In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a PET tectorial membrane carton, includes the carton body, the carton body includes cardboard A, cardboard B, insulating layer and dampproof course, the gluing of this internal surface of carton has tectorial membrane A, the gluing of carton body surface has tectorial membrane B, this internal bottom of carton and top are equipped with braced frame A and braced frame B respectively, the periphery evenly is provided with branch between braced frame A and the braced frame B.

Further, the paper board A and the paper board B are respectively adhered to the top surface and the bottom surface of the heat insulation layer and the moisture-proof layer, and the moisture-proof layer is adhered to one side surface of the heat insulation layer.

Further, the heat insulation layer is ceramic fiber cotton, and the moisture-proof layer is polystyrene foam material.

Further, the supporting frame A, the supporting frame B and the supporting rods are all made of polyethylene materials; and supporting the space between the supporting frame A and the supporting frame B through the supporting rods.

Further, the coating film A is a PE film, and the coating film B is a PET film; the coating film B is a PET film, so that the PET film has a high temperature resistant effect and can resist the high temperature in summer.

Compared with the prior art, the utility model has the following beneficial effects:

1. through setting up insulating layer and tectorial membrane B, utilize the insulating layer to be ceramic fibre cotton in order to reach the high temperature resistance of this carton body to utilize tectorial membrane B of carton body surface to have high temperature resistant effect for the PET membrane, can bear the high temperature in summer, further make carton body content not receive the high temperature influence.

2. Through setting up braced frame A, braced frame B and branch, utilize braced frame A, braced frame B and branch cooperation to support in the carton body is inside, plays the supporting role to the box to reach certain anti-deformation effect.
