What are the characteristics of heat shrinkable film?

The product characteristics of PE heat shrinkable film manufacturers are obvious, flexible, not easy to damage, strong blasting force, and corresponding impact force. It is precisely because of this characteristic that people make protective films for packaging on newly produced goods, and actually make protective films on goods to protect the appearance of the goods and enhance the impression of customers. Heat-shrinkable film is widely used in the complete packaging of mainstream products, cans, mineral water, various beverages, cloth and other products. PE heat shrinkable film and components to improve heat resistance, toughness, toughness, etc. The upper part of the surface film is paint, the main component in the middle is PVC, and the lower layer is coated with adhesive. The shrink film is designed using the principle of the stretching direction of the polymer molecular chain and is formed by quenching. After the polymer in a highly elastic state is stretched, the polymer is rapidly cooled to below the glass transition temperature, and the molecular direction is frozen. When heating in the process of packaging things, the thermal movement of the molecules causes stress relaxation, and the molecules return to their original state and shrink .
