Opp bag packing is produced by first making a melt of high molecular weight polypropylene into a sheet or a thick film through a narrow machine head, and then in a dedicated stretching machine at a certain temperature and set speed, simultaneously or in minutes. The film is stretched in two perpendicular directions and subjected to appropriate cooling or heat treatment or processing. The surface energy of the OPP film is relatively low and the adhesion is not strong.

OPP is tasteless, harmless, has high tensile strength, impact strength, good toughness and certain transparency. It can be printed in a color to give a beautiful appearance, so it is often used as a material for composite films.

The OPP film obtained by different processing methods of OPP film has different properties. The opp bag packing produced by the flat film method has a higher tensile ratio than the tubular film method, and the film thickness uniformity is also good.

BOPP can be combined with a variety of different materials to meet specific application needs. For example, BOPP can be combined with LDPE, PE, PT, PO, etc. to obtain high resistance to gas, moisture, transparency, high temperature and low temperature.
