PROBLEM TO BE SOLVED: To provide an inexpensive multilayer sheet for packaging with excellent moisture-proofness, its manufacturing method and a press-through-pack container to solve the problem that the cost increases as a PVDC layer is formed in a thick layer or a PCTFE film is used. SOLUTION: A moisture barrier layer with excellent moisture barrier properties which contains an ethylene-vinyl alcohol based polymer and an inorganic layered compound is laminated, thereby providing an inexpensive multilayer sheet for packaging and a PTP container with good moistureproof characteristics even with a thin moisture barrier layer.
