Ordinary PET film does not have heat sealing performance-film supplier

by:POLYVA     2022-01-31
Ordinary PET is a crystalline polymer. After the film is stretched orientated, it will produce a greater degree of crystallization. If it is heat-sealed, it will shrink and deform, so ordinary films do not have heat-sealing properties. When the film is used for commodity packaging, in order to solve the heat sealing problem, the method of combining BOPET film with PE film or CPP film is usually adopted, which limits the application of BOPET film to a certain extent. It is a company specializing in the production of PET film with multiple functions, such as: transparent PET film, milky white PET film, release PET film, supply of PET motor film, etc. With a wide variety of products, affordable prices, and environmental protection, we provide customers with excellent quality and service based on the service tenet of excellence in production, honesty and trustworthiness in distribution, and warm and thoughtful service.
