Problems solved by technology

[0003] However, the self-heating food lunch box packaging technology started late, and there are still many deficiencies in the actual use process: for example, the packaging itself is not easy to degrade, the quality is large, it is not easy to carry, the dosage of the heat source is large, and the heating rate is low. The packaging structure is unreasonable, the food is not completely isolated from the heat source, etc. These problems are likely to lead to the emergence of potential safety hazards
