Abstract: Provided is a laminate including a base material layer and a sealant layer. The sealant layer includes a first layer containing a cyclic olefin resin and a second layer interposed between the base material layer and the first layer and containing a low density polyethylene resin. A ratio of a thickness of the first layer to a thickness of the second layer is in a range of 1:2 to 5:1. The low density polyethylene resin has a melt flow rate (MFR) at 190° C. and a load of 21.168N of 3.6 g/10 min to 13.0 g/10 min. The low density polyethylene resin has a density in a range of 0.915 g/cm3 to 0.925 g/cm3. Each of the first and second layers has a thickness of 5 ?m or more, and the second layer has a thickness of 25 ?m or less.

Abstract: Provided is a laminate that includes a base material layer, and a sealant layer provided on the base material layer. The sealant layer includes a first layer having one main surface constituting one outermost surface of the laminate and the other main surface facing the base material layer, and containing only a cyclic olefin resin as a resin, and a second layer interposed between the base material layer and the first layer and containing an ethylene-methacrylic acid copolymer, wherein a ratio of a thickness of the first layer to a thickness of the second layer is in a range of 1:3 to 6:1.
