▎ 摘　　要

NOVELTY - Conductive heating food packaging paper comprises a packaging base paper, a conductive heating layer and a polylactic acid (PLA) film layer laminated in order from bottom to top. The conductive heating layer is made of modified graphene/carbon nanotube/nanocellulose conductive heating coating, and thickness of conductive heating layer is 5-50 mu m. USE - Conductive heating food packaging paper. ADVANTAGE - The conductive heating food packaging paper is energized by 24v power supply to achieve rapid heat preservation and heating of food, ensures food safety, improves edible efficiency, has comparative advantage in activities such as mountain climbing, camping and army camp, large practical value, and avoids potential hazard such as fire caused by heating of fire. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a conductive heating food packaging paper, which involves coating modified graphene/carbon nanotube/nanocellulose conductive coating on packaging base paper, drying, applying PLA coating, drying, and cutting it to obtain final product.
