To provide a laminate tube raw fabric for manufacturing a laminate tube having both "short-term shape retention performance" with which after the laminate tube is crushed and deformed to squeeze out a content, the laminate tube is kept in the crushed state until it is resealed and "restoration performance with lapse of time" with which the shape of the laminate tube is restored in a significant period of time after it is resealed.SOLUTION: Provided is a laminate tube raw fabric 10 with a first sealant layer 1, a first aluminum layer 2, an intermediate layer 3, a second aluminum layer 4 and a second sealant layer 5 in this order. The thickness of the intermediate layer 3 is more than 60 μm, and the total thickness of the laminate tube raw fabric 10 is 250 μm or more.SELECTED DRAWING: Figure 1 【課題】内容物を絞り出すために押し潰されて変形した後、再密閉されるまでの間は、押し潰された変形状態が維持される「短期形状保持性」と、再密閉された後には、有意の時間でチューブの形状が復元される「経時復元性」とを併有するラミネートチューブを製造するためのラミネートチューブ原反を提供すること。【解決手段】第１のシーラント層１、第１のアルミニウム層２、中間層３、第２のアルミニウム層４、及び第２のシーラント層５をこの順に有するラミネートチューブ原反１０であって、中間層３の厚みが６０μｍ超であり、ラミネートチューブ原反１０の総厚みが２５０μｍ以上である、ラミネートチューブ原反１０。【選択図】図１
