In still another preferred embodiment the biodegradable or bio-renewable material may comprise a blend or mixture of polylactic acid with at least one aliphatic polyester (. polybutylene succinate) or copolyester, a mixture of polylactic acid with at least one polyhydroxy alkanoate (PHA), or a blend of polylactic acid with another biopolymer such as starch, cellulose or another polysaccharide. In a still more preferred embodiment, the biodegradable or bio-renewable thermoplastic material may comprise a mixture of polylactic acid, at least one PHA and at least one starch. In some embodiments, the thermoplastic material may be present in about 5 to about 95% by weight, calculated on the basis of the total weight of the composition. In some embodiments, the amount of polylactic acid, as compared to the total amount of thermoplastic material in the composition, is comprised between approximately 15 to approximately 100% by weight, and, in other embodiments, is comprised between approximately 30 to approximately 100% by weight calculated in relation to the total weight of thermoplastic material.
