PROBLEM TO BE SOLVED: To provide a multilayer sheet for PTP (press-through package), which is excellent in moisture-proofing property and shock resistance.SOLUTION: The multilayer sheet for PTP comprises a layer (i) comprising a polyvinyl chloride resin (A) and a layer (ii) comprising polyvinylidene chloride resin (B), successively layered in the order of layer (i)/layer (ii)/layer (i). The layer (ii) comprises a layer (ii)-1 comprising a polyvinylidene chloride resin showing an absorbance ratio of 1.05 to 1.40 of absorbances at 1046 cmand 1070 cm, and a layer (ii)-2 comprising a polyvinylidene chloride resin showing an absorbance ratio of 0.80 to 1.05 of absorbances at 1046 cmand 1070 cm, with each one or more layers alternately layered. |
