NOVELTY - The utility model claims a multi-purpose graphene electric heating film, belonging to the technical field of packaging electric heating film, to solve the problem that the existing graphene electric heating film has simple structure, limited use range, and there is potential safety hazard, comprising a protective sleeve film, graphene heating film, a reflecting layer, heat preservation temperature control system, a temperature limiting device, a metal wire net and a ground wire; the heat preservation layer is located below the reflecting layer, the reflecting layer is located below the graphene heating film, the outer part of the graphene layer and the heat preservation layer is covered by a protective sleeve film, the graphene heating film is electrically connected with the temperature control system. In the utility model, through the setting of the temperature limiting device, it can improve the safety performance, the temperature limiting device is mounted on top part graphene the position of one side or bottom part, when the graphene of the packaging electrothermal film exceeds the preset temperature, the temperature limiting device can automatically cut off or send out alarm signal to the graphene
