The LACTIPS Company, a startup installed in the Rhône -Alpes (France), has patented a bioplastic using milk as raw material (based on casein being the milk protein). The manufacturer of this bioplastic indicates that this product is biodegradable, bio-based, water soluble and edible (packaging could then be incorporated into the recipe of the finished product, it would be for example tea bags, bags of chocolate, sugar or syrup).
In the food market, this new technology would replace some of the packaging making use previously of bisphenol A, particularly substitution of metal containers in which the metal was covered with a resin that may contain BPA (preparations for early childhood as powdered milk and baby food, cans and syrups...). Different applications of these packaging are being developed.
