0.025mm PET Release Film
This 25μm PET release film is a light-release liner designed for clean, consistent separation in labeling, die-cutting, and protective film applications. It releases smoothly at both room temperature and under heat, and the release surface keeps its low wetting tension so adhesives come away cleanly without residue or drag.
