Binding agent for biodegradable compression molded rice straw filled rice bran packaging products
Rice bran (RB) has been used as a natural fibre in polyolefin which results in lower mechanical properties and low interfacial adhesion that need a coupling agent or binder at higher loading. Rice bran (RB) and rice straw (RS) which both is low cost materials were developed in the processing of biod...
