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.
WIDE RANGE OF PA6 FOR EXTRUSION BLOW MOLDING
Promyde has a wide range of viscosities, ranging from 3.3 to 4.0, including different additive packages depending on the needs of the final application. In addition, we offer various products with lubricant, nucleating and slip agents.

Solutions
Barrier solutions
We have two new and innovative food packaging solutions to improve the oxygen barrier and permeability properties of polyamides.
Sealing films
Specially designed for the production of thermoforming films and vacuum bags, Promyde's portfolio includes sealable copolyamide with low sealing temperature.
Low curling films
This range of copolyamides reduces curling in polyethylene-polyamide coextrusion, thus saving the post-treatment hot water bath.
