PROBLEM TO BE SOLVED: To obtain a nonwoven polypropylene fabric for a food packaging, which has improved stickiness, smell, heat sealability and elutability and excel lent flavor properties. SOLUTION: This nonwoven polypropylene fabric for the food packaging comprises a propylene/α-olefin random copolymer fiber as at least one component, which is polymerized by a metallocene catalyst, has 10-100 g/10 minutes MFR, 2.0-4.0 Q value, 110-140 deg.C Tm, <=10 deg.C T80 -T20 , <=3 wt.% soluble contents at 0 deg.C at TREF measurement, 1-18 mol % α-olefin contents and <=60 wt.ppm 12C-30C oligomer component content as at least one component. The nonwoven fabric has >=5,000 g/5 cm width tensile strength at least in one direction of the nonwoven fabric. |
