25μm PET Silicone Film
As a PET Silicone Film Factory, Jinlu Film runs this 25μm grade as one of our highest-volume release film specifications. It is the thickness most converters settle on after testing thinner and thicker options — thin enough for compact labels and precision die-cutting, thick enough to feed reliably through high-speed lines. Release holds at 0.07 N/50mm at room temperature and 0.12 N/50mm at 70°C, with 95% residual adhesion so adhesives keep their tack after peeling.

FAQ
Why is 25μm so popular?
It is the thickness most converters settle on after testing thinner and thicker options: thin enough for compact labels and precision die-cutting, thick enough to feed reliably through high-speed lines.
Will the adhesive keep its tack after peeling?
Yes. Residual adhesion is 95%, so adhesives keep their tack after the liner is removed.
Can you slit or cut the film?
Yes. We offer custom slitting and sheet cutting, with factory-direct pricing.
Can I get samples?
Contact us with your adhesive type, width and quantity, and we will send a quote and samples.
