The production of BOPP film is to make the melt of high-molecular polypropylene into a sheet or thick film through a long and narrow head, and then in a dedicated stretching machine at a certain temperature and set speed, simultaneously or in steps A film made by stretching in two vertical directions (longitudinal and horizontal) and subject to appropriate cooling or heat treatment or special processing (such as corona, coating, etc.).

BOPP film roll 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 gloss film is low. 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.
