Ultramid^® Flex F38

Ultramid^® Flex F38 is a bio-based copolyamide and represents BASF’s contribution to a potential sustainable packaging strategy. About one-third of the raw materials for the monomer come from locally grown rapeseed oil. Ultramid^® Flex F38 impresses with both its performance and its processing properties.

Manufacturers of shrink films and vacuum packaging for food applications can benefit from Ultramid^® Flex F38’s outstanding mechanical properties across a wide temperature range. In addition, Ultramid® Flex F38 promises high stretch and tear resistance – even at low temperatures.  

15 times more permeable to CO₂ and O₂ than conventional polyamide 6, this Ultramid has significantly modified barrier properties. This can be an advantage for food applications that involve a release of gases, such as in cheese ripening bags.

Ultramid^® Flex F38 is characterized by outstanding bubble stability and a high blow-up ratio in blown film extrusion. The product impresses with its excellent processing stability, even in cast applications. Together, the processing properties of Ultramid^® Flex F38 help to optimize the entire film structure in multilayer films.

Films made from Ultramid^® Flex F38 are soft immediately after processing, without conditioning. This offers huge advantages for the subsequent further processing of the film roll.
