60μm Opaque Green PE Release Film
60-micron opaque green PE silicone coated release film is a specialized release liner designed for adhesive product manufacturing including tapes, labels, and various coated materials.
Primary Applications
Label Industry
Widely used as backing material for self-adhesive labels in food and beverage labeling, packaging, and industrial applications. The distinctive green color provides visual appeal and product differentiation.
Graphics Industry
Ideal for creating vinyl graphics, cut lettering, and decals. The green film enables easy identification of the liner from the adhesive side.
Electrical and Electronic Industry
Used for protective tapes and insulating materials. The film's thickness and rigidity withstand manufacturing and application stresses.
Medical Industry
Employed in producing wound dressings and advanced wound care products.
Automotive Industry
Used for double-sided tapes to attach body trims, molding, and other automotive components.
Manufacturing Process
- Film Preparation: Surface cleaning and treatment with corona discharge or plasma to enhance surface energy
- Silicone Application: Even application via spraying, dipping, or roll coating with specific viscosity and concentration
- Silicone Curing: High-temperature curing above 120°C for uniform adhesion to PE substrate
- Finishing: Trimming or die-cutting to required specifications

UV Curing Advantages
UV curing utilizes ultraviolet light to initiate chemical reactions in silicone, offering significant benefits over traditional heat curing methods:
- Faster Curing Time: Cures silicone coating in seconds rather than minutes
- Energy-Efficient & Eco-Friendly: Lower carbon footprint with no high heat requirements
- High-Quality Coating: Uniform silicone coating with excellent adhesion and chemical resistance
- Reduced Production Time: Faster processing increases manufacturing efficiency
- No Heat Damage: Preserves substrate properties throughout production
Release Ratio Control
The stripping ratio (force required to remove release liner from adhesive) is controlled through precise silicone coating management:
- Requirement Definition: Determine specific release ratio needs for each application
- Coating Weight Adjustment: Regulate silicone thickness on each film side
- Comprehensive Testing: Use tensile or release force testers for accurate measurement
- Process Optimization: Adjust coating parameters until desired release ratio is achieved
