Abstract
Described herein are strength characteristics and biodegradation of articles produced using one or more petrochemical-based polymers and one or more carbohydrate-based polymers. A compatibilizer can optionally be included in the article. In some cases, the article can include a film or bag.
Claims16
An article comprising:
- a starch-based polymeric material formed from a mixture of starches including a first amount of a first starch and a second amount of a second starch;
- and
- a polyolefin-based polymeric material;
- wherein the article has a dart drop impact test value that is greater than:
- (i) a first dart drop impact test value of a first article including the polyolefin-based polymeric material and a first starch-based polymeric material formed from a single starch that is the first starch, and (ii) a second dart drop impact test value of a second article including the polyolefin-based polymeric material and a second starch-based polymeric material formed from a single starch that is the second starch.

A process comprising:
- providing one or more polymeric materials;
- providing one or more starch-based polymeric materials formed from a mixture of starches including a first starch and a second starch;
- mixing the one or more polymeric materials and the one or more starch-based polymeric materials to produce a mixture of materials;
- heating the mixture of materials at a temperature in a range from about 120° C. to about 180° C.;
- and
- producing a film using the mixture of materials, the film having a dart drop impact test value that is greater than:
- (i) a first dart drop impact test value of a first article including the polymeric material and a first starch-based polymeric material formed from a single starch that is the first starch, and (ii) a second dart drop impact test value of a second article including the polymeric material and a second starch-based polymeric material formed from a single starch that is the second starch.
