Biaxially oriented polyamide film (BOPA)
BOPA film meets nearly all expectations of modern and future first class applications, whether food or non food.
Main features: |  | Maximum tensile, impact and piercing strength
| | | High flex-/stress-crack and puncture resistance
| | | Barrier to gases (oxygen, nitrogen, carbon dioxide) and flavours/odors
| | | High resistance to oil, greases, hydrocarbons, chemicals
| | | Easy thermoformability
| | | Excellent haze and gloss for cast and blown film
| | | Optimal printability
| | | Wide applicable temperature range
| | | Easy laminating with other films |
Therefore BOPA film is used for the packaging of sensible frozen and cooked foods, pickled vegetables, agricultural and aquatic products or distilled goods packaging. Other main applications are in the medical sector: blood bottles, infusion bags etc. BOPA film is also used for electrical industrial materials packaging and for some "exotic" applications like so called "designer-balloons".
The favourite raw material out of the big PA family is PA 6. It is least costly of the polyamides and offers best gas and aroma barrier, improved strength against flex-crack, abrasion, impact and poke puncture, good tearing properties for opening packages as well as mechanical strength, essential to printing and lamination processes.
