Heat insulation shopping bag

Abstract

The invention discloses a heat insulation shopping bag. The heat insulation shopping bag comprises a double-layer structure which respectively comprises an outer bag positioned on an outer layer and an inner bag positioned in an inner layer. A plastic foam heat insulation layer and a freezing medium layer are sequentially arranged between the inner bag and the outer bag. Accordingly, due to the fact that the inlayer structure serves as a heat insulation shopping bag main body, the plastic foam heat insulation layer adheres to the outer bag, and the freezing medium layer adheres to the inner bag. Accordingly, on one hand, the plastic foam heat insulation layer has heat insulation effects and can well keep the low-temperature environment of the heat insulation shopping bag through the freezing medium layer; on the other hand, and the freezing medium layer can directly provide the low-temperature preservation environment for frozen fresh-keeping foods in the inner bag. The heat insulation shopping bag greatly prolongs unfreezing time of the frozen foods, and freezing and preservation of commodities are effectively guaranteed.

Description

technical field [0001] The invention relates to a shopping bag, in particular to a thermal insulation shopping bag. Background technique [0002] In the prior art, commonly used shopping bags generally have a single-layer structure. Therefore, when buying frozen food, if the shopping place is far away from the buyer's residence, the frozen food will be thawed. And we know that frozen food is very easy to deteriorate after thawing, and after freezing again, the product cannot be preserved according to the shelf life expected by the merchant, thus affecting people's health. Contents of the invention [0003] The present invention aims at the deficiencies of the prior art, and provides an insulated shopping bag, which is specially used by buyers when purchasing frozen goods. It can greatly prolong the thawing time of frozen food and effectively ensure the frozen freshness of the product. [0004] For realizing above technical purpose, the present invention will take followi...
