PROBLEM TO BE SOLVED: To provide a blister packing body capable of forming a takeout port, and capable of restraining a curl of a flange part thermally adhering to a lid material and the opened lid material, by opening the lid material while separating a thermal adhesion part from a separation starting part, without forming a cut line in the lid material.SOLUTION: A quadrangular blister packing body is composed of a lid material composed of a laminate body and a container material for forming a content storage part, and provides a separable thermal adhesion part on the peripheral edge, and the thermal adhesion part is formed in one of a pair of edge parts and the other of the pair of edge parts orthogonal to the edge parts, and a first separation starting part in which mutual thermal adhesive resin layers of the lid material and the container material do not adhere to each other, is formed in a corner part crossing the thermal adhesion part, and the lid material is constituted so that a uniaxial drawing film is laminated to the thermal adhesive resin layer, and the drawing direction of the uniaxial drawing film coincides with the mutually opposed direction of the one of the pair of edge parts or the mutually opposed direction of the other of the pair of edge parts.SELECTED DRAWING: Figure 1 |
