Moisture proof BOPP Film Roll food packaging bags film

BOPP biaxially oriented polypropylene film (BOPP film for short) is a new excellent transparent soft packaging material. It is a crystalline polymer product. After biaxial stretching, due to the role of molecular chains, the crystallinity increases, which significantly improves the tensile strength, elastic modulus, impact strength, tear strength, flexural strength and other properties. It has good transparency, luster, moisture resistance, and also has the advantages of light texture and relatively low price. BOPP film is suitable for all kinds of packaging, printing, composite, aluminum plating, etc.
