Zusammenfassung:	To prevent entry of light from a side seam portion in a laminate tube container, particularly, to prevent entry of light through a gap between metal layer and a metal layer of a side seam part into the laminate tube container at higher accuracy.SOLUTION: A raw sheet for light-shielding laminate tube which is formed by laminating three layers or more of different materials has a layer formed of a metal material in a middle layer out of the three layers, and also has a polyolefin layer into which carbon black is blended for a layer on an inner side of a metal layer when the sheet is formed in a cylindrical body part.SELECTED DRAWING: Figure 3 【課題】本発明は、ラミネートチューブ容器におけるサイドシーム部分からの光の侵入を防止し、特にサイドシーム部の金属層と金属層の間隙からラミネートチューブ容器の内部への光の侵入をより高精度で防止する。【解決手段】本発明は、３層以上の異なった材料を積層することによって形成されている原反であって、前記３層のうち中間層に金属製材料で形成された層を有し、筒状胴部に成形された際の金属層より内側の層にカーボンブラックが配合されたポリオレフィン層を有している遮光性ラミネートチューブ用原反である。【選択図】図３
