What is the difference between PE film and composite film？
PE film refers to polyethylene film, which is the base material for soft packaging. Without PE film, packaging bags cannot be made. Composite refers to the process of making packaging bags. Usually, PE film needs to be combined with other materials to ultimately become packaging bags. Therefore, PE composite film, more importantly, refers to it as an important material in the composite process. There are many differences between PE composite film and PET protective composite film. When PE protective film and PET protective film are used on different products based on adhesive substrate, regardless of the differences between PE protective composite film and PET protective film, they are all the same protective products, increasing the service life of the products.
