Metallised cellulose-based material has been customised to allow Boulder Canyon Natural Foods, a North American snack food manufacturer, to launch the new sustainable packets, which are compostable in six weeks, according to Innovia Films.

They are being sold in US retail outlets and Innovia said it worked in conjunction with Canadian packaging converter group Genpak to ensure its NatureFlex NKM could be utilized with this type of food product.

Steve Sklar, senior vice president of marketing for Boulder Canyon, said the new bags for its All Natural Kettle Cooked Potato Chips line allows the snack maker to set a positive example for the industry as well as "educating consumers on key issues and enabling them to play a role in improving the environment by diverting waste away from landfills."

Zena Bergmann, a spokesperson for Innovia, told FoodProductionDaily.com that this is the first time the NKM material has been incorporated into crisp packaging.

She said that Genpak spearheaded the research and development of the bag, with Innovia supplying the film used in the structure.
