Copolyamides to improve O2 barrier and CO2 permeability

Polyamides are used on the packaging industy for their mechanical properties, such as tear and puncture resistance; and barrier advantages. NUREL, is now introducing two new breakingthough solutions to modify the barrier properties of polyamides. Promyde BF740 is a new developped copolyamide to improve oxygen barrier and Promyde BF640 formulated with an enhanced CO2 permeability.

Promyde BF740 has been specifically designed for packaging solutions that require oxygen barrier to preserve food. By using BF740 the polyamide layer thickness will be reduced mantaining oxygen permeability, in some appliactions EVOH use can be avoided,  resulting in lighter and more cost efficient packagings. Unlike traditional polyamides, BF740 preserves its oxygen barrier even under high environmental humidity conditions,  being a highly valued solution for containers that undergo sterilization processes or that are destined to high humidity geographical areas.

Promyde BF640 is the material of choice for premium mature cheese packaging that support product’s ripening process. Thanks to its modified CO2 permeability, films made of our copolyamide BF640 allows the release of maturing cheese gasses.
