The article contains research results of deformation characteristics of belkozin membrane obtained owing to the application of hysteresis loops technique. A number of important parameters for automated production have been established, e.g. plasticity properties, film strengthening phenomenon at cyclic load, reverse deformation dynamics, etc. It was found that belkozin features nonpersistent offset strain dependant on cyclic load. Offset strain produces its highest value during the first loading cycle and is declining with every new cycle. The results can be used in setting optimal parameters of automated sausage production.
