Fluorosilicone Release Liners for Medical Silicone Adhesives

Built for the documentation depth medical qualification demands — clean, low-transfer release for transdermal patches, wound dressings, and wearables, with the lot traceability and release stability that regulated programs depend on.

In medical adhesive systems, the liner is part of the quality record — not just packaging. Jefluo fluorosilicone liners hold release force and peel performance consistent through sterilization, aging, and long storage, so what comes off the line on day one behaves the same way at the point of use. Liner integrity here is product integrity.

Key Benefits

Ultra-Low Release Force for Medical Coatings

Fluoro-silicone liners designed to deliver ultra-low and stable release force, ideal for coating medical-grade adhesives used in transdermal patches, wound dressings, and wearable devices. Supports clean release during converting and application.

Reliable Adhesive Compatibility

Performs consistently with a wide range of silicone adhesives, even with customized formulations used by different medical device manufacturers. Suitable for precision drug delivery and diagnostic applications.

EtO & Steam Sterilization Compatibility

Our PET-based fluoro-silicone liners are made with materials compatible with EtO and steam sterilization processes under typical medical packaging conditions. We support wound care and device manufacturers with guidance and testing upon request.

Applications

Transdermal drug delivery patch applied to a patient's upper arm.

Transdermal Patches

Transdermal drug-delivery patches use precisely coated silicone gel adhesives for reliable skin contact. Our fluorosilicone liners provide clean release and stable adhesive protection through coating and converting. This supports accurate, low-defect production of pharmaceutical patches.
Wound care dressing with border adhesive applied to a patient's forearm.

Wound Care Dressings

Advanced wound dressings use soft silicone gel adhesives for secure, atraumatic skin contact. Our fluorosilicone liners provide consistent release and protect the adhesive during precise die-cutting. They also support constructions that must withstand EtO or steam sterilization.
Wearable medical sensor applied to the upper arm.

Wearable Medical Devices

Long-wear monitoring and diagnostic devices use skin-contact silicone gel adhesives for reliable fixation. Our fluorosilicone liners provide clean release and stable coating for biosensors and skin-worn devices. This supports low-defect, multilayer converting workflows.
Silicone cosmetic under-eye patch applied to a woman's face.

Scar & Cosmetic Patches

Scar-treatment and cosmetic patches use soft, repositionable silicone gel adhesives for gentle skin contact. Our fluorosilicone liners provide clean release and stable coating for these silicone adhesive constructions. This supports precise converting of repositionable, reusable patches.

Customized Fluorosilicone Release Liners for Medical Applications

Fluorosilicone release liners for medical applications are configured around three variables: release force level, substrate thickness, and sterilization compatibility. Selection depends on adhesive tack, converting method, and downstream assembly requirements.

Frequently Asked Questions

Selected Jefluo liners are compatible with ethylene oxide (EtO) and steam sterilization processes. Suitability depends on liner configuration and adhesive system — we recommend confirming compatibility against your specific sterilization protocol and packaging requirements.

For medical silicone PSA applications, release force typically falls in the ultra-low to low range — under 3 g/in for transdermal patches, and 3–10 g/in for woundcare films and wearable devices. The appropriate range depends on adhesive tack, liner substrate, and the specific removal requirement of the application.

Our liners are tested annually by SGS against regulated PFAS substance lists under EU REACH and US EPA definitions. No PFAS substances have been detected. Full test documentation is available upon request.

Yes. Jefluo provides DMF documentation upon request to support regulatory submissions for drug delivery systems, especially for transdermal and pharmaceutical applications.
