Provided is a layered body (40) for a PTP or blister pack in which an absorption layer (50) is layered on a substrate layer (70) via an adhesive layer (60). The absorption layer (50) has a configuration in which an outer skin layer (52), an intermediate layer (51), and an inner skin layer (53) are layered in the stated sequence, and the outer skin layer (52) is bonded to the substrate layer (70) via the adhesive layer (60). The outer skin layer (52) is composed of a polyethylene resin, the intermediate layer (51) is composed of a mixture of a polyethylene resin and an absorbent, and the inner skin layer (53) is composed of a blended resin having 25 to 50 mass% of a linear low-density polyethylene, and 75 to 50 mass% of a high-density polyethylene having a higher melting point as a material than the preheating temperature in the molding process. Preferably, the blended resin of the inner skin layer (53) has 10 to 50 mass% of a linear low-density polyethylene, and 90 to 50 mass% of a high-density polyethylene having a higher melting point as a material than the preheating temperature in the molding process.提供一種PTP或泡殼包裝用積層體(40)，隔著接著層(60)將吸收層(50)積層於基材層(70)。吸收層(50)具有外表層(52)與中間層(51)與內表層(53)以此順序積層的構成，隔著接著層(60)外表層(52)被接著於基材層(70)。外表層(52)由聚乙烯樹脂構成，中間層(51)由聚乙烯樹脂及吸收劑的混合物構成，內表層(53)由具有25~50質量%的線性低密度聚乙烯，與75~50質量%的作為材料的熔點比在成形過程的預熱溫度高的高密度聚乙烯之摻合樹脂構成。較佳為內表層(53)的摻合樹脂具有10~50質量%的線性低密度聚乙烯，與90~50質量%的作為材料的熔點比在成形過程的預熱溫度高的高密度聚乙烯。
