Abstract

The invention provides an environment-friendly cold storage bag for foods. The packing bag provided by the invention differs from a packing bag in the prior art, and the packing bag in the prior art has a simple packaging function only, and has no cooling and freezing functions. However, the packing bag provided by the invention has such functions, and a cavity is formed in the traditional packingbag; heat-absorbing materials are arranged in the cavity, and surrounding heat can be absorbed by the heat-absorbing materials continuously, so that the cooling effect is achieved; thus, the internaltemperature of the packing bag is reduced, and the foods are placed in a cold air environment, and prevented from going bad and decaying at high temperature within a short time; and the edible effectis not affected.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine, and in particular relates to an environment-friendly refrigerator bag used for food. Background technique [0002] With the progress of the times, people's lifestyles have also undergone great changes, and there are greater requirements for the quality of life. In addition to work, people are more pursuing leisure and relaxation in leisure time. Therefore, picnics have become people's leisure time. more common way. [0003] It is inevitable to bring food during a picnic, but if the weather is hotter in summer, the food will easily deteriorate under high temperature conditions, affecting the quality of the food, or even inedible, resulting in waste. [0004] Therefore, in order to solve the above-mentioned problems, the present invention develops an environmentally friendly refrigerator bag for food. Contents of the invention [0005] Aiming at the defects in the prior art...
