PURPOSE: An aluminum laminate sheet is provided to improve printing contrast and brilliance by using a corona-treated PET, NY, OPP or CPP film as a printing film which forms a printing layer. CONSTITUTION: An aluminum laminate sheet comprises an aluminum thin film layer(10), a first adhesive layer(21), a first polyethylene film layer(30), a second polyethylene film layer(40), a second adhesive layer(22), a printing film layer(50), a third adhesive layer(23), and a third polyethylene film layer(60). The first adhesive layer is formed on one side of the aluminum thin film layer. The first polyethylene film layer is formed on the surface of the first adhesive layer and forms an inner side of a tube. A second polyethylene film layer forms the other side of the aluminum thin film layer. The second adhesive layer is formed on the surface of the second polyethylene film layer. The printing film layer is formed on the surface of the second adhesive layer. The third adhesive layer is formed on the surface of the printing film layer. The third polyethylene film layer is formed on the surface of the third adhesive layer. |
