Features
Biaxially-oriented PA film is called BOPA film for short. Its raw material is polycaprolaciam know as nylon 6 or PA6. The material is melt in the special equipment and extruded out and made into film through stretching vertically and horizontally,that is biaxially-oriented PA film.

Production features
●Perfect for high-quality printing (one step film is better for high speed multicolor printing) 
●Excellent anti-stretching intensity, anti-striking and anti-threading 
●High prevention from smell and gas 
●Anti-lipid carbon oxide 
●Wide suitable temperature range (-60℃~150℃)esp. refrigerant package, vacuum package and retort pouch (one step film better for retort packaging) 
●Good transmittance and gloss

Application
Because of the good speciality of BOPA film, it is widely used into industry, agriculture, food freshening and medicine package etc. Actually, it is hardly to use this film only. Normally it is laminated with other materials ( such as PE, EVA, PET, CPP aluminum foil and paper etc.) in order to get better comprehensive performance. After being laminated, they can be used into these fields: (1) Food package: vacuum refrigeration and vacuum retort package (ham, chicken, sausage and other flesh food), spice, salty food (pickles), axunge food, sea plant food, vegetable, tea and flavor etc. (2) Non-food package: disinfected medical appliance, cosmetics, scour, shampoo, integrated circuit and some other instrument.
