CN116943A
An inner bag packaging material that uses iron powder as a main raw material and generates an oxidative exothermic reaction by contact with oxygen in the air and can generate a constant and stable heat (including warming hands, warming the feet, warming the body). Methods using microporous breathable membranes. It is characterized by the fact that the warm bag can react with oxygen uniformly when used, and generate stable heat, and at the same time, avoid leakage of the reactants after drying.
