Product Description
40μm Natural Color Cast Polypropylene Silicone Coated Release Film
This 40-micron translucent white cast polypropylene silicone coated release film serves as a high-performance release liner primarily used in the manufacturing of pressure-sensitive adhesive tapes, labels, and various coated products. With its 40-micron thickness, the film offers excellent flexibility and robust mechanical properties.
Primary Applications
- Pressure-Sensitive Tapes: Used as backing material for packaging tapes, masking tapes, and other adhesive tape varieties
- Labels: Functions as release liner backing for labels across food and beverage, pharmaceutical, and personal care industries
- Specialty Coated Products: Provides reliable release mechanism for protective films, transfer tapes, and laminates
- Graphics and Signage: Serves as backer material for self-adhesive signs and graphics applications
The film delivers consistent release performance for adhesive products while its translucency offers visual appeal, making it ideal for labeling applications where underlying surfaces need to remain visible.
CPP vs PE Silicone Coated Release Film Comparison
Cast Polypropylene (CPP) Advantages: Superior transparency and clarity, enhanced moisture resistance, improved chemical resistance, better dimensional stability, and higher melting point for temperature-resistant applications including food packaging.
Polyethylene (PE) Advantages: Greater flexibility and softness, excellent elasticity, superior low-temperature performance suitable for cold storage and transport conditions.
