POLYVINYL ALCOHOL COMPOSITIONS

摘要

The invention concerns polyvinyl alcohol (PVA) compositions for the use in pharmaceutical, veterinary, food, cosmetic or other products like films for wrapping food, aspics or jellies, preferably for predosed formulations like soft or hard capsules. Compared with hard gelatine capsules (HGC) capsule films consisting of PVA have extremely low water vapour permeability and much lower water content.
