What is the difference of BOPP Film BOPET Film BOPA Film?

  BOPP Film,BOPET Film and BOPA Film are very common material for flexible packagings. But they have different properties and used for different applications.

1-BOPP film:  

BOPP films (Biaxially Oriented PolyPropylene Films) are produced by stretching polypropylene film in both machine direction and transverse direction. BOPP film is used in vast range of applications comprising packaging, labeling and lamination. BOPP Films are preferred substrate for food packaging globally because of its inherent moisture barrier properties, seal ability, high clarity and graphic reproduction and shelf appeal, best possibilities of the pack being a mono layer/homogeneous structure.

2-BOPET Film

  PET Film is a polyester film made from orientated polyethylene terephthalate (PET). BOPET is used because of its high tensile strength, chemical and dimensional stability, transparency, reflectivity, gas and aroma barrier properties and electrical insulation

3–BOPA Film

  Biaxially oriented nylon film (BOPA), has excellent characteristics, can be used for a variety of high-grade packaging. BOPA has a very high tensile strength, anti-puncture strength, excellent flexibility, resistance,
