The shrink temperature is a key technology parameter in the heat shrink packaging production system; it will directly effect the quality of packing production. The intelligent control of the heat shrink temperature has an advantage of the heat shrink temperature control. The fuzzy control is applied in the heat shrink production system. And the four functions of the lead feedback compensation, performance measurement, control parameter modification, control rule modifications are added and the fuzzy control is adapted in the new system. The high precision of the new system is gotten. The steady-state errors of the heat shrink temperature are decreased and the contraction quality of the heat shrink film is increasing.
