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.
Claims17
An article comprising:
- polymeric content comprising:
- a starch-based polymeric material formed from at least a first starch and a plasticizer;
- and
- one or more polyolefins selected from the group consisting of polyethylene, polypropylene, and polystyrene;
- wherein at least 25% of carbon atoms of the one or more polyolefins become at least one of carbon dioxide or methane at about 180 days in simulated landfill conditions or simulated compost conditions;
- wherein the starch-based polymeric material has a crystallinity of less than about 20%, and resists recrystallization, a water content no greater than 2% by weight, and the starch-based polymeric material and one or more polyolefins exhibit a lack of sea-island features when blended together to form the article.
