General performance of PE heat shrinkable film

According to the PE heat shrinkable film manufacturer, the scope of application of heat shrinkable film in our lives is very wide, which brings great convenience to our lives, while keeping things and the environment tidy, so its function is still Very powerful. Let's take a look at its general performance. The first is shrinkage performance, which can also be seen from the name. Each shrink film used for packaging has different shrink strength, that is, has certain shrinkage characteristics. The shrinkage characteristics are determined by the type of polymer used during processing and processing conditions. The shrinkage characteristics are measured mainly by shrinkage rate, total shrinkage rate and orientation ratio. There is also shrinking temperature and heat-sealing performance. Most heat-shrinkable packages are heat-sealed first, and then heat-shrinked. When shrinking, both the film and the seal are subject to certain tension. The general performance of PE heat-shrinkable film includes the above two parts. It is these two parts that determine the performance of the heat-shrinkable film and also affect our use. Therefore, everyone should understand the knowledge of broken jade. Facilitate our use. Next: The role of heat shrinkable film Previous: No more
