Abstract
A polymer composition containing cellulose acetate in combination with one or more bloom resistant or bio-based plasticizers and optionally one or more bio-based polymers is described. The polymer composition is formulated so as to have properties similar to petroleum-based polymers for producing, for example, single-use biodegradable articles.
