                    BOPP Film

                    Biaxially oriented polypropylene film (BOPP) is generally a multi-layer co-extruded film. It is made by co-extruding polypropylene particles into a sheet and then stretching it in both longitudinal and transverse directions. Due to the orientation of the stretched molecules, this film has good physical stability, mechanical strength, air tightness, high transparency and gloss, and is tough and wear-resistant. It is a widely used printing film, and its thickness is generally 20 to 40 μm. , the most widely used is 20 μm. The main disadvantage of biaxially oriented polypropylene film is poor heat sealability, so it is generally used as the outer film of composite films. For example, after compounding with polyethylene film, its moisture resistance, transparency, strength, stiffness and printability are all better, and it is suitable for Contains dry food. Since the surface of the biaxially oriented polypropylene film is non-polar, has high crystallinity and low surface free energy, its printing performance is poor and its adhesion to inks and adhesives is poor. Surface treatment is required before printing and lamination. deal with.

                    Product Features:

                    Biaxially oriented polypropylene film [1] has the advantages of being lightweight, non-toxic, odorless, moisture-proof, high mechanical strength, good dimensional stability, good printing performance, and good transparency. It has the advantages of high transparency, good gloss, good barrier properties, high impact strength, and low temperature resistance.

                    Its comprehensive performance is better than moisture-proof

                    Cellophane, polyethylene (PE) film, PET film. BOPP film also has excellent printing effects. The representative physical property data are: turbidity <1.5%; gloss>85%; tensile strength (longitudinal/transverse)>120/200MPa; elongation at break (longitudinal/transverse) <180%/65%; elastic modulus It is 1700~2500Mpa; the embrittlement temperature is -50℃.

                    product advantages:

                    High tensile strength, good barrier properties and high transparency.

                    Due to the orientation of molecules, the crystallinity is increased, the tensile strength, impact strength, rigidity, toughness, moisture resistance, and transparency are all improved, and the cold resistance of the film is also improved.

                    Has good gas barrier and moisture resistance

                    High transparency, good gloss and good printability

                    Non-toxic, odorless and tasteless, can be used directly in situations in contact with food and medicines
