Biopolymers can be produced from many different raw materials. All starch-containing plant products can be used as resources for natural polymer, including corn, potatoes, sunflowers, grain or sugar.
NaKu uses a corn-based starch compound to produce their breathable fresh-storage bags. This corn originates from European agriculture and is GMO-free.
In the manufacturing of our various products made of natural polymer, the technical properties of the material are thoughtfully considered. For instance, the NaKu bottles use a starch-based PLA (lactic acid) as raw material, which is made from particularly from cornstarch which has been shown not to be genetically modified. This is very important to us for all our products.
It is relatively new that NaKu has started using sunflowers as resource to create our office and storefront display cases. The seed husks are used as raw material for natural polymer in an upcycling process. These are a waste product of sunflower oil production.
Many additional substances can be used for producing natural polymers. To further improve the quality and properties of our plastics, additives like oils, resins, cellulose, vitamins, and water are usually infused.
