50μm Opaque White Cast Polypropylene Silicone Coated Release Film
Cast polypropylene (CPP) silicone coated release film is widely used as a release liner for pressure-sensitive adhesive products and as a protective layer for sensitive surfaces. This high-performance material offers excellent clarity, stiffness, and tear resistance, making it the preferred choice for numerous industrial applications.
Primary Applications
Label Production
CPP silicone coated release film serves as the release liner for pressure-sensitive labels and stickers, providing easy removal from backing material. Its superior clarity and exceptional flatness ensure high-quality label printing results.
Tape Production
Used as the release liner for pressure-sensitive adhesive tapes including masking tape, duct tape, and specialty tapes. The film's high strength, dimensional stability, and excellent printing capabilities make it ideal for these applications.
Screen Printing
Functions as transfer tape in graphic arts and screen printing applications, delivering strong adhesion and clean transfer of graphics or text onto various surfaces.
Automotive Industry
Provides protective layering for car part surfaces during transportation, painting, and industrial processes, safeguarding against scratches and damage.
Electronics Industry
Acts as a protective barrier for sensitive electronic devices during assembly and transportation, preventing contamination from dust, moisture, and other environmental factors.
Mechanical Performance Characteristics
Although designed for single-use applications, CPP silicone coated release film requires high-performance mechanical properties to ensure optimal functionality:
- Processing Efficiency: Appropriate stiffness, tensile strength, and elongation properties enable efficient handling during manufacturing and conversion processes
- Surface Protection: Robust construction resists punctures, tears, and abrasions during handling, transportation, and storage
- Clean Release Performance: Dimensional stability, flatness, and smooth surface ensure consistent, residue-free release from adhesives
These mechanical properties are essential for protecting underlying surfaces, facilitating manufacturing processes, and delivering reliable release performance in disposable applications.
