Preparation of Low Density Polyethylene – Ethylene Vinyl Acetate Copolymer (LDPE-EVA) Blend Films for Packaging Applications

Polyolefin films have a remarkable position in packaging industry, due to their low cost, easy production and required properties. In particular, Low density polyethylene (LDPE)has the highest usage volume in packaging applications [1]. However, its scratch and impact resistance is low which canbe improved via blending with other polymers [2]. Film grade ethylene – vinyl acetate copolymer (EVA,) follows the same feature of market growth as LDPE and has theversatile applications, for example in non-scratch films [3]. EVA is commonly used in blends with polyolefins in order toimprove their mechanical and impact strength. It also increases transparency of the sample. LDPE-EVA blends suggest the plastic products with good performance, low costand appropriate process-ability [4]. In this work, preparation and properties of LDPE-EVA blend films with the aim of preparing attractive films and satisfying the required properties for packaging applications are studied
