Abstract: A biodegradable preform, biodegradable containers and a method for making the plastic containers. The biodegradable container wherein the body of the container includes from about 40 to about 99 weight percent of a polymer derived from random monomeric repeating units having a structure of wherein R1 is selected from the group consisting of CH3 and a C3 to C19 alkyl group. The monomeric units wherein R1 is CH3 is about 75 to about 99 mol percent of the polymer. A resin adapted for forming the container is also disclosed.

Abstract: A preform for a biodegradable container wherein the preform includes from about 40 to about 99 weight percent of a polymer derived from random monomeric repeating units having a structure of wherein R1 is selected from the group consisting of CH3 and a C3 to C19 alkyl group, wherein the polymer comprises from about 20 to about 99 wt. % of the preform and wherein the monomeric units wherein R1=CH3 comprise 75 to 99 mol percent of the polymer and wherein the preform has a body having a uniform wall thickness throughout the body of the preform. A resin adapted for forming the preform is also disclosed.

Abstract: A biodegradable label and a method for making the label. The biodegradable label includes from about 40 to about 99 weight percent of a polymer derived from random monomeric repeating units having a structure of wherein R1 is selected from the group consisting of CH3 and a C3 to C19 alkyl group. The monomeric units having R1?CH3 is about 75 to about 99 mol percent of the polymer. A resin adapted for forming the label is also disclosed.

Abstract: A biodegradable container closure and a method for making the container closure. The biodegradable container closure includes from about 40 to about 99 weight percent of a polymer derived from random monomeric repeating units having a structure of wherein R1 is selected from the group consisting of CH3 and a C3 to C19 alkyl group. The monomeric units having R1?CH3 is about 75 to about 99 mol percent of the polymer. A resin adapted for forming the closure is also disclosed.

Abstract: A polyester is disclosed which is made up of: (1) from about 15 to about 40 weight percent monomer repeat units of isosorbide; (2) from about 25 to about 60 weight percent monomer repeat units of a dicarboxylic acid or anhydride such as succinic acid or anhydride; and (3) from about 10 to about 20 weight percent monomer repeat units of a polyhydric alcohol such as 1,3-propanediol. In some instances, the polymer may also include monomer repeat units of methyl nadic anhydride or nadic anhydride. A polymer composition is also disclosed, which includes the polyester as well as a biodegradable polymer selected from the group consisting of poly(lactic acid), poly(hydroxyalkanoates), and mixtures thereof.

Abstract: A biodegradable aqueous dispersion is disclosed, which is made up of from about 35 to about 75 weight percent water and from about 25 to about 65 weight percent of polyhydroxyalkanoates. Also disclosed is a biodegradable food service item, which includes a biodegradable substrate having at least one food contact surface. A coating is applied over the at least one food contact surface, which is formed from the biodegradable aqueous dispersion.
