Protective Film Rolls Company is a non silicone release film manufacturer producing release films for adhesive processes that need clean liner removal with no silicone transfer from the release surface. Instead of a standard silicone layer, this film uses a non-silicone coating for acrylic, rubber-based, hot-melt, resin-contact, and other silicone-sensitive adhesive systems. It supports controlled peel force, clean adhesive contact, and stable performance during coating, lamination, die-cutting, and electronic material processing.
Product Overview
This non silicone release film is made for applications where the liner surface can affect the final adhesive part. A silicone-coated liner may be enough for general use, but not when the adhesive face must stay clean for bonding, printing, coating, electrical contact, or precision lamination.
The coated release side gives sensitive adhesive materials a cleaner contact surface. It is used for electronic adhesive parts, optical bonding materials, medical adhesive components, FPC process parts, resin-coated films, and precision die-cut products. In these uses, surface residue may cause weak bonding, uneven coating, poor print adhesion, unstable conductivity, or lower assembly yield.
From our factory view, we check coating uniformity, peel consistency, winding tension, slitting edge, and coating anchorage. During sample review, we compare initial peel with aged peel. A film may release smoothly at first, then become tight after heat storage, long-roll pressure, or stronger adhesive chemistry. We use 180° peel, 300 mm/min peel speed, and 70°C × 20h aging when stability needs confirmation.
Benefits
- Cleaner release contact: Helps protect adhesive surfaces where residue may affect bonding, coating, conductivity, printing, or assembly.
- Non-silicone release layer: Keeps the adhesive face cleaner than a standard silicone-coated liner in sensitive converting.
- Controlled peel force: Light, medium, and heavy grades can be adjusted after actual adhesive testing.
- Adhesive compatibility: Works with acrylic, rubber-based, hot-melt, resin coating, and specialty pressure-sensitive adhesives.
- Testable stability: Release force can be checked by 180° peel, 300 mm/min speed, and 70°C × 20h aging.
- Process control: Coating smoothness, roll tension, edge quality, blocking risk, anchorage, and batch consistency help reduce heavy peel spots and coating transfer.
What Makes the Release Surface Different for Sensitive Adhesives?
A sensitive adhesive needs more than easy peeling. It needs a contact surface that does not disturb the adhesive before use. This film creates a clean separation layer between liner and adhesive, helping reduce contamination risk before bonding, lamination, or die-cut assembly. This matters for electronic tapes, optical adhesive films, FPC parts, sensor materials, and precision die-cut components where bonding strength must remain stable after liner removal.

How Should the Release Force Be Checked Before Bulk Use?
Before regular production, test release force with the actual adhesive, not only a standard lab tape. A non-silicone coated surface can behave differently with adhesive chemistry, coating weight, lamination pressure, storage time, temperature, and peeling speed. A useful test compares initial peel, aged peel, residual adhesion, surface cleanliness, coating anchorage, blocking risk, and coating transfer. For this film, the best result is not always the lowest peel force. A better result is stable separation without silicone transfer, heavy peel increase, adhesive contamination, coating transfer, or bonding loss after storage and converting.

FAQ
Is this the same as normal PET release film?
No. It uses a non-silicone coating and silicone-free release surface, not a standard silicone-coated PET release layer.
Can it be used for silicone-sensitive adhesive systems?
Yes. It is made for adhesive contact surfaces where silicone transfer should be reduced or avoided.
What should be tested before production?
Initial peel, aged peel, residual adhesion, coating anchorage, blocking, coating transfer, and adhesive surface cleanliness.
Can the release force be adjusted?
Yes. Light, medium, or heavy release grades can be developed after testing the actual adhesive sample.
