EVA is another widely applied ethylene copolymer. With increasing vinyl acetate (VA) content, EVA copolymers change from a semi-crystalline thermoplastic material (LDPE) into a rubber and again into an amorphous thermoplastic material (PVAc). It is known that PLA is miscible with poly(vinyl acetate) (PVAc) [24,25] while shows clear phase separation when it is blended with PE [19]. Therefore, the compatibility between PLA and EVA can be
achieved by tuning the VA content of the EVA copolymer without the need for additional compatibilization.
