Abstract
Provided herein are starch compositions, which comprise a first starch having a first weight average molecular weight between about 300,000 and about 4,000,000 Daltons, a second starch having a second weight average molecular weight between about 1,000 and about 290,000 Daltons, and a water-soluble polymer. Also provide herein are articles of manufacture and films comprising the starch composition, and methods of making the starch composition.
Claims19
A starch composition comprising:
- a. from about 60% to about 99% by weight of a first starch, said first starch comprising one or more of unmodified starch and modified starch, said first starch having a first weight average molecular weight between about 300,000 and about 4,000,000 Daltons;
- b. from about 0.1% to about 40% by weight of a second starch, said second starch comprising one or more of unmodified and modified starch, said second starch having a second weight average molecular weight between about 1,000 and about 290,000 Daltons;
- and
- c. from about 0.5% to about 40% by weight of at least one water soluble polymer comprising one or more of polyvinyl alcohol, polyvinyl acetate and polyoxyalkylene,
- wherein the molecular weight distribution of the starch composition is greater than 6.5.
