の作用，効果は極めて顕著である。That is, since the printing layer is formed on the biaxially stretched synthetic resin film having excellent surface smoothness,
The printing is good, and it has features such that a complicated pattern can be revealed. In particular, a printed layer in a conventional extruded tube laminate is revealed by printing on the surface of the intermediate layer of the laminated sheet of the intermediate layer and the innermost layer, and further forming an outermost layer on the surface of the intermediate layer. Or, the above-mentioned effect obtained by the printing layer in the biaxially stretched synthetic resin film in which the printing layer is formed in advance, as compared with the one which is revealed by applying the printing to the surface of the laminated material, The effect is extremely remarkable.
更にまた、本考案の紙無し押出しチューブ用積層材は、
外層，中間層，内層をそれぞれ構成する合成樹脂と、場
合によって使用される接着剤とで構成されるものである
から、構成が単純であるため、安価に製造し得る。Furthermore, the laminated material for a paperless extruded tube of the present invention is
Since it is composed of the synthetic resin constituting each of the outer layer, the intermediate layer, and the inner layer and the adhesive agent used in some cases, the structure is simple and therefore the manufacturing cost can be reduced.
