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
â—Perfect for high-quality printing (one step film is better for
high speed multicolor printing)
â—Excellent anti-stretching intensity, anti-striking and
anti-threading
â—High prevention from smell and gas
â—Anti-lipid carbon oxide
â—Wide suitable temperature range (**0℃~**0℃)esp. refrigerant
package, vacuum package and retort pouch (one step film better for
retort packaging)
â—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.

Notices for transportation and
storage:
Take care during transportation in order to prevent collision,
sunshine and rainfall.
The production should be stored in the clean and dry storage. Make
it in good arrangement in order not to be out of shape or damaged
by outside pressure. Keep the distance to the hot object in 2m at
least. Storage expiry can not be more than half a year.
