In the packaging printing industry, the demand for diverse film materials is rising. Universal printing capability for the four mainstream films—PE, PET, BOPP, and CPP—has become a key to boosting production capacity and market share.
The Changhong 4-color central drum (CI) flexo printing machine fully supports universal printing on these four films. Built to solve multi-material printing pain points, it delivers one-stop high-efficiency printing with precise tension control and a highly adaptable system. No frequent debugging needed, print quality stays consistent, efficiency rises—ideal for food and daily chemical packaging needs.
It works seamlessly with stretch-prone CPP, static-prone PET, and low-ink-adhesion PE/BOPP films, breaking the "one machine for one material" limitation and becoming a core driver for enterprises to cut costs, enhance efficiency, and expand business.
I. Core Equipment Introduction
The 4 color CI flexo printing machine uses a central impression cylinder as its core, integrating four independent printing units. Adopting flexographic printing technology, it features high precision, efficiency, and adaptability, serving as a staple in plastic film printing.
Equipped with an intelligent control system, it automates the entire process from feeding, printing, and drying to rewinding. It meets both mass production efficiency and small-batch customization needs. Widely used for 4-color overprinting on plastic films, paper, and non-woven fabrics, it excels especially in PE, PET, BOPP, and CPP printing, helping enterprises improve competitiveness.

II. Adaptation Analysis of Four Mainstream Films
1. PE Film (LDPE/HDPE)
● Core Traits: Soft, tough, moisture/cold-resistant, non-toxic, compliant with food safety standards. LDPE suits food bags; HDPE is ideal for shopping bags.
● Printing Pain Points: Non-polar, poor ink adhesion, easy to stretch/deviate, ink blocking during rewinding.
● Equipment Adaptation: Corona treatment boosts surface tension. Central cylinder support and adjustable tension prevent stretching. Special inks ensure firm adhesion. Cold air cooling before rewinding eliminates ink blocking.
2. PET Film
● Core Traits: High transparency/gloss, strong mechanical strength, heat/gas-resistant, non-deformable, used in high-end food packaging.
● Printing Pain Points: High insulation causes static and dust adsorption; excessive temperature damages the film.
● Equipment Adaptation: Electrostatic eliminators resolve static issues. Precise drying temperature control avoids film damage. No complex surface treatment is needed for good ink adhesion, ensuring high-precision, high-end printing effects. Special inks meet retort packaging requirements.
3. BOPP Film
● Core Traits: Excellent transparency/gloss, airtight, moisture-resistant, tough, the most widely used printing film for composite film outer layers and labels.
● Printing Pain Points: Non-polar, low surface tension, poor ink adhesion/heat sealability, heat-induced deformation.
● Equipment Adaptation: Pre-print corona treatment enhances surface tension. Special inks boost adhesion. Central cylinder support and temperature control prevent deformation and ensure precise overprinting with vivid colors. Often compounded with PE film to avoid food contamination.
4. CPP Film
● Core Traits: Good transparency and heat sealability, even thickness, heat resistance. Regular CPP is for composite inner layers; retort-grade CPP (RCPP) is ideal for meat packaging.
● Printing Pain Points: Prone to stretching and deformation (harming overprint precision), moderate ink adhesion, defects caused by moisture.
● Equipment Adaptation: Precise tension control cuts down stretching and boosts overprint accuracy. Special inks plus post-print aging treatment lift adhesion. High-temperature inks and controlled drying let RCPP stand up to retorting without fading or peeling, and keep its heat-seal performance intact.

III. Core Equipment Characteristics
1. Stable Printing with Central Impression Cylinder
A large central impression cylinder forms the core of the 4-color CI flexo printing press, supporting printing substrates smoothly as they run around it. Full-process steady support cuts film stretching and deviation, boosting overprint precision a lot. Even for stretch-prone CPP films, we hit accurate overprinting—no ghosting, misalignment or other defects—and keep all original pattern details intact. This makes printed products meet strict food and daily chemical packaging standards, helping businesses lift product added value.
2. Wide Material Compatibility
This flexo printer features an adjustable tension control system and intelligent ink adaptation module for great versatility. It auto-adjusts printing pressure, tension and ink viscosity by the properties of PE, PET, BOPP, CPP and other films. No core component replacement is needed for multi-material printing, and it fits 10-150 micron thick films perfectly. It also works with paper, non-woven fabrics and aluminum foil, realizing one machine for multiple uses, cutting equipment investment and adapting flexibly to market order changes.
3. Efficient and Intelligent Operation and Maintenance
Advanced servo unwinding and rewinding tech ensures stable running and lower energy use for this CI flexo printing machine, with max printing speed hitting 250m/min.Its automatic ink supply system provides on-demand ink delivery, cutting ink waste and keeping color consistency—no need for frequent manual refills. The industrial-grade operation screen simplifies parameter setup, operation monitoring and fault checking, so even new operators can get the hang of the equipment quickly.
4. Stable Drying and High Yield
Independent oven and cold air cooling system combine to optimize the flexo press’s drying performance. Drying temperature auto-adjusts by ink type and film features, stopping static buildup on PET films and ink clogging on PE films. Printed films dry fast, and proper rewinding temperature keeps ink from smudging. Layered even heating in the oven also ensures consistent print quality, boosting finished product yield significantly.
5. Eco-Friendly and Durable
Water-based environmental protection ink compatibility makes this flexo printing machine eco-friendly, producing no pungent odors or harmful gas emissions during operation. This helps enterprises avoid environmental compliance risks and meet increasingly strict industry environmental requirements. Firm ink adhesion also solves the problem of poor adhesion on non-polar films like PE and BOPP, suitable for high-end packaging in food, baby products and other fields. Made of high-quality steel and precision accessories, core components pass strict quality inspections, ensuring low failure rates and long service life. Reasonable structural design facilitates later inspection, repair and maintenance—no professional operation and maintenance team required—reducing enterprise operational costs. A fault alarm system also promptly alerts operators to abnormalities, avoiding major production losses.
