High barrier shrink films are composed of a variety of materials, including polyethylene, polypropylene, nylon and PET. These materials have different properties such as softness, ductility and temperature resistance, and the right material can be selected according to the desired application.
The contractility of high barrier shrink films is achieved by introducing heat treatment in the manufacturing process. During the process of heating, the polymer chains in the film contract through the action of heat, so that the entire film shrinks and adheres to the package. This shrinkage property allows the high barrier shrink film to tightly wrap the food, thus effectively protecting the freshness and quality of the food.
