Preparation of LDPE/ starch/clay nanocomposite films: Investigation the effect of starch amount on printability

The mechanical properties of biopolymer-based food packaging can potentially be enhanced by the use of layered silicates (nanoclay) to produce nanocomposites. In this study, starch/clay. /LDPE nanocomposites were synthesized by a melt extrusion method. Closite 15A were chosen for the nanocomposite preparation. The structures of the hybrids were characterized by X-ray diffraction (XRD). Nanocomposite films showed higher tensile strength and better printability properties. To find the best combinations of starch, the effects of starch content (10, 20, 50 weight% LDPE) were investigated. The mechanical properties and printability of nanocomposite films vary significantly with different starch amount
