Most packaging solutions use a combination of different polymers to achieve the necessary technical requirements. In coextrusion, polyamides are used for their mechanical and barrier properties. Polyamide is normally used in combination with polyethylene for its sealing properties. Currently, the packaging industry tends to avoid this type of multi-material combinations as they are not sustainable and cannot be recycled.

Cheese packaging

Cheese packaging is essential to guarantee the quality, safety, and freshness of the product. It must meet a series of requirements to protect the cheese from oxidation, dehydration, and preserve its maturation process. NUREL offers solutions that adapt to these requirements by providing packaging with barrier properties and oxygen permeability.

Promyde offers polyamide 6 with a viscosity of 3.3 with or without lubrication.

Meat and bone-in meat packaging

Packaging for sharp-edged foods requires high puncture resistance, flexibility, moisture barrier, transparency, and an attractive gloss. NUREL offers a range of special copolyamides and polymers with high oxygen barrier properties for the manufacturing of vacuum bags and thermoformed packaging for meat.

Skin Packaging

Skin packaging is gaining popularity due to its lightweight and visually appealing design, as well as its superior technical performance. NUREL provides specially formulated copolyamides that exhibit exceptional strength, sealing capabilities, barrier properties, and unmatched glossiness.

The INZEA® range of biopolymers allows packaging to be sealed over a wide temperature window. This property of INZEA® grades facilitates the design of any sustainable packaging, as no adhesives are required.

Thanks to INZEA’s film sealing solutions, we can obtain multipleapplications that ensure perfect heat sealing without compromising compostability.


Both the more transparent and opaque INZEA grades, and even the paper-like grades, have the ability to seal with each other or with other materials of the same nature.

INZEA offers a wide sealing temperature window that facilitates processing on conventional heat sealing equipment.

Heat sealability and compostability for packaging and pouches

Applications that are a clear example of compostable heat sealing are:

  • Transparent flow packs for fresh products packaging
  • Sealed transparent windows in combination with other materials.
  • Tray liners and heat sealable lids for laminated and thermoformed trays
  • Bags


The world is changing and the plastics industry has to adapt to a new situation where sustainability is a priority for governments, businesses and consumers. INZEA® is our response to our customers’ demand for more sustainable plastic materials.

INZEA is a range of biopolymers which can replace traditional plastics in different applicationssuch as bags, mono-use items and packaging, with the advantage of being biodegradable and compostable.

INZEA product range is obtained from renewable sources and is designed to return to nature by different disposal methodslike industrial & home composting, or by biodegradation in different environments.
