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.
Claims16
A resin adapted for forming a biodegradable container having a body and a closure therefor, the resin comprising:
- from about 0.1 to about 10 weight percent of at least one nucleating agent;
- from about 0.05 to about 3 weight percent of at least one melt strength enhancer;
- and
- 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 monomeric units wherein R1 ═CH3 comprise 75 to 99 mol percent of the polymer.
