It is made through a process of stretching polypropylene resin in a uniaxial or biaxial direction. Biaxially - oriented polypropylene (BOPP) film is more common.
OPP film has excellent transparency, which means it allows clear viewing of the packaged content. It also has good glossiness, making the packaged products look more attractive. In addition, it has good barrier properties against moisture, which helps to protect the quality of the products inside, such as food, from being affected by humidity. It is widely used in food packaging, tobacco packaging, and label printing and other fields due to its relatively low cost and good performance.
