Preferably, the bag body comprises a plastic layer, a foam layer is arranged on the inner side of the plastic layer, a heat insulation layer is arranged on the inner side of the foam layer, and an antifouling layer is arranged on the inner side of the heat insulation layer.

Preferably, two handle grooves are formed in the inner side of the bag body, and a foam protection ring is fixedly connected to the inner side of the bag body.

Preferably, the bottom of the inner wall of the bag body is provided with a hard bottom plate.

Preferably, the heat-insulating layer is made of a tinfoil paper material, and the antifouling layer is made of a plastic film material.

Preferably, the magic male tape and the magic female tape are connected with the bag body in a sewing mode.

Compared with the prior art, the utility model provides a pair of novel thermal-insulation plastic bag has following beneficial effect:

the utility model provides a novel heat preservation plastic bag, through magic positive paste with the laminating back of magic negative paste, can seal the bag body, avoid the heat to run off from the top of the bag body to can improve the heat preservation effect of the bag body, and simple convenient during the operation, through the use in handle groove, can reduce the material of the bag body, the problem of reining in the hand when the foam guard ring can avoid carrying and taking.
