<p>PROBLEM TO BE SOLVED: To prevent such a risk that one takes a PTP pack by mistake, by using a multi-layer film or sheet with a specified material characteristic, constituted of a polyamide layer, an adhesive layer, and a polyethylene layer as a seal layer, as the bottom material and hermetically sealing a medicine pack by a covering material chiefly composed of aluminum foil. SOLUTION: In a PTP pack(press trough pack) for solid medicine, a multi- layer film or sheet constituted of at least one or more polyamide layers and a polyethylene layer as an adhesive layer or a seal layer is used as the bottom material, which is 10g/m<2> .24hrs or lower in the moisture vapor transmissiblity, 30% or lower in the haze value, and 0.15-0.45mm in the thickness. After a chemical agent has been charged in the molded part of the bottom material, the pack is hermetically sealed by a cover material chiefly composed of aluminum foil to obtain a medicine pack. In this case, the thickness of polyethylene layer is set at 50-80% of the whole thickness and nylon 6 or a copolymer of nylon 6 and nylon 66 is preferably used as a polyamide layer.</p> |
