NEW COPOLYAMIDES FOR ASYMMETRICAL MULTILAYER FILM
Curling is a common problem in asymmetrical PA/PE film extrusions for the manufacture of vacuum bag and container lids. Curled films have difficulty being wound, printed or thermoformed correctly.
The curling issues arise from a temperature solidification difference between polyamide (PA) and polyethylene (PE). This problem can be mitigated with our range of copolyamides for asymmetrical multilayer structures.
Variety of promyde copolyamides
Promyde BF940 is the reference copolyamide on the market. It is an alternative to copolyamide 6/66 that stands out for eliminating curling and for its high transparency. In addition, NUREL offers a new range of copolyamides such as Promyde BF640, BF740 and BF745 that also achieve low curling results and high transparency.
ADVANTAGES OF PROMYDE FOR LOW CURLING FILMS
By using our Promyde copolyamides in the production of PA/PE multilayer films, the temperature solidification difference is minimized, reducing the occurrence of curling. This ensures that these structures can be efficiently processed, accurately printed, and thermoformed smoothly, resulting in high-quality final products.

Applications
Meat and bone-in meat packaging
Packaging for sharp-edged foods requires high puncture resistance, flexibility, moisture barrier, transparency, and an attractive gloss. NUREL offers a range of special copolyamides and polymers with high oxygen barrier properties for the manufacturing of vacuum bags and thermoformed packaging for meat.
Skin Packaging
Skin packaging is gaining popularity due to its lightweight and visually appealing design, as well as its superior technical performance. NUREL provides specially formulated copolyamides that exhibit exceptional strength, sealing capabilities, barrier properties, and unmatched glossiness.
Stand-up pouches
NUREL offers a complete range of Polyamide 6, Copolyamides and Ultra-High barrier materials for Doypacks. PA-based film materials not only help extend the shelf life of packaged food but also contribute to reducing plastic usage. Promyde polyamides offer excellent mechanical and barrier properties while providing an appealing packaging finish, thanks to their glossy appearance.
Cheese packaging
Cheese packaging is essential to guarantee the quality, safety, and freshness of the product. It must meet a series of requirements to protect the cheese from oxidation, dehydration, and preserve its maturation process. NUREL offers solutions that adapt to these requirements by providing packaging with barrier properties and oxygen permeability.
Deep thermoforming
Deep thermoformed packaging is extensively utilized nowadays due to its numerous benefits, including lightweight, transparency, and gas barrier properties, necessitating the use of materials with high technical performance for its production.
