Five-Layer Co-Extrusion Blown Film PE Film IPE Film General Composite Substrate Film Heat Seal Film
Five-Layer Co-Extruded Blown PE Film
It is produced by professional five-layer co-extruded blown molding process with a rigorous and efficient workflow: First, five independent extruders are used to melt and plasticize raw materials with different functions (such as enhancing barrier properties, improving toughness) at high temperatures; then, the five kinds of molten raw materials are accurately transported to the same composite die to realize the co-extrusion of multi-layer raw materials; after the extruded composite film material flows out of the die orifice, it is inflated by high-pressure air to form a film bubble, which is pulled upward by the traction system at the same time; during the process, the film bubble is quickly shaped by the cooling system, then flattened and trimmed, and finally wound into a flat PE film. The whole process ensures that the functional layers are tightly integrated and the performance is stable.
Core advantages are as follows:
1.Wide service fields：Can meet the professional needs of food, hygiene packaging materials and pharmaceutical packaging materials enterprises, adapting to various high-demand packaging scenarios;
2.Superior to three-layer co-extrusion：Compared with three-layer co-extrusion, the five-layer structure can distribute functional layers more accurately (such as setting independent barrier layers and reinforcement layers), greatly improving the comprehensive performance of the film such as tensile resistance, puncture resistance and gas barrier properties, and adapting to more complex packaging needs;
3.Precise and controllable feeding：The equipment feeding system is fully equipped with a weight-per-meter control system, no manual mixing is required. The automated system accurately controls the dosage of each layer of raw materials, ensuring the accuracy of raw material ratio. The production data is recorded in real time and traceable, greatly improving the batch stability of products;
4.High thickness uniformity：Equipped with an automatic air ring system, it can monitor the diameter and thickness of the film bubble in real time, automatically adjust the cooling air volume and wind speed, ensuring that the film thickness uniformity is controlled within 3~5%, and avoiding the impact of uneven thickness on subsequent processing;
5.Strict finished product quality inspection：Each batch of finished products undergoes multi-dimensional quality inspection before leaving the factory, covering physical properties (such as tensile strength, heat-sealing strength, puncture resistance), appearance (such as film surface flatness, presence of impurities or spots) and dimensional accuracy (such as width and length deviation), ensuring that every roll of film delivered meets quality standards;
6.Professional packaging and transportation：The finished products are tightly wrapped with stretch film, and then fixed and packaged with standard pallets, which effectively prevents the film from getting damp, being contaminated with dust or loose rolls due to collision during transportation, ensuring that the products are delivered to customers in good condition.
