Disclosed are a resin composition and a molded article using the same. The resin composition may be obtained by mixing a thermoplastic vulcanizate and a polyethylene resin with a thermoplastic olefin resin, a polypropylene resin, an inorganic filler and a thermoplastic rubber, and in particular, the thermoplastic vulcanizate and the polyethylene resin may be obtained from biologically obtainable materials (biomass). Thus, the resin composition may be environmentally-friendly because it does not emit offensive odor of harmful compounds due to decreased generation of carbon dioxide and volatile organic compounds unlike petroleum-based materials. Further, superior mechanical properties such as elongation, hardness, strength, etc. that cannot be achieved only with conventional biodegradable resin may be ensured, and, at the same time, processability and moldability may be improved. 1.

The invention relates to a low application temperature amorphous poly-α-olefin adhesive used on nonwoven articles. The adhesive is particularly useful in the construction of nonwoven articles, e.g., disposable absorbent articles such as diapers, feminine hygiene articles, adult incontinence devices, underpads, bed pads, industrial pads and the like.Hot melt adhesives are applied to a substrate while in a molten state and cooled to harden the adhesive layer. Such adhesives are widely used for various commercial and industrial applications such as product assembly and packaging, and have been widely used in the nonwoven industry to make nonwoven articles. In these applications, adhesive is applied to at least one substrate for binding the substrate to a second similar or different substrate.In a hot melt adhesive, base polymer provides cohesive strength and elasticity. The use of high molecular weight polymer or high polymer content usually promotes cohesive strength and adhesion; however, it also results in significant melt viscosity increase.
