Silicone Coated Polyethylene Films
- Base film: flexible LDPE or application-specific HDPE
- Coating: single-side, double-side, or differential release
- Release level: easy, medium, or tight grade
- Supply format: master rolls or custom slit rolls
- Roll setup: core size and silicone side in or out confirmed
- Uses: tape, label, foam adhesive, and hygiene-material converting
Films Protective Company is a manufacturer of silicone coated polyethylene films for adhesive-material converting. Each roll combines a flexible PE base film with a controlled silicone release coating on one side or both sides. The film is suitable for slitting, lamination, die cutting, rewinding, and dispensing where soft handling, steady unwinding, and predictable peeling are important. Release grade, roll format, winding direction, and operating temperature window are confirmed before production.
Product Overview
This silicone coated PE film is intended for processes where a soft liner performs better than a rigid carrier. LDPE grades are a practical option when conformability and elongation matter, particularly when the liner follows foam, tape, or other flexible adhesive structures. Application-specific HDPE grades can be used where slightly higher roll stability is needed during slitting, rewinding, or line feeding.
The film serves as a polyethylene release liner for adhesive converting. Its polysiloxane-based coating protects the adhesive face until separation. Sample approval should evaluate the liner together with the actual adhesive structure rather than as an isolated roll sample. Across the usable width, check coating continuity and local release-force variation. Where cleanliness is critical, review silicone rub-off, migration risk, and subsequent adhesion.
Benefits
- Flexible PE base film follows soft adhesive structures with less stiffness.
- Single-side, double-side, and differential-release options support different separation sequences.
- Adjustable release grades can be matched to adhesive chemistry and stripping speed.
- Custom slit rolls help fit downstream equipment and reduce extra rewinding.
- Flatness, slit-edge, and winding-direction checks support stable feeding.
- Approved samples and lot identification help maintain repeat-order consistency.
When Should Single-Side, Double-Side, or Differential-Release PE Film Be Selected?
Single-side coating is suitable when one surface carries adhesive and the reverse side remains available for winding or handling. Double-side coating is useful when both surfaces need non-stick performance. Differential-release PE film should be considered when one side must separate before the other during lamination, rewinding, stripping, or automatic dispensing. Test the final silicone-coated PE release liner structure with the actual pressure-sensitive adhesive, label stock, foam adhesive, or hygiene-material component. Where reduced peel noise matters, confirm the result on the intended equipment.

How Should Roll Tension and Peel Testing Be Confirmed Before PE Release Film Enters Converting?
Before a production lot is approved, review web tension, unwind tension, line speed, acceleration, braking, guide-roller contact, static-control needs, and slit-roll alignment. Sudden stopping can increase telescoping risk, while repeated contact with stationary parts may damage the coated surface. Peel-force testing should use an agreed angle, speed, dwell time, ageing condition, and actual adhesive sample. For long rolls, compare outer-layer, middle-layer, and near-core material because winding pressure and release behavior can vary by roll position. Approved and retained samples should be linked to the lot number.
FAQ
How should the release grade be confirmed for a new adhesive?
Test the intended adhesive under an agreed peel angle, speed, dwell time, and ageing condition. A suitable grade may vary by adhesive system.
How can silicone rub-off or migration risk be checked?
Inspect the coated surface after handling and line trials. Where cleanliness matters, review subsequent adhesion and check the adhesive face for transfer.
How should partially used rolls be stored?
Return unused material to its original packaging after sampling or line trials. Keep rolls dry and away from sunlight, moisture, abrasion, and temperature fluctuation.
What should be confirmed before a repeat order?
Confirm the approved sample, retained sample, lot identification, PE grade, thickness, width, roll length, core size, winding direction, slit-width tolerance, and release-test condition.
