what is the BOPP film
BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency of.BOPP films with low surface energy, coating or printing before corona treatment. However, the BOPP film after corona treatment, good printing adaptability, can be color printing beautiful appearance, it is usually used as.BOPP surface material films have shortcomings such as easy, no accumulation of electrostatic, heat sealing and so on. In the high-speed operation of the production line, BOPP film is easy to produce static electricity, need to install electrostatic remover. In order to obtain the BOPP heat seal film, can The coating on the surface of BOPP film after corona treatment heat sealing resin glue, such as PVDC latex, EVA latex, or coating solvent glue, coating or extrusion method can be applied to the production of heat sealable coextruded BOPP film. The film is widely used in bread, clothing, footwear and other packaging, and cigarettes. The books cover packaging.
