Abstract

The present invention provides a master batch composition for environmentally degrading conventional plastics including a carrier resin, at least one oxidative degradant, at least one nature biodegradable degradant and at least one foaming agent. The present invention also provides a plastic product which is environmentally degradable at a very low cost versus conventional bio-sourced plastics, and has broad applications for single-use disposable applications or for short-lived products that are discarded within two years of manufacture.
