What is the difference between OPP film and PE film?

Both are plastic, but the material is different, PE is polyethylene, OPP is polypropylene.

OPP film is oriented tensile polypropylene film. Is the polymer polypropylene melt is first made into sheet or thick film, at a certain temperature and set speed, in the vertical two directions of stretching, and through special processing made of film.

PE film is a thermoplastic resin film prepared by ethylene polymerization. Polyethylene film odorless, non-toxic, feel like wax, has excellent low temperature resistance, good chemical stability, resistance to most acid and alkali erosion, low water absorption, good electrical insulation performance.
