Biaxially Oriented Polyamid Film, abbreviated as BOPA film, is mainly made of polycaprolactam, abbreviated as nylon 6 or PA6. This raw material is melted, extruded, and cast on specialized equipment, and then stretched longitudinally and horizontally (or simultaneously) to form a film, which is called biaxially stretched nylon film.

BOPP plastic film is a very important flexible packaging material. BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness, and good transparency.
