BOPP

BOPP resin is the polypropylene (PP) resin used as the raw material to manufacture biaxially oriented polypropylene (BOPP) film. This process involves melting PP resin pellets, extruding them into a sheet, and then stretching the film in two perpendicular directions (biaxial orientation). The biaxial stretching improves the film's mechanical strength, clarity, and durability, making it a popular choice for flexible packaging, labels, and tapes.
