Polyamide 6 for blown film extrusion

Blown film extrusion is the continuous process of casting one or more polymers in a circular die to form a hollow tube. This tube expands with air, cools and flattens, and finally coils up.

Promyde® offers a wide range of polyamide 6 polymers specially designed for blown film extrusion. Our products are suitable for all blown film processing technologies, both in monolayer and multilayer film structures and with air or water cooling systems.

NUREL’s polyamide 6 has high barrier properties, offering thermal stability and high compatibility with other materials used in coextrusion and lamination.

Promyde has developed a range of polyamides for extrusion blow film that offers high quality standards with simple processing due to its low moisture and monomer content.
