In this paper, uniaxial tensile tests of ETFE films with three kinds of thicknesses(100, 200, 250μm) and two kinds of directions(machine direction & transverse direction) are performed and the tensile strength, the tensile strain at break and the Young’s modulus of ETFE films are compared for two kinds of specimen types(2 & 5). It could be figured out that there are no significant difference between tensile strengths of two specimen types but the tensile strain at break and the Young’s modulus of ETFE films are affected by the specimen types. And it is concluded that the uniaxial tensile test of specimen type 2 are more reliable than that of specimen type 5.
