ISO Translucent Red Cast Polypropylene Silicone Coated Release Film
40μm red color cast polypropylene silicone coated release film designed for food, medical, and industrial packaging applications.
This specialized 40-micron translucent red or opaque red cast polypropylene silicone coated release film serves as a color-coded release liner for applications requiring product differentiation. The distinctive red color enhances product visibility and identification compared to standard white or clear release films.
Primary Applications
- Automotive and Aerospace: Used in production of parts and components requiring color-coded release films for easy identification
- Labels: Differentiates product lines, families, and specific ingredients in consumer items, food service products, personal care products, and pharmaceutical packaging
- Graphic Arts: Serves as backer material for vinyl graphics and decals
- Signage: Used in production of colored signs and banners
This release film provides a reliable and consistent release surface while maintaining identical physical properties to clear release liners, including chemical resistance, barrier properties, and strength.
CPP vs PE Release Film Comparison
Cast Polypropylene (CPP) Advantages:
- Superior transparency and clarity
- Enhanced moisture resistance
- Improved chemical resistance
- Better dimensional stability
- Higher melting point for temperature resistance
- Ideal for food packaging and pouches
Polyethylene (PE) Characteristics:
- Softer and more flexible
- Excellent elasticity
- Superior low-temperature performance
- Suitable for cold storage and transport
