75μm PET Silicone Film
This 75μm PET silicone film is the heavier-body option in our light-release range. The extra thickness helps the liner stay flat and stable during large-format die-cutting and repeated rewinding, where thinner liners such as our 50μm and 38μm grades tend to wrinkle or curl more easily. As a wholesale supplier, Jinlu Film ships this grade in bulk with custom slitting and sheet cutting.
Release Performance
Release strength is 0.07 N/50mm at room temperature and 0.12 N/50mm after 24 hours at 70°C, measured with the standard 31B test tape. This is a light-release grade: the liner peels away with low force. Residual adhesion is 95%, which means the adhesive keeps almost all of its tack after the liner is removed.

Typical Applications
- Large-format die-cutting, where a stiffer liner holds its shape
- Pressure-sensitive adhesive liner and label stock
- Protective film
- Electronics assembly
- Molding release
Choosing the Right Thickness
Thicker liners give more body and flatness, while thinner liners are lighter and generally allow more length per roll. Our silicone-coated PET range also includes 12μm, 19μm, 25μm and 30μm. You can browse the full range in our PET release film category. If you are unsure which side of a release film carries the coating, see our guide to single-sided vs double-sided release film.
FAQ
What does 0.07 N/50mm mean?
It is the force needed to peel a 50 mm wide standard test tape from the silicone surface. A lower number means easier release.
Can you slit or cut this film to size?
Yes. We offer custom slitting and sheet cutting.
Can I get samples?
Yes. Contact us with your application and required size, and we will send a quote and samples.
