A plurality of connecting pieces arranged at intervals are fixedly connected between the outer bag body and the inner bag body. A lining is fixedly connected to the inner surface of the inner bag body, and the lining is composed of a foam layer and an antibacterial layer connected to the inner surface of the foam layer.

[0007] As a preferred implementation manner, one end of the sealing cover piece is connected with a folding part, an adhesive tape is fixedly connected to the inner surface of the folding part, and a release film covers the surface of the adhesive tape.

[0008] As a preferred embodiment, a silica gel sealing strip adapted to the upper opening of the inner bag body is fixedly connected to the inner surface of the sealing cover sheet.

[0009] As a preferred embodiment, a plurality of relief grooves adapted to the connecting pieces are formed around the thermal insulation cotton.

[0010] As a preferred embodiment, a transparent label slot is provided on the outer surface of the outer bag body.

[0011] As a preferred embodiment, the antibacterial layer is aluminum foil paper, and a nano-silver ion coating is applied to the surface of the antibacterial layer.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] For this food PE packaging bag, through the settings of the loop groove, thermal insulation cotton and pull belt, if the packaged food needs thermal insulation, the thermal insulation cotton is inserted into the loop groove; if the packaged food does not need thermal insulation, the pull belt can be used to pull out the thermal insulation cotton from the loop groove, which can be reused, reduce waste of resources and improve the applicability of the packaging bag.

[0014] For this food PE packaging bag, through the setting of the inner lining, the foam layer can improve the anti-collision, anti-compression and buffering capabilities of the packaging bag, and the antibacterial layer can improve the antibacterial and mildew-proof effects of the packaging bag, making the food in the packaging bag not easy to deteriorate.
