Carton with heat preservation and cold storage functions

Abstract

The invention discloses a carton with heat preservation and cold storage functions. The carton comprises a carton body. A plurality of folded edges are arranged on the carton body, the carton body isdivided into a first bottom plate, a second bottom plate, a third bottom plate, a fourth bottom plate and an adhesion plate by the folded edges, the carton body comprises a waterproof carton, the waterproof carton comprises a first carton layer and a second carton layer, a heat preservation plate is arranged between the first carton layer and the second carton layer, corrugated plates are arrangedin the first carton layer and the second carton layer, gaps in the corrugated plates, the first carton layer and the second carton layer are filled with foam, tin foil paper is arranged on the top ofthe first carton layer, and a waterproof film is arranged at the bottom of the second carton layer. The carton has the advantages that the carton is provided with multilayer heat preservation structures, accordingly, loss of heat in the carton can be effectively reduced, and the problem of insufficient support force of existing cartons due to the fact that the existing cartons are damped by waterdrop generated outside the existing cartons can be solved by the aid of the waterproof film outside the carton.

Description

technical field [0001] The invention belongs to the field of packaging boxes, in particular to a carton with heat preservation and refrigeration functions. Background technique [0002] With the continuous improvement of living standards, people's dietary life has transitioned from the single type of food and clothing in the past to the current type of diversified nutrition. At present, under the advocacy of new nutrition concepts by experts, frozen food is generally favored, and the consumption is increasing. Due to regional and seasonal differences in frozen food, its circulation will also increase. Most of the existing carton packaging has poor insulation effect. If the weather is hot or the transportation distance is long Frozen food is easy to melt and deteriorate, causing food safety problems, and when transporting frozen food, the outside of the box is hot and the inside of the box is cold, and water droplets are easy to form on the outside of the box. After the box...
