China Suppliers Five-Layer Co-Extrusion Blown PE Film Factory for Versatile Packaging Solutions
Five-Layer Co-Extruded Blown PE Film
Can meet the professional needs of food, hygiene packaging materials and pharmaceutical packaging materials enterprises, adapting to various high-demand packaging scenarios.
Compared with three-layer co-extrusion, the five-layer structure can distribute functional layers more accurately, greatly improving tensile resistance, puncture resistance, and gas barrier properties.
The feeding system is fully equipped with a weight-per-meter control system. It accurately controls raw material ratios automatically, recording real-time and traceable production data.
Equipped with an automatic air ring system to monitor film bubble diameter and thickness in real time, keeping thickness uniformity deviation controlled tightly within 3~5%.
Every batch undergoes multi-dimensional testing before shipment, checking physical strength, appearance flatness, absence of impurities, and precise dimensions.
Finished products are wrapped tightly with stretch film and secured onto standard pallets to prevent moisture, dust, or damage during transportation.
Frequently Asked Questions (FAQ)
It is a high-performance polyethylene film manufactured using five independent extruders. This process allows different functional raw materials to be combined into a single, tightly integrated structure to optimize strength, barrier properties, and durability.
The five-layer structure allows for more precise distribution of specialized functional layers (such as dedicated barrier and reinforcement layers). This significantly enhances the film's tensile strength, puncture resistance, and gas barrier performance compared to standard three-layer films.
This film is highly suited for industries requiring strict packaging standards, including food packaging, hygiene products, and pharmaceutical packaging applications.
We utilize an automatic air ring system that constantly measures the film bubble's thickness and diameter. By automatically adjusting the cooling wind speed and volume, the system maintains thickness variations within a tight 3~5% margin.
Every batch of film undergoes thorough testing for physical properties (including tensile, puncture, and heat-sealing strength), visual defects (impurities or spots), and dimensional accuracy (width and length tolerances) to ensure top quality.
