Separate Two Color Flexo Printing Machine

1. High Efficiency for Enhanced Productivity​

Flexo printing machines feature advanced sleeve-type plate rollers and rapid plate-changing technology, reducing single plate replacement time to within 15 minutes—an over 40% efficiency improvement compared to traditional printing equipment. Xinke's independently developed intelligent tension control system, combined with servo motor drive technology, balances printing speed and registration accuracy seamlessly. With a maximum printing speed of 300 meters per minute, it meets the demands of large-scale order fulfillment. For paper bag manufacturers, this efficiency means the ability to handle more orders during peak seasons and minimize equipment idle costs through flexible scheduling in off-seasons, driving both productivity and profitability.​

2. Green & Sustainable: Aligning with Industry Trends​

As the "Double Carbon" goal progresses and consumer environmental awareness grows, the green transformation of the packaging and printing industry is imperative. Flexo printing machines use water-based and UV inks that are free of volatile organic compounds (VOCs), eliminating pollution at the source. Xinke's equipment is equipped with advanced ink recycling systems and waste gas treatment devices, achieving an ink utilization rate of over 95% and emissions compliant with GB 38507-2020 Limits of Volatile Organic Compounds (VOCs) Content in Inks. Choosing flexo printing machines is not only a response to policy calls but also an investment in building a green brand image—especially vital for industries with strict packaging requirements like food and pharmaceuticals.​

3. Superior Quality for Exquisite Printing​

The embossed plate characteristics of flexo printing enable delicate graphic presentation on various materials, including paper, film, and non-woven fabrics. Xinke's flexo printing machines are equipped with high-resolution laser engraving platemaking systems and automatic registration detection, controlling registration errors within ±0.05 mm. This ensures precise reproduction of design，from gradient color transitions to fine text lines. Notably, addressing common issues like wrinkles and uneven ink in paper bag printing, our machines feature intelligent deviation correction and adaptive pressure adjustment, ensuring every batch meets export-grade quality standards and helping clients establish a reputation for excellence in high-end markets.​

4. Flexible Adaptability for Diverse Needs​

The modern packaging market trends toward small batches, multi-variety, and personalized production—and flexo printing machines excel in meeting these demands. Supporting a printing width range of 100–1500 mm, they effortlessly switch between mini shopping bags and large industrial packaging. Through modular design, Xinke's machines can integrate post-processing units such as varnishing, lamination, and die-cutting, forming a "printing + processing" one-stop production line. For the customized needs prevalent in e-commerce packaging, the equipment supports rapid pattern import and parameter settings, enabling "one-click switching" between orders and gaining a competitive edge in the personalized market.​
