OPBiaxially-oriented polypropylene (BOPP) film

This is a biaxially-oriented film made from polypropylene (BOPP film). It provides outstanding strength, rigidity, transparency and gloss on top of superior moistureproof properties. We offer a wide range of films with a variety of functions, such as heat sealability, all made possible by the film's multilayer structure. These films are mainly used for food, clothing, household, and personal care products.

Applications

Packaging for rice crackers, snack foods, frozen desserts, instant noodles, frozen foods, processed marine products, fresh vegetables, traditional Japanese sweets and pastries, rice balls, sweet buns, textile products (shirts and underwear), sundry goods, stationery, overwrap for candy boxes, CDs and DVDs, adhesive tape, etc.
