With the continuous changes in market demand, heat shrinkable films are developing in a multi-layered and functional direction. Many new technologies and new products have been introduced. The multi-layer co-extruded composite heat shrinkable film uses linear low-density polyethylene as the middle layer. As the inner and outer layers, co-extrusion polypropylene is made by co-extrusion. It has the advantages of PE and PP, which is better than single-layer PE or PP film. It is a heat-shrinkable packaging material widely used internationally. Single-layer heat-shrinkable films are widely used in fast food and pasta, and multi-layer heat-shrinkable films are also widely used in fresh meat and fatty food packaging. Therefore, the development trend of PE shrink film packaging film in the food industry is getting better and better. The advantages of PE shrink film packaging: 　　1) Beautiful appearance, close to the product, so it is also called skin packaging, suitable for various shapes of product packaging; 　　2) Good protection, if the inner packaging of the shrink packaging is hung on the outer packaging　　3) Good cleaning performance, especially suitable for packaging of precision instruments and high-precision electronic components; 　　4) Good economy; 　　5) Good anti-theft performance, a variety of food It can be packed together in a large shrink film to avoid loss; 　　6) Good stability, the product will not sway in the packaging film; 　　7) Good transparency, customers can directly see the content of the product.
