Abstract

This invention relates to biopolymer-based compositions and biopolymer-based formed bodies such as film, sheet, capsule, casing or coating-film or spray thereof. In another embodiment, the invention relates to a process for producing a biopolymer-based starting material and biopolymer-based formed bodies such as cited above, for the manufacture of pharmaceutical, veterinary, food for cosmetic products.

Description

technical field [0001] The present invention relates to biopolymer-based compositions as well as biopolymer-based formed bodies thereof, such as films, flakes, capsules, films or sprays for packaging or coating. In another embodiment, the invention relates to a method for producing biopolymer-based starting materials and biopolymer-based shaped bodies as described above for pharmaceutical products, veterinary products, food Manufacture of products, cosmetic or otherwise, more specifically films for enclosing foods, jellies or jellies (preferably for pre-dosed preparations), such as soft or hard capsules, based on The starting material of the biopolymer comprises a biopolymer or a mixture of biopolymers, preferably selected from polysaccharides from bacteria (such as pullulan, soligel(R) or dextran) and / or polysaccharides from plants (such as starch, starch derivatives, maltodextrin or cellulose derivatives). Background of the invention [0002] One of the most preferred ed...
