摘要： A sheet made from a foamed polystyrene resin which is heat-shrinkable in one axial direction and has a heat-insulatingness is prepared. A printing process is applied to this sheet to produce a label. A container made from a thermo-plastic resin is covered with said cylindrical label and is put in a furnace in order to heat-shrink the label to be fitted on the container.The container with the label manufactured in accordance with the present invention has a superior heat-insulatingness, and thus can maintain the temperature of water contained therein for a longer time. Also, when it is used in a electronic-range, a temperature of an outer wall surface of the container can be prevented from increasing, and thus the container can be held by a bare hand even immediately after cooking.
