The tensile behavior of polyethylene/ethylene vinyl acetate (PE/EVA) polymer blends filled with calcium carbonate (CaCO 3 ) was studied using tensile and viscoelastic tests. The relations between tensile properties (modulus, strength, etc) of oriented and unoriented PE/EVA‐CaCO 3 , and void volume of polymer/CaCO 3 interface, PE/EVA blend ratio, and CaCO 3 content were investigated. The results indicated that the tensile strength and elongation of PE/EVA‐CaCO 3 decreased with CaCO 3 content and PE blend ratio for unoriented PE/EVA‐CaCO 3 systems. In the case of oriented samples, the relative modulus ( E d c / E d p , where E d cand E d pare the modulus of oriented composites and the modulus of oriented matrix, respectively) of PE/EVA‐CaCO 3 is larger than that of PE/CaCO 3 by increasing the EVA content relative to PE and CaCO 3 . The value of E d c / E d pcan be simply expressed as the function of void volume and CaCO 3 modulus to polymer matrix modulus.
