Non Silicone Release Liner

PET Film Supply Company is a Non Silicone Release Liner manufacturer making PET-based liners for adhesive processes where silicone transfer can cause defects. This liner uses a controlled silicone-free release coating for OCA lamination, electronics die cutting, medical adhesive tape converting, and other silicone-sensitive work. With 25μm–125μm film options and adjustable release levels, it keeps adhesive surfaces cleaner during slitting, kiss cutting, rotary die cutting, rewinding, and small part handling.

Product Overview

Non Silicone Release Liner is used when the adhesive surface cannot risk silicone migration or unknown residue. In OCA, display module, sensor, camera module, medical patch, and wearable tape production, a normal silicone liner may peel smoothly but still leave trace residue. That residue may reduce wet-out, weaken bonding, create fisheye marks, affect optical clarity, or cause unstable lamination after die cutting.

Our non silicone PET release film uses stable PET base film with controlled release chemistry. Compared with paper liners, PET gives better dimensional stability, cleaner die-cut edges, lower fiber dust, and stronger web handling during narrow-width slitting. For small adhesive parts, the liner must keep pieces flat and correctly positioned after waste matrix removal.

For optical bonding, this film can work as an OCA release liner before lamination or precision cutting. In trial runs, release force is checked with adhesive thickness, cutting depth, waste removal speed, roll tension, and storage condition. If it releases too easily, parts may shift. If it holds too tightly, adhesive pulling, edge lifting, liner breakage, or uneven waste removal may appear. Testing with the actual adhesive stack is recommended before bulk production.

Benefits

• Keeps adhesive surfaces cleaner before bonding, lamination, pouching, automated pick-and-place, or final assembly.
• Supports optical adhesive work where clarity, wet-out, low fisheye risk, and clean bonding are important.
• PET film offers better tear resistance, dimensional stability, and lower fiber dust than paper liner.
• Controlled release force helps reduce edge lifting, adhesive pulling, liner breakage, and small part movement.
• Suitable for kiss cutting, rotary die cutting, slitting, laminating, rewinding, and waste matrix removal.
• Cleaner surface control helps reduce dust, pinhole, scratch, fisheye, particle, and coating defect concerns.
• Clear or blue film helps with visual inspection, process identification, and defect checking.

When Should You Use a Non Silicone Release Liner?

Use a non silicone release liner when silicone transfer may affect bonding, coating, printing, optical clarity, or electronic assembly. In OCA lamination, display adhesive die cutting, medical tape converting, and precision electronic parts, even slight contamination may cause adhesion loss, poor wet-out, fisheyes, unstable bonding, poor final part transfer, or failed visual inspection. The non-silicone coating helps keep the adhesive surface cleaner during storage, slitting, kiss cutting, liner removal, and automated assembly.

Applications

• OCA lamination and die cutting for display modules, touch panels, optical bonding layers, and clean adhesive transfer.
• Electronics adhesive parts for sensors, camera modules, speakers, insulation pads, and display bonding parts.
• Medical double-sided tape, wearable patches, skin-contact adhesive materials, and wound dressing components.
• Silicone-sensitive acrylic adhesive laminates and precision pressure-sensitive materials.
• Clean release PET liner for coating, laminating, slitting, rewinding, and part transfer.
• Small adhesive part die cutting requiring stable waste matrix removal, low shifting, and clean edge release.

How Does Silicone-Free Release Coating Improve Die Cutting Stability?

Silicone-free release coating gives the adhesive layer a controlled release surface without using silicone chemistry. During OCA and electronic tape die cutting, the liner must release smoothly while holding the adhesive in place. Good balance helps avoid edge lifting, adhesive transfer, liner breakage, part shifting, and uneven waste removal. A PET-based low-contamination liner also gives better web stability than paper during narrow-width slitting, rotary die cutting, and small adhesive part transfer. For soft medical tape, stable release can reduce adhesive distortion when thin skin-contact materials are cut into small shapes.

FAQ

What makes Non Silicone Release Liner different from standard silicone release liner?

It uses a silicone-free release coating to reduce silicone transfer risk on sensitive adhesive surfaces.

Can the release force be adjusted?

Yes. Common ranges include 5–30 g/in, 30–80 g/in, and 80–150 g/in.

Is PET film better than paper liner for precision die cutting?

For clean converting, PET usually gives better dimensional stability, lower dust, smoother edges, and stronger web handling.

What should be confirmed before selecting this liner?

Confirm adhesive chemistry, release force, liner thickness, coating side, cleanliness level, die cutting method, roll width, temperature exposure, storage condition, and final bonding requirements.
