Abstract: Provided is a laminate excellent in non-adsorbing property and excellent in adhesion strength between a base material layer and a sealant layer, despite the fact that an adhesive layer between the layers is thin. A laminate (1) according to the present invention includes a base material layer (11), an adhesive layer (14) having a thickness in a range of 0.1 µm to 1.0 µm, and a non-oriented sealant layer (15) having a thickness in a range of 10 µm to 40 µm and made of a cyclic polyolefin resin, wherein one main surface of the sealant layer (15) constitutes an outermost surface of the laminate (1), the other main surface of the sealant layer (15) is bonded to the base material layer (11) via the adhesive layer (14), and an adhesion strength between the base material layer (11) and the sealant layer (15) is 0.8 N/15 mm or more.

Abstract: Provided is a laminate which is less likely to cause adsorption and delamination. A laminate (1) according to the present invention includes a base material layer (11), and a sealant layer (14) provided on the base material layer (11), the sealant layer (14) comprising a first layer (14a) having one main surface constituting one outermost surface of the laminate (1) and the other main surface facing the base material layer (11), and containing only a cyclic olefin resin as a resin, and a second layer (14b) interposed between the base material layer (11) and the first layer (14a) and containing an ethylene-methacrylic acid copolymer, wherein a ratio of a thickness of the first layer (14a) to a thickness of the second layer (14b) is in a range of 1:3 to 6:1.
