Features of PE heat shrinkable film

There are many types of shrink films produced by PE heat shrinkable film manufacturers. Because the occasions are different, the characteristics of the bureau are also different. The first thing we need to know is that PE shrink film is a kind of shrink film with a long history. It is a heat shrinkable film produced using polyethylene as a raw material. It is different from PVC shrink film, which is produced by ordinary blown film technology. It requires a higher temperature during processing, which is much higher than the melting point of polyethylene. Therefore, low-density polyethylene with a large amount of long-chain branched structure is generally used as the production raw material. In this way, a film with sufficient lateral shrinkage can be obtained, and it has good performance when used. In recent years, with the development of catalyst technology and polymerization process, some new metallocene polyethylene and linear low-density polyethylene can not only provide excellent mechanical properties, but also provide better lateral shrinkage properties.
