The two kinds of strain-time factorized type (type I and type II), and the strain-time reduced type (type III) of superposition principle are examined, for two kinds of polyethylene film. The values of tensile stress calculated from the theory of type III, compared to the other types, agree fairly well with the experimental data. When the additional strain is positive in the two-step relaxation, the type III has better applicability than the other types at small strain. On the other hand, when the additional strain is negative, all the predicted curves are apparently above the observed curves. For high density polymers, in contrast to low density polymers, the theory can be applied only in the limited range of small strain.
