Abstract

A melt-blown nonwoven fabric of the present invention is formed from an ethylene-(meth)acrylic acid copolymer having a melt flow rate of 50 to 1000 g/10 min measured at 2.16 kg load and at a temperature of 190 degrees in accordance with ASTM D1238, and a content of acrylic acid or methacrylic acid unit of 2 to 25 weight %. The nonwoven fabric has the sum of values of (tensile strength (g/5 cm))/(basis weight (g/m2)) in machine direction and cross direction of 30 to 100, and a residual strain after 50% extension of no more than 20%, and is excellent in gas permeability, elasticity andmoreover moderate strength. The nonwoven fabric is suitable for elasticized fabric components, packaging materials, laminates, etc.
