Biaxially oriented polypropylene matte film, after silicone coating on one or both sides, has excellent smoothness, anti-adhesive and abrasion resistance. Therefore, it can be applied in the following fields:
1. Packaging industry:
For food packaging, pharmaceutical packaging, cosmetic packaging, etc., it can improve the opening performance of the packaging, making it easier to open.
2. Printing industry:
Used for surface treatment of printed materials to enhance the glossiness and smoothness of the printed materials, making them easier to read.
3. Electronics industry:
t can be used for the packaging of electronic products such as mobile phones, computers, etc., to provide anti-skid and anti-scratch protection.
4. Label industry:
hen making labels, silicone coating can improve the peeling performance of the labels, making them easier to stick and remove.
5. Industrial field:
In some industrial products, such as conveyor belts, waterproof rolls, etc., silicone coating can increase the abrasion resistance and slip resistance of the products.
6. Tape industry:
BOPP release film is also widely used in sealing tape and silent tape.
The specific application depends on the type and amount of silicone coating, as well as other properties of the matte film. When selecting and using it, comprehensive considerations should be made based on specific requirements.
