Product Description
40μm Opaque Red PE Release Film
Silicone UV cured release film designed for protective and packaging applications, tapes, labeling, and graphics.
Product Overview
This 40-micron opaque red PE silicone coated release film serves as a high-performance release liner for adhesive product manufacturing. The 40-micron thickness provides excellent flexibility and handling characteristics while maintaining durability.
Key Applications
- Label Industry: Backing material for self-adhesive labels in food and beverage, packaging, and industrial applications. The distinctive red color offers visual differentiation and appeal.
- Graphic Art Industry: Used for creating vinyl graphics, cut lettering, and decals. The red film enables easy identification of the liner from the adhesive side.
- Electrical and Electronic Industry: Protective tapes and insulating materials for electronic components and assemblies.
- Automotive Industry: Inner or outer liner for double-sided tape used in attaching body trims, molding, and automotive parts.
Manufacturing Process
Silicone Coating Application
- Film Preparation: Surface cleaning and treatment with corona discharge or plasma to enhance surface energy and adhesion.
- Silicone Application: Even application using spraying, dipping, or roll coating methods with precisely controlled viscosity and concentration.
- Silicone Curing: High-temperature curing above 120°C for uniform crosslinking and optimal adhesion to the PE substrate.
- Finishing: Precision trimming or die-cutting to required specifications using specialized equipment.

UV Curing Technology
UV curing has emerged as a preferred method for silicone coating on PE film, utilizing ultraviolet light to initiate chemical reactions for curing and crosslinking instead of traditional heat-based methods.
UV Curing Advantages
- Faster Processing: Cures silicone coating in seconds compared to conventional heat curing methods.
- Energy Efficiency: Lower energy consumption and reduced carbon footprint for environmentally conscious manufacturing.
- Superior Coating Quality: Uniform silicone application with excellent adhesion and chemical resistance properties.
- Increased Productivity: Reduced production times through faster curing cycles.
- Substrate Protection: No heat damage to the PE film, preserving substrate integrity and properties.
