The present invention relates to a mat for use on indoor and outdoor floors, and more particularly, to a polymeric sheet firmly attached to each other by heating and pressing an elastic skin and a sponge member through a hot melt mesh sheet, and On the other hand, after forming the foam molding layer, by forming a molten bottom layer by heating on the bottom of the foam molding layer or inserting a silicone elastic band as necessary,
It is possible to create a strong mutual adhesion state between the elastic skin and the sponge member and the foam molding layer, so that the stretchable skin can be prevented from falling off or lifting from the sponge member or the foam molding layer.Even if the cushioning mat is folded or rolled and stored, it is stretchable and A sponge member with excellent elasticity can prevent wrinkles from occurring in the elastic skin, which is a skin material, and the molten bottom layer prevents dust, foreign matter, and moisture from entering the interior of the foam molding layer, thereby contaminating the mat or preventing mold, etc. As it can be prevented from occurring, the service life can be significantly extended, as well as a more pleasant and clean use effect.
