Description

technical field [0001] The present application belongs to the technical field of packaging containers and relates to a self-heating packaging box for packaging food intended to be cooked or heated in the package. Specifically relates to a self-heating degradable packaging box and a preparation method thereof. Background technique [0002] In recent years, self-heating convenience food has been widely welcomed by consumers. Self-heating convenience food packs the ingredients that need to be heated and cooked into the packaging box. A separate chamber is provided around or at the bottom of the packaging box, and the self-heating medium is contained in the chamber. The self-heating medium is usually aluminum powder or magnesium powder or calcium oxide. The above-mentioned substances release heat when they meet water, so as to heat the food. [0003] Exemplarily, the Chinese invention patent document with the publication number CN109969617B discloses a self-heating bottle, w...
