Product Description

BOPP Film Cigarette Box Wrapping High Shrinkage And Transparency Application:
BOPP is the abbreviation of "Biaxially Oriented Polypropylene", which is biaxially stretched polypropylene film. BOPP film is a functional film product that uses BOPP as the base material, coated with acrylic glue on one side and laminated with a release film (single-layer non-laminated release film).

Its production is to make the melt of high molecular polypropylene through the narrow head first to make a sheet or thick film, and then in a special drawing machine, at a certain temperature and set speed, at the same time or step by step Films made by stretching in two vertical directions (longitudinal and transverse), and after proper cooling or heat treatment or special processing (such as corona, coating, etc.).

BOPP film is a very important flexible packaging material. BOPP film is colorless, odorless, odorless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency. The surface energy of BOPP protective film is low, and corona treatment is required before gluing or printing. After corona treatment, BOPP film has good printing adaptability, and can be printed in color to get exquisite appearance effect, so it is often used as the surface layer material of composite film.
