Composition comprising biopolymer

A composition comprising or produced from a biopolymer, an olefin copolymer, and an optional polymer wherein

• the biopolymer includes a hydroxyalkyl-modified starch and is present in the composition in a concentration of about 85% or more, based on the total dry weight of the composition;
• the olefin copolymer is produced by copolymerization of an olefin, a monomer, and optionally a comonomer;
• the olefin includes ethylene, propylene, butylene, or combinations of two or more thereof;
• the monomer includes maleic anhydride, maleic acid, salt of maleic acid, maleic acid diester, maleic acid monoester, itaconic acid, fumaric acid, fumaric acid monoester, or combinations of two or more thereof;
• the optional comonomer includes (meth)acrylic acid, salt of (meth)acrylic acid, C1-C8 ester of (meth)acrylic acid, carbon monoxide, sulfur dioxide, acrylonitrile, glycidyl acrylate, glycidyl methacrylate, and glycidyl vinyl ether, or combinations of two or more thereof;
• and
• the optional polymer includes ethylene copolymer, polyvinyl butyral copolymer, or combinations thereof;
• the ethylene copolymer includes ethylene alkyl(meth)acrylate copolymer, ethylene vinyl acetate copolymer, ethylene acid copolymer or ionomer thereof, poly(vinyl alcohol), poly(hydroxyalkanoic acid), polyester, polyamide, polyurethane, polyolefin, polycaprolactone, copolyetherester, polyalkylene oxide, or combinations of two or more thereof.
