Embodiment approach 1
[0048] Below, refer to figure 1 Embodiment 1 of the present invention will be described.
[0049] The wallpaper 10 of the present invention has the following laminated structure: the thermoplastic resin film layer 20 is laminated and bonded on one side of the bulky non-woven fabric layer 3 by a hot-melt method; A polyolefin laminate base paper layer 4 having an extrusion laminated layer of a fusion-bonding polyolefin resin on one side, the extrusion laminated layer being on the inner side (nonwoven fabric layer side), is laminated and bonded by a hot melt method. The other surface of the non-woven fabric layer 3 is connected, and then heat embossing is performed from the side of the thermoplastic resin film layer.
[0050] The non-woven fabric 3 used in the wallpaper 10 of the present invention is not particularly limited, as long as it has softness, flexibility, non-hygroscopicity and bulkiness, it can adopt spunbonded (spunbonded) fabric, jet spray net (spunlace) : Spunlac...
