Information

Biaxially oriented polypropylene film is generally a multi-layer co-extruded film, which is obtained by co-extruding polypropylene particles to form a sheet, and then stretching in both vertical and horizontal directions. Due to the orientation of the stretched molecules, this film has good physical stability, mechanical strength, air tightness, high transparency and gloss, toughness and wear resistance, and is a widely used printing film, generally with a thickness of 20 to 40 μm. , the most widely used is 20 μm. The main disadvantage of biaxially oriented polypropylene film is poor heat sealing, so it is generally used as the outer layer of the composite film. Serving dry food. Because the surface of the biaxially oriented polypropylene film is non-polar, high in crystallinity and low in surface free energy, its printing performance is poor, and the adhesion to ink and adhesives is poor. deal with.

Polypropylene film products

Biaxially oriented polypropylene film has the advantages of light weight, 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 property, high impact strength and low temperature resistance. The disadvantage is that the film shrinks easily during heat sealing (except for the heat shrinkable cigarette film which utilizes its heat shrinkability).
