High resistance films
TIP RESISTANT COPOLIAMIDES FOR RETRACTABLE BAGS AND VACUUM PACKAGING
The packaging of meat foods with bone in multilayer structures has very demanding technical requirements, requiring films with high resistance to tearing and puncture.
NUREL has developed Promyde® BF640 and BF740 that provide excellent tear resistance results, up to three times higher than PA6. Films made with these new copolyamides obtain up to 100% improvement in puncture resistance and have optimum gloss and transparency for vacuum packaging large pieces of bone-in meat.
Promyde BF640 and BF740 are copolyamides suitable for both cast and blown extrusion.
These new copolyamides also performs to manufacture lighter containers, maintaining the mechanical properties of PA6.
Promyde BF640 has high transparency and tear resistance three times higher than standard polyamide.
Promyde BF740 has a puncture and tear resistance twice higher than PA6, maintaining optimal transparency.
