Investigation of Mechanical & Antimicrobial Properties Biodegradable Nanocomposites LDPE/Starch

Application of biodegradable polymers includes disposable food service items food packaging, packaging foams and agricultural mulch film. Increasing public concern over dwindling landfill space and accumulation of surface litter has promoted the developed of degradable plastics [1]. ]. Starch is an appropriate material as degradable filler because it is cheap and can improve degradability. However, the addition of starch to plastic weakness the mechanical properties of composites. Therefore, it is necessary to added of materials to improve mechanical properties such as nanoparticles. In this work composites of low density polyethylene (LDPE)/starch biopolymer were been blend with clay. Nanoclay was added to improve the interfacial strength of LDPE/starch blends by exploiting the concept of nanocomposites [2,3], also clay have antimicrobial properties This article describes the effect of clay on the in biodegradable composites (LDPE/starch biopolymer) such as mechanical properties [4].
