Ordinary PET film does not have heat sealing performance. Source: Protective film factory direct sales Release time: 2019-03-10 Hits: 3663 Ordinary PET is a crystalline polymer. After the PET film is stretched orientated, it will produce a greater degree of crystallization. If it is heat-sealed, it will shrink and deform, so ordinary PET film does not have heat-sealing performance. When PET 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.
