Regardless of technological development, the important factor affecting the quality of high-barrier stretch film so far is the material and production process of high-barrier stretch film, the reason why high-barrier stretch film is superior is that it has the following processes:
In order to take advantage of the properties of various polymers at the same time, multi-layer structures are often used in packaging. The multi-layer barrier stretch film process is to form a film structure from a variety of different polymers in the same process. Each polymer can chemically and physically The advantages of performance come down to one, which solves the special needs of packaging materials in the food, pharmaceutical and other industries, especially a film barrier material for the technical subject PA.EVOH.
Barrier stretch film packaging adopts physical method and adopts internationally recognized environmental protection materials for self-tapping. It is different from most of the current composite packaging. It does not use adhesives, does not contain heavy metals, and has no residual solvent problems. It is environmentally friendly and safe food. Package.
