Widely applicable for converting processing, or laminating with
acrylic base PSA side, rubber base adhesive, hot melts, inks,
cast materials and other special films, easy to peel off.
1. Packaging decoration:
PET release film can be aluminized by vacuum aluminizing machine to
form a kind of aluminized cardboardwith metallic luster, which is
characterized by degradable and recyclable environmental attributes
and is a green,novel and advanced packaging material that has just
been developed.
2. Transfer:
PET transfer film can also be referred to as PET transfer film,
which is characterized by its reusability.
It can be used in the field of printing on the one hand, PET
release film can be transferred to glass, porcelain, plastic,
metal, leather and cotton textile and other material objects by
heating and pressure through a special process; on the other hand,
it can also be used in highly integrated chemical, plate making,
vapor deposition, precision molds and molding of high-tech
industries.
3. Protective film:
PET release film can also be applied to the production of PET
protective film material, so it can be used not only for the
protection of stainless steel, nameplates and aluminum panels, as
well as laptop cases, display screen protection, can also be
applied to electronic die-cutting, photoelectric die-cutting,
electronics and other products in the process of protection.
4. Reflective film:
First-class PET release film can be made into PET reflective film
through a special process, which has excellent optical properties,
thermal stability and light aging resistance, etc. It is mainly
used in reflective requirements for reflective traffic signs,
billboards and industrial safety signs, etc.
