NOVELTY - A PET bottle with high barrier property, comprising a bottle body and a bottle cover, the bottle body to form a three-layer composite structure, which in turn comprises a PET film, graphene film, PET film. thickness of the PET film is 10-40um, the graphene film is 1-20um mm thick. PET bottle with high barrier property of this utility model, it not only can prevent oxygen and carbon dioxide gas, at the same time, can block light, storing the beer better barrier, such as high demand of food.
