McCain has produced a biodegradable freezer bag that's 100% compostable. This bag is an exclusive and sustainable bag only available in Europe and is said to be the first multi-layer film to be made from renewable sources. McCain uses a ‘FKuR’ resin to create the bag for frozen fries.

The FKuR Bio-Flex resin has been available in Europe for a long time, but only recently introduced to non-European markets. This bag presents a sustainable alternative to plastic and a revolutionary discovery for food storage as well. Other companies are also following this discovery in hopes to benefit the current market by using renewable sources.

The fact that bio-plastic can be used in a multi-layered system makes this material more versatile.
