[0009] Furthermore, the cast polypropylene layer includes polypropylene monomers and linear polyethylene monomers.

[0010] Furthermore, a first adhesive layer is provided between the aluminum foil layer and the heat sealing layer.

[0011] Furthermore, a second adhesive layer is provided between the aluminum foil layer and the protective layer.

[0012] Furthermore, the protective layer is a polyester layer.

[0013] Furthermore, the thickness of the polyester layer is 0.01-0.05 mm;

[0014] The thickness of the aluminum foil layer is 0.03-0.07mm;
