摘要: A polymer composition and its use for thin film packaging applications including on a dry basis: a) from 45 to 90% by weight of starch; b) from 0.1 to 15% by weight of a water soluble polymer selected from polyvinyl alcohol, polyvinylacetate, and copolymers of ethylene and vinyl alcohol which have a melting point compatible with the molten state of the starch component; and c) from 5 to 45% by weight of one or more plasticizers having a molecular weight in the range of 50-6000, more preferably 50-2500 and more preferably still 100-400 and desirably selected from the group consisting of sorbitol, glycerol, maltitol, xylitol, mannitol, erythritol, glycerol trioleate, tributyl citrate, acetyl tri-ethyl citrate, glyceryl triacetate, 2,2,4-trimethyl-1,3-pentanediol diisobutyrate, polyethylene oxide, ethylene glycol, diethylene glycol or polyethylene glycol.
