PROBLEM TO BE SOLVED: To provide a laminate that uses high proportion of polylactic acid and that can be used as a bottom material for a PTP package and blister package.SOLUTION: The laminate 10 comprises surface layers 12, 13 on both sides and a polylactic acid layer 11 as an interlayer. The polylactic acid layer 11 and the surface layers 12, 13 are laminated via adhesive layers 14, 15, respectively. The thickness of the polylactic acid layer 11 is 20% or more of the total thickness of the laminate 10. The surface layers 12, 13 are preferably a layer comprising any one selected from polypropylene-based resin, polyethylene-based resin, polyvinyl chloride, vinylidene chloride resin and fluorine-based resin. |
