NOVELTY - Preparing flexible packaging film involves forming graphene-silane coating solution, coating surface of aluminum alloy foil with prepared graphene-silane coating solution, and after drying, surface of aluminum alloy foil is coating with graphene-silane coating, compounding aluminum alloy foil with resin film, laminating side of aluminum alloy foil coating with graphene-silane coating with resin film, coating other surface of aluminum alloy foil with prepared graphene-silane coating solution, and after drying, surface of the aluminum alloy foil is covering with graphene-silane coating. The aluminum alloy foil is composited with resin film. The side of aluminum alloy foil is coated with graphene-silane coating which is combined with resin film. USE - Method for preparing flexible packaging film. ADVANTAGE - The method enables to prepare flexible packaging film that saves technical process and production time, and improves production efficiency.
