<p>PURPOSE:To improve interlayer adhesive strength of a laminated body, by using a sheet-like material prepared by laminating polyolefine in advance and by using a polyolefine film to be laminated after making it a molten web. CONSTITUTION:A molten polyolefine web whose temp. is in the range of m.p. or softening point of a film to be laminated and 100 deg.C higher than the m.p. or the softening point is piled up on the polyolefine side of a sheet-like material on which polyolefine is being laminated in advance and thereafter pressed and laminated. As above described, as polyolefine is being extrude and laminated on another sheet-like material in advance, the interlayer adhesive strength is high and no peeling occurs later between the laminated layers. As the molten polyolefine web to be laminated is kept at a relatively lower temp., loss of chemicals by evaporation and deterioration by heat of polyolefine are relatively small.</p> |
