Biaxially Oriented Polypropylene Film (BOPP Film)

Biaxially Oriented Polypropylene (BOPP) film is a high-performance film material made from polypropylene through a biaxial orientation process (stretched in both machine direction and transverse direction). It appears colorless transparent or white translucent, offering high transparency, high gloss, excellent mechanical strength, and good barrier properties. BOPP film features low density, good heat resistance, high chemical stability, and is non-toxic and odorless. It is widely used in food packaging, printing lamination, adhesive tape, capacitor dielectrics, and other fields. As one of the most widely used plastic films, BOPP film can be used alone or laminated with other materials to create high-barrier packaging.

Main Characteristics :

• Production Process– Manufactured through biaxial orientation (stretched in both machine and transverse directions); molecular chains are oriented, enhancing performance

• Appearance– Colorless transparent or white translucent; high gloss and smooth surface

• Low Density– Density approximately 0.90-0.91 g/cm³; excellent lightweight characteristics

• High Mechanical Strength– High tensile strength, good impact resistance, and strong tear resistance

• Good Barrier Properties– Moderate barrier against water vapor and gases, suitable for general packaging applications

• Good Heat Resistance– Service temperature range from -20°C to 120°C; excellent thermal stability

• High Chemical Stability– Resistant to acids, alkalis, and oils; insoluble in most organic solvents

• Non-Toxic & Odorless– Complies with food contact safety standards; suitable for food packaging

• Good Printability– Surface can be corona-treated for excellent ink adhesion and high color reproduction

• Wide Application– Widely used in food packaging, printing lamination, adhesive tape, capacitor film, and more
