Production of BOPP film is made from polypropylene polymer melt through the long and narrow nose first sheet or thick film, and then within the special drawing machine, under certain temperature and the set speed, at the same time two or step by step in the vertical direction (vertical, horizontal) on the drawing, and through the appropriate cooling or heat treatment or special processing (such as corona, coating, etc.) made of thin film.
BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, strength and toughness and good transparency. BOPP atomized release film is used to produce insulation board.
BOPP film has low surface energy and needs corona treatment before gluing or printing. After corona treatment, BOPP film has good printing adaptability, can be color printing and get beautiful appearance effect, so it is often used as the surface material of composite film.
