A method of manufacturing a PTP sheet for pharmaceutical drug packaging from which a solid pharmaceutical drug is easily taken out and in which a pocket portion is hard to be accidentally damaged. The PTP sheet has a first sheet from which a pocket portion capable of housing a solid pharmaceutical drug protrudes to the side of an upper surface and a second sheet which is stuck to a lower surface of the first sheet and which closes an opening of the pocket portion. The pocket portion has a peripheral wall portion having a peripheral surface continuous with the upper surface and a top portion having a top surface continuous with the peripheral surface of the peripheral wall portion. A wall thickness of the peripheral wall portion is smaller than a wall thickness of the top portion.

Method of manufacturing a PTP sheet for packaging a pharmaceutical drug

A PTP sheet for pharmaceutical packaging has a first sheet in which pockets each capable of housing a solid pharmaceutical are projected to the side of a first surface which is one of a back surface and a front surface and a second sheet which is pasted to a second surface opposite to the first surface in the first sheet and covers an opening of the pocket. The second sheet has a first region having mesh-shaped grooves having a first depth in a third surface opposite to the surface to be pasted to the second surface and a second region having mesh-shaped grooves having a second depth smaller than the first depth or not having a groove.

PTP sheet for drug packaging

A medicine packaging PTP sheet capable of protecting a pocket from pressurization by external force in a combined state in which the medicine packaging PTP sheet has a first sheet in which a pocket capable of accommodating a medicine and a projecting convex portion each are projected from the upper surface and a second sheet which is attached to the lower surface of the first sheet and blocks an opening of the pocket. A first distance Lfrom the upper surface of the first sheet to the projection end of the convex portion is longer than a second distance Lfrom the upper surface of the first sheet to the projection end of the pocket.
