BOPP release film, also known as silicone oil film or anti-adhesive film, is made by coating BOPP base film with a uniform layer of organic silicone—available in single-sided or double-sided, and in solvent or solvent-free formulations. It provides excellent release properties, stable performance and high cleanliness, making it widely used in labels, adhesives, die-cutting, electronics, tapes and industrial material processing.
Product Overview
The film surface is smooth and uniform, with no wrinkles, creases or rainbow lines, ensuring consistent performance during high-speed coating, laminating and die-cutting. Our independently developed solvent-free silicone coating technology offers enhanced stability, environmental friendliness and improved release uniformity compared with traditional solvent systems.
Key Features & Advantages
- High cleanliness: suitable for precision applications such as optical materials, electronics and medical components.
- Uniform silicone coating: ensures consistent release force and smooth peeling.
- Multiple colors available: transparent, blue, red, white, milky, black and matt for different identification and process needs.
- Wide thickness range: transparent 12–100 μm; colored 50–100 μm.
- Custom widths: 20–1540 mm to match slitting and coating requirements.
- Flexible release force options: ultra-light to ultra-heavy release levels for different adhesives and applications.
- Printable: supports single-color printing for batch codes or branding.
