Zusammenfassung:To provide a laminate capable of producing a container package having excellent heat resistance and acid resistance and having low waste cost and also having excellent moldability.SOLUTION: A laminate comprises an internal layer and a pair of external layers laminated on both the sides of the inner layer. The internal layer comprises an inorganic filler and a thermoplastic resin. Each external layer comprises a thermoplastic resin. The inorganic filler comprises calcium carbonate particles. The content ratio of the inorganic filler in the laminate is above 50 mass%. The thickness ratio of the external layers is respectively 2.0 to 20.0% to the whole thickness of the laminate.SELECTED DRAWING: Figure 1 【課題】耐熱性及び耐酸性に優れると共に廃棄コストが低い容器包装を製造でき、かつ成形性に優れる積層体を提供する。【解決手段】本発明の積層体は、内層と、前記内層の両面に積層される一対の外層とを備える。前記内層は、無機充填剤及び熱可塑性樹脂を含有する。前記外層は、熱可塑性樹脂を含有する。前記無機充填剤は、炭酸カルシウム粒子を含む。前記積層体における前記無機充填剤の含有割合は、５０質量％超である。前記外層の厚さの比率は、前記積層体の全体厚さに対して、それぞれ、２．０％以上２０．０％以下である。【選択図】図１
