PE CI Flexo Press

PE CI Flexo Press refers to a central impression flexographic press specifically designed for printing on PE (Polyethylene) films.

What is a PE CI Flexo Press?

A PE CI Flexo Press is a flexographic printing device whose core feature is its central impression (CI) structure. In this structure, the printing material (PE film) is pressed tightly against a central impression cylinder and passes through multi-color flexographic printing cylinders, achieving high-speed, multi-color, and high-precision printing.

Main Applications

Packaging Film Printing: Printing on PE film products such as food packaging bags, express delivery bags, and shopping bags.

Label Printing: Suitable for scenarios requiring flexible film labels.

Advertising or Promotional Materials: Printing promotional materials made of PE film.

In short, the PE CI Flexo Press is primarily used in the production of PE films requiring high-precision, multi-color, and high-speed printing.

Comparison with other printing presses

Core Product Advantages

1. Targeted Optimization for PE Film, Solving Core Printing Pain Points
The press is specially calibrated for the physical characteristics of PE film, such as poor ink adhesion, easy stretching, and low surface free energy. Equipped with a large-diameter central impression drum, the core component of CI flexo technology, it ensures uniform web tension and zero substrate shift during the printing process, effectively avoiding film stretching and wrinkling, and achieving ±0.1mm registration accuracy even on ultra-thin PE films (12 microns). The closed inking unit with chambered doctor blades and laser-engraved ceramic anilox rollers ensures uniform ink feeding, minimizes dot gain, and enhances ink transfer efficiency on PE film surfaces. It is matched with HP’s professional PE-specific inks, which can firmly adhere to the PE film surface, preventing ink peeling, fading, and smudging, and ensuring clear patterns and stable colors from the first print to the last batch.

2. High Efficiency and Low Waste, Reducing Production Costs
Adopting a high-performance gearless servo drive system, the press realizes stable high-speed operation, with a maximum printing speed of up to 80 meters per minute in multi-color mode, which is far higher than the industry average, and can efficiently complete medium-to-long production runs. The fast-sleeve change design and automatic pre-registration function significantly shorten the make-ready time, reducing the time cost of job switching. The upgraded automatic tension control system with loop self-detection is specially adjusted for the elasticity of PE film, effectively reducing film tearing and edge curling, and reducing the substrate waste rate to less than 1.5%, which is much lower than the 5-10% waste rate of traditional printing methods. In addition, the intelligent ink supply system reduces ink waste, further reducing production costs for converters.

3. Outstanding Environmental Advantages, Conforming to Global Green Trends
Adhering to HP’s sustainable printing concept of “reduce, reuse, renew”, the press highlights excellent environmental performance in all aspects. It is compatible with PE-specific eco-friendly water-based inks that are non-toxic, low-VOC, and compliant with FDA, ROHS, and SGS certifications, which are odorless and pollution-free, meeting food packaging safety requirements. These inks have fast drying speed, high wear resistance, and good water resistance, and can be directly used for food packaging printing. At the same time, the press supports recyclable PE film substrates, realizing green printing throughout the whole process, helping converters reduce carbon emissions and achieve environmental transformation. The energy-saving servo drive system and efficient ventilation and drying design further reduce energy consumption, reflecting HP’s commitment to sustainable development.

4. Intelligent Operation and Versatile Compatibility, Improving Operational Efficiency
Designed for ease of use, the press is equipped with a user-friendly PLC touch screen, allowing operators to adjust parameters such as tension, ink amount, and drying temperature according to different types of PE film (including LDPE, HDPE, CPP), with simple operation and low training costs. It supports HP PrintOS X cloud connectivity, enabling remote monitoring, workflow management, and data analysis, helping enterprises optimize production scheduling and reduce downtime. The press has strong substrate compatibility, supporting various PE films and PE laminates with thickness ranging from 12 to 200 microns, and can flexibly configure 4-8 color units according to actual needs, reproducing up to 97% of PANTONE colors, realizing rich color expression and meeting the diverse printing needs of different products.
