▎ 摘  要

NOVELTY - Packaging sheet comprises: a base layer (10); a first adhesive layer (401) formed on the base layer; an aluminum layer (20) formed on the first adhesive layer; a second adhesive layer (402) formed on the aluminum layer; and a resin layer (30) formed on the second adhesive layer, where at least one layer from the base layer, the first adhesive layer, the second adhesive layer and the resin layer includes graphene. USE - The sheet is useful in packaging material. ADVANTAGE - The sheet: increases in mechanical strength, an increase in barrier property of moisture and oxygen, and increases in chemical resistance, thus increasing flame resistance and impact resistance; and involves the graphene that increases the durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing the packaging sheet comprising forming each of a base layer, an aluminum layer and a resin layer and laminating the base layer, the aluminum layer and the resin layer in order, where a first adhesive layer is included between the base layer and the aluminum layer, and a second adhesive layer is included between the aluminum layer and the resin layer, and at least one layer from the base layer, the first adhesive layer, the second adhesive layer, and the resin layer includes graphene. DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of the packaging sheet. Base layer (10) Aluminum layer (20) Resin layer (30) First adhesive layer (401) Second adhesive layer (402)
