NOVELTY - The utility model claims a flexible packaging structure with high barrier property, comprising: a polymer layer and a heat-sealing layer; between the polymer layer and the heat-sealing layer is provided with a graphene layer; between the polymer layer and the graphene layer is provided with a mixed slurry layer; between the heat-sealing layer and the graphene layer is provided with a mixed slurry layer; Thus, on the one hand, using non-permeable graphene layer as a core barrier, a polymer layer as an external protective encapsulation, using the synergistic effect between the barrier and the protective encapsulation can obviously reduce the permeability of oxygen and moisture; On the other hand, using the mixed slurry layer as the buffer layer between the polymer layer and the graphene layer greatly increases the adhesion of graphene on the polymer film, so as to create very good barrier ability.
