Ultramid® Flex F – The new copolyamide for packaging offers completely new properties

Wednesday, Apr 26, 2017

Ultramid® Flex F38 L is an entirely new and partly bio-based copolyamide. Thanks to its softness and transparency even at low temperatures and low humidity, this polyamide is ideally suited for soft packaging.

Tear and puncture resistance are also increased in an even softer film.

Films made of Ultramid® Flex F are even soft immediately after processing and without conditioning. This offers huge advantages for film processing at low temperatures and low humidity.

Sustainable packaging solutions
A quarter of the raw material used for the monomer is sourced from regionally-grown rapeseed oil. Ultramid® Flex F38 L supports the trend towards more sustainable packaging solutions. For the packaging industry, the new Ultramid® Flex F unlocks entirely new opportunities for launching bio-based products onto the market.

Enhanced properties open-up new areas of application
With a CO2 and O2 permeability 15 times higher than in conventional polyamide 6, the new Ultramid® Flex F38 L possess considerably changed barrier properties. For example, Ultramid® Flex F is ideally suited for use as cheese ripening bags.

Thanks to its high flexibility and softness, the new Ultramid® can also be used to produce soft vacuum and shrink bags. The product also allows for conventional stretching ratios in deep-drawing processes – without any stress whitening.

In addition to its use in the food industry, the new Ultramid® Flex F is the ideal solution for a wide array of technical films that are characterized by sufficient ductility and tear strength even at lower temperatures.

Processing
Ultramid® Flex F38 L has a considerably higher melt stability than conventional polyamides, allowing for an outstanding bubble stability and higher blow-up ratio. These processing properties enable users to optimize the entire film structure.

BASF at Interpack 2017 in Düsseldorf
