Cub Foods tests eco-friendly bags made from crustaceans
Following a model that has worked well for Lund's, Byerly's, Target, and Rainbow Foods, Supervalu Inc.-owned Cub Foods is now focusing on expanding its reusable bag program. Cub says the goals for the program, over the next few years, are to use more recycled material in its bags, make sure the bags are safe through more stringent toxin testing, and reducing the cost of the bags.
The bags are coated in chitosan, which is made by processing chitin, the main structural element in the shells of crustaceans such as shrimp and crabs. Chitosan has many commercial uses, mainly due to the chemical's ability to protect against the growth of fungi and bacteria.
