering containers like paper cups, boxes, and bowls, it uses precise pressure control to preserve the containers’ core protective properties, while still delivering clear, high-quality print results every time.
In terms of production efficiency, the machine’s modular design lets operators run multi-color and double-sided printing at the same time, which cuts down on production timelines dramatically. Its simple, reliable operation also lowers the chance of human error during manual job changeovers, boosting overall workflow efficiency so businesses can capitalize on peak demand for both retail and catering packaging orders.

III.Tissue and Daily Chemical Hygiene Products: Balancer of Hygiene and Aesthetics, Covering Both Finished Products and Packaging Scenarios
In the field of daily chemical hygiene products such astissues, masks, and diapers, whether it is decorative printing on the product itself or information presentation on outer packaging, the requirements for hygiene and aesthetics are extremely strict. As a roll-to-roll printing device, the stack type flexo printing press is "tailor-made" for applications in this field.
Hygiene products have extremely high requirements for cleanliness in the production process. The closed ink circuit design of the stack-type flexo printing machine can effectively isolate dust pollution in the production environment, and water-based inks are used throughout the process without harmful volatilization, avoiding the risk of pollutant residues from the source. For diaper packaging, the printed graphics can firmly adhere to impermeable substrates such as PE and CPP, withstanding friction and temperature-humidity changes during warehousing and transportation. For mask outer packaging, it can accurately print key information such as brand logos and protection levels, and the ink has no odor and does not affect packaging sealing performance. In the scenario of tissue body printing, the equipment can complete delicate printing on tissue base paper webs, with water-based inks that are safe and non-irritating, and printed patterns that do not fall off when exposed to water, fully meeting the hygiene standards for maternal and infant-grade tissues.

Conclusion: Core Printing Equipment for Multi-Scenario Adaptation
With its excellent environmental performance, precise printing performance, and adaptability to multi-specification materials, the stack-type flexographic printing machine has transformed from a single packaging bag printing device into a core production equipment in fields such as food and beverage, paper products, and daily chemical hygiene. At the same time, the CI flexo printing machine—with its inherent high-speed, high-precision capabilities—works alongside the stack-type model to form a complementary product portfolio, addressing the unique printing needs of businesses across varying scales and application scenarios.
As the industry shifts toward greater green practices and production refinement, the stack flexo printing machine will keep bolstering packaging quality safeguards for enterprises in all sectors, enabling brands to boost both packaging functionality and brand value simultaneously.
