Abstract The present invention provides a multilayer body which comprises at least a base material layer and a sealant layer, wherein: the sealant layer is positioned on at least one outermost surface of the multilayer body; the sealant layer is a resin layer that contains a polyhydroxyalkanoate resin component; the highest melting peak temperature in the differential scanning calorimetric analysis of the polyhydroxyalkanoate resin component is 130°C or more; and the total crystal melting enthalpy as calculated from all melting peaks is within the range of 20 J/g to 65 J/g. La présente invention concerne un corps multicouche qui comprend au moins une couche de matériau de base et une couche de produit d'étanchéité, la couche de produit d'étanchéité étant positionnée sur au moins une surface la plus à l'extérieur du corps multicouche; la couche de produit d'étanchéité étant une couche de résine qui contient un composant de résine de polyhydroxyalcanoate; la température de pointe de fusion la plus élevée dans l'analyse calorimétrique différentielle à balayage du composant de résine de polyhydroxyalcanoate est au moins 130 °C; et l'enthalpie de fusion cristalline totale telle que calculée à partir de tous les pics de fusion se situe dans la plage de 20 J/g à 65 J/g 少なくとも、基材層とシーラント層とを含む積層体であって、前記シーラント層は、前記積層体の少なくとも片側の最表面に位置し、前記シーラント層は、ポリヒドロキシアルカノエート系樹脂成分を含む樹脂層であり、該ポリヒドロキシアルカノエート系樹脂成分の示差走査熱量分析における最も高い融解ピーク温度が130℃以上であり、かつ、全ての融解ピークから算出される総結晶融解エンタルピーが20J/g~65J/gの範囲である、積層体。
