PROBLEM TO BE SOLVED: To provide a disposable body warmer excelling in biodegradability after use while an inner bag has sufficient physical properties (strength) when in use.SOLUTION: An exothermic composition containing potassium chloride and/or sodium chloride is stored in the inner bag containing an oxidative decomposition agent. Biodegradability after use can thereby be improved while maintaining sufficient physical properties (strength) when in use. |
