The advantages of co-extruded film and the application range are introduced
The co-extruded film is blown by a film blowing machine directly divided into multi-layer co-extrusion process.
All layers of the co-extruded film are extruded together at the same time, so there are no other non-plastic materials such as aluminum foil and paper.
The combination form of its product materials is relatively small, and the scope of application is also small, but because the winter composite layer and the layer are combined by hot melt without adhesives, the health and safety of food packaging co-extrusion film should be relatively reliable.
Difference: Co-extruded film: there is no glue between the film and the film
The separation membrane is composed of a microporous membrane or a ultrafiltration membrane as a supporting layer and covered with a dense homogeneous membrane with a thickness of only 0.1-0.25μm as a barrier layer. The amount of material passing through is greatly increased.
The wide application of coextruded film
The film produced by single-layer LDPE or LDPE blended with other resins has a single performance and cannot meet the requirements of packaging for the development of modern goods, so the co-extruded film produced by co-extruded film blowing film or co-extruded casting equipment has improved its comprehensive performance. For example, the mechanical strength, heat sealing performance, heat sealing temperature, barrier property, opening property, pollution resistance and other comprehensive properties of the film are improved, and the processing cost is reduced, and it is widely used.
For example, the hot melt film of H layer co-extrusion blowing film: PE/HM, cable film PE/EAA, low temperature hot sealing film of MLLDPE, cover film of EVA and antistatic film, smooth film. Co-extruded CPP and unmodified PP/heat sealable PP in H layer coextruded casting. Three-layer, five-layer structure of nylon co-extruded film, five-layer, seven-layer EVOH, PVDC high barrier film is also continuously developed and widely used.
In life, people often see a variety of film materials, not only plastic wrap, but also food packaging, the role is very large, people can not live without these packaging. Co-extruded film is a common film in modern life, what are its advantages? The following is an introduction to the "Introduction to the advantages of co-extruded film and its scope of use".
