Further, the adhesive film 7 can be made of an ionomer resin. When the adhesive film 7 is made of an ionomer resin, when the ionomer resin is heated, ionic cross-linking between long chain molecules is weakened and the heat flowability is exhibited. When the back sheet material 5 side made of a non-woven fabric is impregnated with a metal powder such as aluminum, the ionomer resin flowing down due to heat permeates into the back sheet material 5 to replace the metal ions inside and is cooled. After that, the network structure of the molecule is fixed by ionic bond, and the extremely strong seal portion C can be obtained. Also, since the ionomer resin can be sealed at a low temperature, the heat sealing can be completed at a low temperature.

It is printed using a method such as dry laminating or extrusion laminating, and a metallic oil-based ink can be used as the temperature-indicating paint 8. Since it is hermetically sealed, outflow to the outside is completely prevented. It is in the state of being The temperature-indicating paints 8, 8 and 8 cause a color change due to the temperature change in the bag space K, and the freezing temperature and the melting temperature of the water-absorbent polymer 9 in the bag space K can be easily visually observed from the outside. It is a thing. In addition, this temperature indicating paint 8,8,
8 can be used to draw advertising characters or figures on the front sheet material 6, and the figures and the like change color due to changes in temperature, so that the advertising effect of the cold insulating sheet 4 can be further improved.
