Plastic bags made from OPP film, featuring a built-in adhesive strip for easy peel-and-seal closure.

The OPP flat pocket bag is a packaging solution manufactured from bidirectional stretch polypropylene (OPP) film as the core material, processed through cutting and heat sealing techniques to achieve a flat bag body with a straight opening.

The OPP inverted-sealed self-adhesive bag is primarily made from biaxially oriented polypropylene (OPP) film, combining an inverted-sealed structure with self-adhesive strips to form the packaging bag.
