0.03mm PET Release Film
At 30μm, this PET release film is thin enough to follow tight die-cut contours, yet stable enough to stay flat through high-speed lamination. It is made for converters who need a liner that separates cleanly without curling, stretching, or leaving silicone marks on the adhesive. The release surface stays smooth and the base film holds its shape even after heat exposure.
