Melt bags of the invention are molten uniformly at temperatures lower than melting operation temperatures in the product manufacturing and do not remain unmolten in the final products. The melt bags have high storage stability and excellent mechanical properties. Resin compositions of the invention are suited to give such melt bags. A resin composition of the invention includes a propylene/C2-20 &#x3b1;-olefin (except propylene) copolymer (A) having (1) a melting point (Tm) of not more than 90&#xb0; C. as measured by differential scanning calorimetry (DSC) or not showing a melting point peak in DSC, and an ethylene/C3-20 &#x3b1;-olefin copolymer (B) having (1) a melting point (Tm) of not more than 90&#xb0; C. as measured by differential scanning calorimetry (DSC) or not showing a melting point peak in DSC, the weight ratio of these copolymers (A)/(B) being in the range of 99/1 to 1/99.

Resin composition and melt bag

A laminated structure composed of a substrate web and a thermoplastic resin web extrusion-coated thereon, which is substantially free from an offensive odor, is produced by extrusion-coating the thermoplastic resin web in the molten state through a T-die on the substrate while applying an oxidizing gas to one surface of the as-extruded molten web of the thermoplastic resin and an inert gas to its other surface in a specified space.
