Transparent PET Release Film Modified PET Film
Description:
| It is modified polyester, we called as Modified PET release film, possesses high elongation at break, largely ameliorates the problem of causing big and deep wrinkles at the transverse direction while downstream production by using BOPET(Biaxially oriented PET) release film.
|
Advantages:
► High temperature resistance, up to 160℃
► High subsequent adhesion rate, up to 90%, less silicon tranfer
► It is soft than PET film, tear resistance, high strength
► More thinner, can be do at 20 micron
► No color change, easy to peel off when use
► Make the products' surface more flat
► High elongation, more than 150%
