Oriented polypropylene film

Oriented polypropylene film is made by melting polypropylene resin, casting it into a sheet and then stretching it under controlled heat. This orientation step aligns the polymer chains, which is what gives the film its high clarity, stiffness and strength compared with unstretched polypropylene film. Biaxially oriented grades are stretched in both directions for balanced performance, while the resulting film stays light, moisture resistant and chemically stable. Surface treatment improves ink and adhesive bonding, and coextruded layers can add heat-sealing or matte effects. The film is widely used in packaging, tape, labels and lamination. Custom widths, grades and samples are available on request.
