Abstract
A spun-blown non-woven web is disclosed which is formed from a plurality of fibers formed from a single polymer having an average fiber diameter ranging from between about 0.5 microns to about 50 microns; a basis weight of at least about 0.5 gsm; a tensile strength, measured in a machine direction, ranging from between about 20 g to about 4,200 g; a ratio of tensile strength, measured in the machine direction, to basis weight of at least about 20:1; and a ratio of percent elongation, measured in the machine direction, to fiber diameter of at least about 15.
