LOW MELTING TEMPERATURE COPOLYAMIDES
Most packaging solutions use a combination of different polymers to achieve the necessary technical requirements. In coextrusion, polyamides are used for their mechanical and barrier properties. Polyamide is normally used in combination with polyethylene for its sealing properties. Currently, the packaging industry tends to avoid this type of multi-material combinations as they are not sustainable and cannot be recycled.
POLYAMIDE MONOMATERIAL SOLUTIONS
Promyde® now offers a new technical solution: Promyde BF745, a sealable copolyamide with a low sealing temperature of 175°C. Promyde BF745 is specially formulated for the production of thermoforming films and vacuum bags for food packaging applications.
With excellent mechanical, optical and barrier properties, it is highly recommended for the manufacture of lighter mono-material polyamide containers.
PROPERTIES OF SEALABLE COPOLYAMIDES
- Unsealing capacity at 175°C (26-29 MPa tensile strength)
- Thin thicknesses
- Suitable for sterilization applications
- High transparency
- Low curling
- Higher gas barrier

Applications
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.
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.
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.
