The heat-preservation environment-friendly food packaging box comprises an inner container and an outer box, wherein the inner container is arranged in the outer box, the upper edge of the inner container is completely attached to the upper edge of the outer box, and a heating heat-preservation material is arranged between the inner container and the outer box. The prepared heating heat-preservation material has high water absorption performance and heat preservation performance and has the advantages of being free of toxin and pollution, light and the like, the heat-preservation box can be kept at a high temperature for a long time, meanwhile, the prepared multifunctional material can be repeatedly used, raw materials are saved, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of food packaging, in particular to a thermal insulation and environment-friendly food packaging box and a production method thereof. Background technique [0002] At present, the plastic packaging boxes commonly used in restaurants cannot keep food at a suitable temperature for a long time. Whether you can eat a hot meal has become a big problem. The stomach is very picky about food, raw, hard, cold, sour, spicy and other irritating food will affect the work of the stomach. The normal work of many digestive enzymes requires a suitable temperature. Long-term consumption of cold meals will affect the secretion of gastric acid and the function of digestive enzymes. If things go on like this, you may suffer from stomach diseases such as gastric ulcer and superficial gastritis. [0003] Chinese patent (application number: 202010511901.2) discloses an environmentally friendly biodegradable food packaging box, w...
