BASF presents new Ultramid® copolyamide for film and monofilament applications

As of now, BASF offers a new, high-quality Ultramid® for film and monofilament applications such as fishing lines with Ultramid® C37LC. Ultramid® C37LC is a PA6/6.6 copolyamide. It allows manufacturers of shrink film for food packaging to achieve higher hot water and hot air shrinking. The manufacturer can thus forgo the otherwise usual admixture of amorphous polyamides, which makes the production process leaner and more efficient.

The improved properties of the product also avoid undesired curling of asymmetrical multi-layer films with polyethylene or polypropylene. These films are used for stand-up pouches, lid films and deep drawing applications, among others. By reducing the melting point of the Ultramid® to 182°C, the usual effort for post-treatment in form of a water bath or the admixture of amorphous polyamides can be omitted.
Films produced with Ultramid® C37LC have a low crystallinity and are therefore significantly softer and more transparent than films made of conventional copolyamide.
