Silicone coated PET release film is a polyester-based release liner used for controlled peel, stable web handling, and clean adhesive converting. PET is widely chosen for this role because it combines high mechanical strength, strong thermal resistance, dimensional stability, flatness, and consistent thickness, while the silicone surface delivers predictable release values for pressure-sensitive applications. That is why current technical and supplier pages position it for labels, tapes, medical materials, electronics, and other precision converting work.
Product profile
PET Film Supply Company is the production manufacturer of this material for converters, coaters, and industrial buyers who need a stable liner for PSA processing. Compared with paper liners, PET is often selected when the job needs better moisture resistance, lower risk of curl or wrinkling, stronger tension handling, and cleaner performance in heated or automated converting. Clear PET also helps with visual inspection in some coating and laminating processes.
Benefits
- Stable release performance for pressure-sensitive adhesive converting
- High tensile strength for slitting, winding, and die cutting
- Low shrinkage and good dimensional stability under heat
- Smooth and flat surface for cleaner coating and lamination
- Available in single-side, double-side, and differential constructions
- Suitable for labels, tapes, medical, and electronics uses
How do you choose the right release level?
The right release level depends mainly on adhesive chemistry, coating weight, unwind speed, and what happens after release. Easy release is commonly used when fast separation is needed. Medium or tight release is usually better for more aggressive adhesives or for lines that need stronger liner control during rewinding, laminating, or die cutting. Differential constructions are useful when the two sides of the liner need different peel behavior. In practical sourcing, the best grade is the one that stays stable from storage to final converting, not simply the one with the lowest peel value on paper.

Which is better: single-side or double-side silicone coating?
Single-side coating is usually the practical option when only one release face is needed, such as in many standard tape and label structures. Double-side coating is more suitable when both surfaces require controlled release, when the film is used as an interleaf, or when the product design needs different peel behavior on each side. Current supplier material shows that one-side, two-side, and differentiated options all exist because the correct format depends on the end-use structure, not on one version being universally better.
