Changhong has specially designed a new upgraded version of the six color stack type flexo printing machine for plastic film printing. The key feature is the ability for efficient double-sided printing, and the functions such as the printing unit, unwinding unit and winding unit adopt servo drive technology. This advanced stacking structure enhances the accuracy of registration and production efficiency. The equipment operates stably and reliably, is easy to operate, and reduces long-term operating and maintenance costs to a certain extent. If you happen to need large-scale production of plastic film packaging, I believe this stack type flexographic printing press is your ideal choice.

● Machine Features
1.This stack type flexo printing machine increases printing speed. Combined with efficient double-sided simultaneous printing, it achieves exquisite printing on both sides of plastic film in a single pass. This not only improves production efficiency but also significantly reduces raw material loss, energy consumption, and labor costs, while completely eliminating the risk of waste caused by secondary registration errors.
2.This flexographic flexor press runs with a servo-driven unwind and rewind system, which really makes a difference when the speed goes up. The tension stays steady throughout the whole process, every section of the machine stays in sync without needing constant adjustments. In actual production, you can see the effect clearly—fine text and tiny halftone dots come out clean and sharp, and the registration stays accurate without the slipping or distortion that can happen with less stable setups.
3.Flexible with all kinds of substrates. This press works smoothly with a wide range of plastic films used for food packaging and everyday shopping bags. The ink system keeps color delivery steady and consistent, so prints look rich from start to finish. Even on non-absorbent films, it produces bright, saturated colors with a glossy finish and strong adhesion—no streaking, no fading.
4.Speed comes from smart engineering, not just running faster. Real productivity isn’t about forcing the machine to work harder—it’s about keeping every part running smoothly together. This stack flexo press is built for high-speed, with an ink supply and drying system tuned specifically for these materials. The ink goes down clean and cures quickly, which helps prevent set-off even when the press is running at full speed.

As shown in the picture below, the samples produced by the six color flexographic printing machine have vivid colors and high precision of patterns, making it a great choice for you.
Service Process
When customers reach out to us, the first thing we do is listen. Every factory has different products, materials, and production goals, so our team spends time understanding real needs. After clarifying the requirements, we recommend a suitable machine configuration and share practical experience from existing installations instead of giving generic promises. If needed, we can arrange sample test printing or an on-site visit so customers can see the equipment in action before making a decision.
Once the order is set, we wait for the final delivery date. We offer different payment choices—T/T, L/C, or staged payments for bigger projects—so customers can pick whatever is easiest for them. After that, a project manager follows the machine through production and keeps everyone updated along the way. We handle packaging and overseas shipping as an integrated, in-house capability.
We also possess the core capability to manage packaging and overseas shipping as an integrated process. This allows for granular control and end-to-end transparency, guaranteeing the safe and reliable arrival of every machine, regardless of its final destination.
When the flexo printing press arrives, our engineers usually go straight to the site. They stay until the machine is running smoothly and the operators feel confident using it—not just a quick handover and goodbye. Even after everything is up and running, we stay in contact. If something comes up, customers can reach us directly for remote troubleshooting or spare parts support. We try to deal with problems as soon as they appear, because in real production, every hour counts.
FAQ
Q1: What are the core highlights of the upgraded stack flexographic printing machine?
A1: Compared with traditional models, the new generation of stack type flexo printing press have some functions that can utilize servo drive technology. Among them, the printing unit, the servo unwinding unit and the servo winding unit are all controlled by servo motors.
Q2: What is the maximum speed?
A2: The machine can run at up to 150 m/min, and in real production the printing speed is typically maintained at a stable 120 m/min. Color registration and tension control remain very consistent, which is especially important for packaging and long-run orders.
Q3: What are the advantages of double-sided printing compared with the traditional two-step process?
A3: The biggest benefit is less waste and better use of material, so you lose less during production. Since the job is done in one pass instead of running the roll twice, it also saves a lot of time, labor, and energy. Another plus is registration and color alignment—printing both sides together makes it easier to keep everything accurate, so the final result looks cleaner and more professional, with fewer reprints.
Q4: What materials can be printed?
A4: It works with a pretty wide range of substrates. For paper, anything from 20 to 400 gsm is fine. For plastic films, it handles 10–150 microns, including PE, PET, BOPP, and CPP. In short, it covers most flexible packaging and industrial printing jobs you see in everyday production.
Q5: Is this flexo machine suitable for beginners or factories upgrading from older equipment?
A5: Yes. The operation interface is very intuitive, and the setup process is straightforward. Most operators can get familiar with the system quickly without long training. Daily maintenance is simple as well, making it a practical choice for factories looking to increase efficiency and reduce operator dependency.
