FILM CAST

Polyamide 6 and high quality copolyamides for cast film extrusion

Cast extrusion is a continuous operation of melting one or several polymers through a die to form a film of between 20 and 200μm that will pass through different rollers with different functions (cooling, finishing, etc.) to finally be wound on a reel.

Promyde^® offers a wide range of polyamide 6 polymers specially designed for cast film extrusion. Our products are suitable for all cast film processing technologies, both in monolayer and multilayer film structures.

Promyde’s PA6 grades have a high barrier to oxygen and other gases, aromas and flavors. They offer thermal stability, thermoformability and compatibility with other materials used in coextrusion and lamination.

Our range of Promyde Polyamide 6 for cast film extrusion offers extremely stable high quality and excellent processing with the lowest moisture and free monomer content in the market.

Solutions

Improved transparency

NUREL has modified PA6 crystallization to offer a range of transparent, strong, and durable materials, ideal for injected parts requiring high transparency.

Barrier solutions

We offer innovative solutions in PA, copolyamides, and barrier materials for food packaging, developed to enhance oxygen barrier properties and extend shelf life.

Sealing films

Polyamides and copolyamides specially developed for films, lids, thermoformed trays, and vacuum bags. We offer low-sealing-temperature copolyamides for optimized packaging performance.

Active packaging

Active packaging technology incorporates active ingredients encapsulated in the polymer to provide antioxidant and antimicrobial properties, extending the shelf life of packaged foods.

Low curling films

This range of copolyamides reduces curling in polyethylene-polyamide coextrusion, thus saving the post-treatment hot water bath.

Antiviral solutions

Applicable to all types of polymers, VI_SAFE minimizes the risk of virus transmission by contact with surfaces.

Recyclable

Thanks to our extensive range of copolyamides and barrier polymers, we provide solutions to achieve the recyclability of mono and multi-material packaging.

Recycled

NUREL provides high-quality recycled materials, from both pre- and post-consumer sources, to reduce environmental impact and reliance on non-renewable resources. Our range includes recycled PA, PP, and PET.

Biobased & Biocircular

NUREL has developed a range of solutions with biosourced and biocircular content to reduce environmental impact and dependence on fossil sources.

BIODEGRADABLE

The new range of biodegradable PA6 is designed to degrade in both aerobic and anaerobic environments, helping to reduce its end-of-life environmental impact.
