The main disadvantage of biaxially oriented polypropylene film is heat sealable poor, it is generally used as the outer layer of the composite film BOPP film, such as polyethylene film composite after moisture resistance, transparency, strength, stiffness and printability compared with ideal for containing dry food. Since the surface of biaxially oriented polypropylene film of a non-polar film, high crystallinity, low surface free energy, and therefore its printing performance is poor, poor adhesion of inks and adhesives for retort food packaging, printing and composite required before the surface treatment. Therefore, printed with ink made of polyvinyl chloride resin. Suitable for bags, book covers and the like. PS film is soft and tough film, clean, colorless and transparent plastic film beverage packaging, when free of plasticizers, the film is always soft, resistant to freezing, storage aging, oxidative polymerization using synthetic binders printing ink blots make good fastness.
