▎ 摘  要

NOVELTY - Pharmaceutical packaging sheet comprises a base layer, a first adhesive layer formed on the base layer, an aluminum layer formed on the first adhesive layer, a second adhesive layer formed on the aluminum layer, and a resin layer 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 pharmaceutical packaging material. ADVANTAGE - The sheet has excellent gas permeability, mechanical strength and pinhole resistance, has less deterioration in strength at low temperature, and is economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing the pharmaceutical packaging sheet involving 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.
