Physico-mechanical, and Biodegradation Properties of Polyethylene/Food Polysaccharide Blends
Abstract: Hydrophilic/polar and hydrophobic/non-polar materials do not blend well, which causes issues in the production of biodegradable plastic. Plasticizer (glycerol) was one of the components added to the mixture to increase compatibility between the two materials; this also made the film less brittle. The purpose of this study is to look at how different food polysaccharide contents affect the physico-mechanical, and biodegradation characteristics of novel polymeric-based bio-composite films made from low-density …
