0.125mm PET Release Film
When the job is heavy and the tolerance is tight, 0.125mm PET release film is the one that holds the line. At 125μm this is among the thickest grades in the release film range — a true industrial-weight liner that stays flat under load, resists edge curl through repeated rewinding, and gives oversized dies a rock-solid base to cut against.

FAQ
When should I choose 0.125mm?
When the job is heavy and the tolerance is tight. It stays flat under load and resists edge curl through repeated rewinding.
What does light release mean?
The liner peels away with low force: 0.07 N/50mm at room temperature and 0.12 N/50mm after 24 hours at 70°C, with 95% residual adhesion.
Can you slit or cut the film?
Yes. We offer custom slitting into rolls, sheet cutting, and widths made to order.
Can I get samples?
Contact us with your adhesive type, width and quantity, and we will send a quote and samples.
