PE three-layer co-extruded film: a leader in advanced packaging technology

PE three-layer co-extruded film: the leader in advanced packaging technology Polyethylene (PE) three-layer co-extruded film, as an advanced packaging material, has been widely used in many fields. The following will introduce in detail the production process of PE three-layer co-extruded film, its characteristics and its application in mattress packaging, bag making and other fields, and discuss its future development trend.

First, PE three-layer co-extruded film production process

PE three-layer co-extruded film is through three extruders will be different functions of the PE material melting and plasticizing, and at the same time from a common die extrusion and the film produced. This production process makes the three-layer film can be extruded in the same time, the middle layer can be added to functional additives, such as oxygen barrier agent, moisture-proof agent, etc., so as to form a waterproof, freshness, oxygen barrier and other functions of the packaging film.

Second, the characteristics of PE three-layer co-extruded film

1、Superior waterproof performance: PE three-layer co-extruded film has good waterproof performance, which can effectively prevent water from entering the packaging interior and protect the internal items from moisture.

2, good barrier: by adding specific additives, PE three-layer co-extruded film can effectively isolate oxygen, ultraviolet light and other external factors, to protect the quality and stability of the internal goods.

3, safety and environmental protection: PE is a halogen-free environmentally friendly materials, non-toxic and tasteless, in line with relevant health standards, can be used safely.

4, high transparency: PE three-layer co-extruded film has a high degree of transparency, can show the beauty of the products inside the package, enhance the consumer's desire to buy.

5, good printing effect: due to the high surface polarity of PE three-layer co-extruded film, printing ink adhesion, making the appearance of the packaging more beautiful.

6, excellent physical properties: PE three-layer co-extruded film has a strong tensile strength, high degree of puncture resistance, non-slip, heat shrinkage and other characteristics, making it more advantageous in packaging applications.
