SLOW-CRYSTALLISING POLYAMIDE FOR FLEXIBLE FILM APPLICATIONS
PA6 Promyde BF36SC is the latest addition to our high-performance polyamide range.
Specifically developed for applications requiring deep thermoforming, high transparency, and excellent mechanical strength, this grade represents a reliable alternative to conventional PA6 solutions.
This new development delivers enhanced processability for CAST and BLOWN extrusion, offering exceptional flexibility.
Promyde® BF36SC is ideal for sausage casings and vacuum bags, providing higher performance, flexibility, and processability compared to standard PA6 grades.

Aplications
VACUUM PACKAGING BAGS
Polyamide (PA) vacuum bags are extensively used for vacuum-sealing fresh meat, fish, vegetables, cheese and ready-to-eat meals. This packaging solution significantly extends product shelf life by preventing the growth of spoilage-causing microorganisms.
MATERIALS FOR CASING & SMOKED PRODUCT CASING
NUREL offers a specialised range of Promyde PA6 grades, engineered for high-performance casing applications, together with the Enoxite series – an advanced range of ultra-high barrier polymers – designed to preserve the quality and extend the shelf life of cooked meats and sausages.
