High barrier biobased flexible structures for pouches

NatureWorks and Metalvuoto designed high barrier Ingeo based flexible substrates to keep processed foods fresh on store shelves. While Ingeo film has been used for years in fresh food packaging, this is the first application for longer shelf life foods.

The introduction comes in response to a strong interest from the flexible packaging market in packaging simplification, with brands looking to move from complex multi layer laminates to simpler packaging solutions without compromising shelf life.

The new film is said to have barrier properties of less than 0.75 cc/m2/24hr for oxygen and 2.5 g/m2/24hr for water vapor. This provides a significantly better oxygen barrier than metallized biaxially oriented polypropylene (BOPP).
