80μm to 120μm Opaque White PE Silicone Coated Release Film with UV Cured Silicone for Protective Packaging

80 μm translucent white PE release film with silicone UV curing, designed for protective packaging, tapes, labeling, and graphics applications.

80 micron to 120 micron opaque white PE silicone coated release film serves as a release liner in the manufacturing of various adhesive products. The opaque white color provides a solid, non-transparent surface that effectively conceals the adhesive or product underneath. The silicone coating ensures a non-stick surface for easy release during product assembly or application.

• Automotive Applications: Used in protective films for painted surfaces and vehicle wrapping applications. The thicker gauge provides superior scratch resistance and protection.
• Medical Applications: Employed in wound dressings, adhesive patches, and transdermal drug delivery systems. The thicker gauge offers extra strength and durability for applications requiring higher protection levels.
• Industrial Applications: Utilized in heavy-duty tapes, foam bonding, and insulation products. The thicker gauge provides additional strength for applications demanding higher durability and protection.
• Construction Applications: Applied in protective films for windows, roofing systems, and other building materials. The thicker gauge delivers superior weather resistance and damage protection.

• Film Preparation: Surface preparation through cleaning and treatment with corona discharge or plasma to enhance surface energy and ensure good silicone adhesion.
• Silicone Application: Application using spraying, dipping, or roll coating methods with precisely controlled viscosity and concentration for even distribution.
• Silicone Curing: High-temperature curing typically above 120°C for uniform curing and optimal adhesion to the PE substrate.
• Finishing: Trimming or die-cutting to required sizes and shapes using specialized equipment.

UV curing method utilizes ultraviolet light to initiate chemical reactions in silicone, causing it to cure and crosslink. This modern approach offers significant benefits over traditional heat curing methods.

• Faster Curing Time: Cures silicone coating in seconds compared to traditional methods.
• Energy-Efficient & Eco-Friendly: Lower energy consumption and reduced carbon footprint.
• High-Quality Coating: Uniform coating with excellent adhesion and chemical resistance.
• Reduced Production Time: Faster processing times increase manufacturing efficiency.
• No Heat Damage: Preserves substrate properties without thermal degradation.

The stripping ratio (release force required to remove silicone-coated release liner from adhesive) can be precisely controlled by regulating silicone coating weight on each film side.

• Determine Required Ratio: Establish specific application requirements for each side.
• Adjust Coating Weight: Modify silicone application to control coating thickness and release characteristics.
• Conduct Testing: Use tensile testers or release force testers to measure removal force.
• Optimize Parameters: Adjust coating weight, temperature, and solvent systems to achieve desired release ratios.

Establishing clear coating process parameters ensures consistent symmetrical release ratios through optimal silicone wetting and adhesion control.
