News - Multilayer barrier film

Advances in barrier films have sparked a revolution in food packaging. Multilayer barrier film packaging keeps flavors inside and outside the package and provides a barrier to oxygen or other gases or moisture to ensure shelf life.

APG can help design coextruded films of up to 12 layers to achieve the specific barrier and properties best suited to your application. The exact structure starts with proper resin selection to balance all the performance characteristics of EVOH, nylon, polyethylene, polypropylene and many other polymers. We offer custom films for nitrogen modified atmosphere, vacuum packaging or any other available packaging technology. Multilayer films can also be designed for applications requiring very high mechanical strength. With the expertise to develop the films required for the latest packaging innovations, we look at new trends in packaging solutions.

Application example

Barrier packaging applications include vacuum bags, modified atmosphere, pet food, and more.

Air-cooled – 9 layers

– Intermediate barrier film:

– PA/PA/PE(PP)

– PE/PA/PE(PP)

– High barrier film:

– PE/EVOH/PE

– PE/PA/EVOH/PA/PE

– PA/PA/EVOH/PA/PE

Multilayer AIR-COOLED Films (Blown Films): They are available in 7-9-12 layers. This type of film is best suited for symmetrical structures that require high mechanical properties along with moderate or high barrier properties.

These films are 50 to 250 microns thick and 30 to 2,200 mm wide.
