BOPP protective film is one of the flexible packaging materials. BOPP protective film is a plastic film made of BOPP as the base material, coated with acrylic glue on one side and bonded with a release film (single layer without a release film). BOPP plastic film Smooth surface, high transparency, good temperature and weather resistance. The OPP protective film is a plastic film made of OPP as the base material, coated with acrylic glue on one side and attached to the release film (single layer without the release film). The surface of the OPP plastic film is smooth, transparent, and temperature resistant. Good weather resistance, OPP plastic film surface is smooth, high transparency, good temperature and weather resistance.

Both BOPP and OPP are a kind of polypropylene film, in which BOPP is a biaxially oriented polypropylene film, and OPP is a uniaxially oriented polypropylene film. Compared with OPP, BOPP has the following characteristics: better heat resistance. Since BOPP is biaxially stretched, its molecular structure is tighter, so it has better heat resistance and is suitable for use in high temperature environments. Greater transparency. The two-way stretching of BOPP makes it more transparent and better in appearance, and is suitable for packaging of high-end products. Higher strength. The two-way stretch of BOPP makes it stronger and less prone to tearing, and is suitable for some product packaging that requires good protection. The difference between BOPP and OPP lies in the different stretching methods, so there are differences in some properties. It is necessary to select a suitable polypropylene film for packaging according to the actual situation.
