ペツト等の下地材として使用されている。 Ethylene resin foam sheets have thermal insulation, soundproofing,
Because it has excellent properties such as flexibility and cushioning properties, it is used as a base material for decorative paper, carpets, etc. on floors, walls, ceilings, etc.
しかしながらエチレン系樹脂発泡シートは温

It was developed to provide an ethylene resin foam sheet that does not stretch or shrink, and its gist is that it is a laminated sheet made by heat-sealing ethylene resin foam sheets to both sides of kraft paper, which is laminated with polyethylene on both sides. Exists on the sheet.

しい。 The ethylene resin foam sheet used in this invention is a foam sheet made of ethylene resin, and the ethylene resin includes polyethylene, a mixture of polyethylene as a main component with other polymers, and ethylene as a main component. Examples of the copolymers include ethylene-vinyl acetate copolymers, ethylene-vinyl chloride copolymers, and the like. Further, the foam sheet is preferably a crosslinked foam sheet, the cell structure is preferably a closed cell structure, and the expansion ratio is preferably 10 to 40 times.

に積層されたものとなる。 In the present invention, the polyethylene-laminated kraft paper and the ethylene resin foam sheet are laminated by heat fusion. When heat-sealing is performed, the polyethylene of the kraft paper and the ethylene resin of the foam sheet melt and become integrated, and are strongly adhered to each other, resulting in a strong laminate of the kraft paper and the foam sheet.
次に本考案の１例を図面で説明する。 Next, an example of the present invention will be explained with reference to the drawings.

れて強固に積層されている。 FIG. 1 is a sectional view showing an example of the laminated sheet of the present invention. In the figure, 1 is a crosslinked polyethylene foam sheet with a foaming ratio of 30 times and closed cells, and 2 is kraft paper with polyethylene laminated on both sides. Foam sheet 1 and kraft paper 2 are heat-sealed and laminated firmly has been done.
この積層シートは、発泡シート１が伸縮しよう

度も大きくなるのである。 In this laminated sheet, even if the foam sheet 1 tries to expand or contract, the expansion and contraction is suppressed because the kraft paper with low elasticity is laminated. In addition to having these excellent properties, it also has greater overall strength.
本考案の積層シートは上述の如く構成されてい

ある。 Since the laminated sheet of the present invention is constructed as described above, it does not expand or contract even when temperature and humidity change, and therefore does not blister or wrinkle, and does not impair its appearance. For example, it is suitably used as a base material for decorative paper, carpets, etc.
