Due to the discoloration, it can be easily recognized that the temperature of the box is rising, and the user can be alerted.
Some temperature indicating paints and temperature indicating inks are irreversible that do not return to their original colors even when cooled. In the case of a box containing medicine, etc., discolored parts with these irreversible temperature indicating paints and temperature inks. It is good to form.

Furthermore, an ultraviolet discoloring agent that absorbs ultraviolet rays and changes color when exposed to sunlight may be kneaded or applied to the entire plastic sheet of the intermediate layer having a three-layer structure.
In such a case, when the light hits the box and the temperature rises, the box is colored, and a light shielding effect is obtained, so that the temperature rise of food stored in the box can be prevented. It becomes.
In the case of a plastic two-layer structure or a three-layer structure, it is desirable that the opening portion of the end face be closed.
