Development of low density polyethylene/sago based biofilm via blow film molding technique

The aim of this study is to develop degradable starch based packaging film with enhanced mechanical properties. A series of low density polyethylene (LDPE)/sago starch compounds with various sago starch contents were prepared by twin screw extrusion with the addition of maleic anhydride grafted poly...
