BOPP film is a very important flexible packaging material, which is widely used. The surface energy of BOPP film is low, so corona treatment is needed before gluing or printing. After corona treatment, it has good printing adaptability, and can be printed in color to get beautiful appearance, so it is often used as the surface material of composite film.

in order to obtain the heat-sealable BOPP film, the surface of BOPP film can be coated with heat-sealable resin glue, such as PVDC latex and EVA latex, or coated with solvent glue, and the heat-sealable BOPP film can be produced by extrusion coating or extrusion compounding. The film is widely used in the packaging of bread, clothes, shoes and socks, as well as the cover packaging of cigarettes and books.

the initial tear strength of BOPP film is improved after stretching, but the secondary tear strength is very low. Therefore, there should be no notches on both ends of BOPP film, otherwise the BOPP film is easy to tear when printing and laminating.

BOPP can be coated with self-adhesive to produce sealing tape, which is a market with a large amount of BOPP.
