Product introduction

The production of BOPP film is to first make a sheet or thick film from the melt of high molecular polypropylene through a long and narrow head, and then in a special stretching machine, at a certain temperature and a set speed, simultaneously or step by step The film is stretched in two vertical directions (longitudinal and transverse), and after appropriate cooling or heat treatment or special processing (such as corona, coating, etc.).





Introduction to BOPP film

Commonly used BOPP films include: ordinary biaxially oriented polypropylene film, heat-sealable biaxially oriented polypropylene film, cigarette packaging film, biaxially oriented polypropylene pearlescent film, biaxially oriented polypropylene metallized film, matting film, etc.




Advantage

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 film is low, and corona treatment is required before gluing or printing. After corona treatment, BOPP film has good printing adaptability and can be overprinted to obtain exquisite appearance, so it is often used as the surface layer material of composite film.
