BOPP film data --
Advantages of BOPP film:
BOPP film is a very important flexible packaging material. BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency.
BOPP film has low surface energy and needs corona treatment before coating or printing. After corona treatment, the BOPP film has good printing adaptability, can be printed in color, and has a beautiful appearance effect, and thus is often used as a surface layer material of the composite film.
Insufficient BOPP film:
BOPP films are also insufficient, such as easy accumulation of static electricity, no heat sealability, and the like. In high-speed production lines, BOPP film is prone to static electricity, and an electrostatic remover is required. In order to obtain a heat-sealable BOPP film, a heat-sealable resin glue such as PVDC latex, EVA latex, etc. may be applied after corona treatment on the surface of the BOPP film, or a solvent glue may be applied, or extrusion coating or The co-extruded composite method produces a heat sealable BOPP film. The film is widely used in the packaging of bread, clothes, shoes and socks, as well as the cover of cigarettes and books. The initial tear strength of the BOPP film is improved after stretching, but the secondary tear strength is very low. Therefore, no cuts can be left on both end faces of the BOPP film, otherwise the BOPP film is easily torn during printing and compounding. BOPP can produce sealing tape after coating self-adhesive, which is a market with a large amount of BOPP.
