POLYAMIDE 6 AND COPOLYAMIDES FOR BOPA FILM PRODUCTION
Biaxially oriented polyamide films (BOPA) are very thin structures that provide a high barrier and excellent mechanical properties (puncture and tear resistance).
Promyde® offers a wide range of polymers to suit all BOPA film processing technologies for both simultaneous and sequential orientation equipment.
Polyamide 6 is used in food packaging due to its high barrier to oxygen and other gases, in addition to avoiding contamination of aromas and flavors. BOPA extrusion grades of Promyde offer thermal stability and compatibility with other materials used in lamination.
With our range of products specially designed for BOPA extrusion, we offer high quality and excellent processing with the lowest moisture and free monomer contents in the market.
This process is especially recommended for the packaging of frozen products, tray lids and vacuum packaging bags.
PROMYDE PA6 FOR BOPA EXTRUSION
Promyde offers polyamide 6 with a viscosity of 3.3 with or without lubrication. For sequentially oriented equipment, it is recommended to use the lubricated grade.
SPECIFIC PROPERTIES FOR BOPA FILM
- Low moisture content & monomer
- Improved gas barrier (O2, CO2,…) aromas and chemicals.
- Availability of grades with increased CO2 permeability.
- Good optical properties, extremely transparent grades
- Special grades with sealing properties.
- High temperature HT resistance, available for sterilization treatments.

Solutions
Barrier solutions
We have two new and innovative food packaging solutions to improve the oxygen barrier and permeability properties of polyamides.
Sealing films
Specially designed for the production of thermoforming films and vacuum bags, Promyde's portfolio includes sealable copolyamide with low sealing temperature.
Low curling films
This range of copolyamides reduces curling in polyethylene-polyamide coextrusion, thus saving the post-treatment hot water bath.
