Biaxially oriented polypropylene film has the advantages of light weight, non-toxic, odorless, moisture-proof, high mechanical strength, good dimensional stability, good printing performance, and good transparency. It has the advantages of high transparency, good gloss, good barrier property, high impact strength and low temperature resistance. Its disadvantage is that it is easy to shrink the film during heat sealing (except for the heat shrinkable cigarette film using its heat shrinkability). Its overall performance is superior to that of moisture-proof cellophane, polyethylene (PE) film, and PET film. BOPP film also has excellent printing effect. Disadvantages: The elongation rate is lower than that of PP, and the heat sealing performance is poor. It is not easy to seal when used independently. When used, it is generally combined with PE and other films with good heat sealing properties.
Advantages: high tensile strength, good barrier performance, high transparency. Due to the orientation of molecules, the degree of crystallinity increases, the tensile strength, impact strength, rigidity, toughness, moisture resistance, and transparency are all improved, and the cold resistance of the film is also improved. It has good gas barrier and moisture resistance; high transparency, good gloss, and good printability; non-toxic, odorless, tasteless, and can be directly used in occasions in contact with food and medicine.
