Biaxially oriented polypropylene BOPP is a plastic film whose main material is polypropylene resin. In terms of manufacturing process, BOPP adopts biaxial stretching technology, firstly, the polypropylene raw material is melted and extruded into a thick sheet, and then stretched at a high ratio in both the longitudinal and transverse directions (usually 3-10 times in the longitudinal direction and 6-12 times in the transverse direction), so that the molecular chain is oriented along the stretching direction, thereby improving the mechanical properties of the film.
