NOVELTY - The utility model relates to the technical field of food preservation, especially based on a phase change thermal management film of graphene comprises graphene phase-change layer and a graphene polymer preservative film phase change layer on the lower layer of the two sides, the graphene phase change layer through the heat conducting double faced adhesive tape layer and the upper polymer bonded preservative film layer of the lower two sides. After adopting the said structure, this utility model is based on phase-change thermal management film structure of graphene is simple, it is easy to produce, easy function, aspect, using scene is not limited, can be any place.
