Silicone Coated Release Liner

Protective Film Rolls Company is a manufacturer of silicone coated release liner made with PET film carrier and a controlled silicone release surface. This PET release liner is used for adhesive converting, lamination, die cutting, tape production, labels, and protective film applications. It protects pressure-sensitive adhesive, keeps the adhesive surface clean, and supports smooth peeling under matched release conditions.

Packing and Loading

Product Overview

This silicone coated release liner works as a clean process layer for adhesive-coated materials. It carries and protects adhesive during coating, laminating, rewinding, slitting, die cutting, storage, and final application.

The PET base film provides flatness, tensile strength, moisture resistance, and thickness consistency. In narrow-width slitting or precision die cutting, unstable tension can cause curl, edge movement, or waste-removal problems. For clear adhesive films and electronic materials, the transparent carrier also helps check coating uniformity, particles, bubbles, and edge quality.

Protective Film Rolls Company produces silicone coated PET film with single-side, double-side, and differential release options. The silicone layer creates a controlled low-adhesion surface between adhesive and film. Very easy release is not always safer. If release is too light, adhesive may lift during rewinding. If too tight, peeling may cause stretching, edge lifting, or difficult waste removal. The right release level depends on adhesive type, coating weight, pressure, storage time, line speed, and final peeling method.

Benefits

• Controlled peeling: Smooth release without release jumps, liner drag, stretching, or edge lifting.
• Stable film support: PET film carrier helps reduce deformation during slitting, laminating, rewinding, and die cutting.
• Cleaner adhesive surface: The silicone release film protects adhesive from dust, blocking, fiber contamination, and unwanted contact.
• Lower silicone transfer risk: Well-anchored silicone helps protect residual adhesion after liner removal.
• Better visibility: Clear PET film allows checking of particles, bubbles, coating marks, and edge condition.
• Flexible structures: Single side, double side, and differential release options support different converting processes.

How Does Silicone Coating Affect Release Performance?

Silicone coating controls how adhesive separates from the film liner during processing and final use. The release surface must be balanced. Too light, and adhesive can lift, shift, or lose roll stability. Too tight, and the liner may create peeling resistance, adhesive distortion, or die-cut waste-removal issues. Release performance is commonly checked by 180° peel testing, visual adhesive transfer inspection, and residual adhesion comparison. Samples are usually conditioned with 24h adhesive contact before peel testing.

When Should You Use a PET Carrier Film Instead of Paper-Based Release Liner?

A PET-based carrier is useful when adhesive products need stable dimensions, cleaner surface contact, and better process control. Paper liners can work for general labels, but they may absorb moisture, curl, tear, or release fibers during converting. Film-based liners are often used for clear adhesive materials, electronics, narrow-width slitting, precision die cutting, and applications where flatness is important. They also reduce fiber dust risk and allow easier visual inspection.

Applications

• Adhesive tape production: Used as a release liner for adhesive tapes during coating, winding, storage, and conversion.
• Labels and stickers: Helps label stock release cleanly during converting and final application.
• Die-cut adhesive parts: PET film carrier helps maintain flatness and registration during cutting and waste removal.
• Protective film lamination: Works as a temporary liner where adhesive surfaces need clean protection.
• Electronic materials: Suitable for low-fiber applications where dust, moisture, or contamination can affect processing.
• Double-sided adhesive structures: Differential release separates each adhesive side and reduces blocking during rewinding.

FAQ

What is a silicone coated release liner used for?

It protects adhesive surfaces during coating, lamination, die cutting, storage, and final application. The silicone surface allows clean separation when needed.

Is PET release liner better than paper release liner?

It is usually better for transparency, moisture resistance, cleaner converting, or tighter dimensional control. Paper liner is useful for cost-sensitive label work.

Can the release force be adjusted?

Yes. Release force can be adjusted as light, medium, tight, or differential release by adhesive type, speed, contact time, and peeling requirement.

What is the difference between single side and double side silicone coating?

Single side coating is used when only one adhesive-contact surface needs release performance. Double side coating is used when both sides need anti-blocking, clean unwinding, or multi-layer processing.
