| description | To provide a laminate which enables packaging of an article used in a clean environment, suppresses generation of floating between layers, and is suitable as a packaging material.SOLUTION: A laminate includes at least a first resin layer and a second resin layer, wherein the first resin layer is provided so as to be peeled from the second resin layer, peeling strength between the first resin layer and the second resin layer, which is measured under the conditions of peeling angle of 180 degrees and test speed of 50 mm/min, is 1.0 N/15 mm width or less, the second resin layer is a sealant layer having at least a polyethylene layer having density of 0.909 g/cm3 or less, and the polyethylene layer in the second resin layer is brought into contact with the first resin layer.SELECTED DRAWING: Figure 1
【課題】クリーン環境内で使用される物品を包装でき、かつ層間での浮きの発生が抑制された、包装材料として好適な積層体を提供する。【解決手段】第１の樹脂層と、第２の樹脂層と、を少なくとも備える積層体であって、第１の樹脂層は、第２の樹脂層から剥離できるように設けられており、剥離角度：１８０度、試験速度：５０ｍｍ／ｍｉｎの条件にて測定される、第１の樹脂層と第２の樹脂層との剥離強度は、１．０Ｎ／１５ｍｍ幅以下であり、第２の樹脂層は、密度が０．９０９ｇ／ｃｍ3以下のポリエチレン層を少なくとも備えるシーラント層であり、第２の樹脂層におけるポリエチレン層が、第１の樹脂層と接している、積層体。【選択図】図１ |
