SEALING FILMS

LOW MELTING TEMPERATURE COPOLYAMIDES

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.

POLYAMIDE MONOMATERIAL SOLUTIONS

Promyde^® now offers a new technical solution: Promyde BF745, a sealable copolyamide with a low sealing temperature of 175°C. Promyde BF745 is specially formulated for the production of thermoforming films and vacuum bags for food packaging applications.

With excellent mechanical, optical and barrier properties, it is highly recommended for the manufacture of lighter mono-material polyamide containers.

PROPERTIES OF SEALABLE COPOLYAMIDES

Unsealing capacity at 175°C (26-29 MPa tensile strength)
Thin thicknesses
Suitable for sterilization applications
High transparency
Low curling
Higher gas barrier

WIDE SEALING WINDOW IN COMPOSTABLE BIOPOLYMERS

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

WHAT IS INZEA

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 applications such 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.
