METHOD FOR COVERING PET BOTTLE, HAVING COOLING MEANS, WITH HEAT-SHRINKABLE FILM AND COOLING MEANS THEREFOR

摘要

The present invention relates to a method for covering a PET bottle, having a cooling means, with a heat-shrinkable film, and inserts a holder cap, which is connected to a cooling and air-conditioning system so as to supply cooling air to the inside of the PET bottle during a heat-shrinkage and covering process of a label, into the mouth of the PET bottle so as to inject the cooling air into the PET bottle, thereby preventing the PET bottle itself from being thermally deformed during the shrinkage and covering process of a label.
