RETICULATED WEB STRUCTURES Abstract of the Disclosure It has been found that reticulated web structures having a uniform thickness, soft hand and high strength-to-weight ratio comprising a first set of oriented substantially parallel flat filaments running in the machine direction intersecting a second set of oriented substantially parallel flat filaments running in the cross-machine direction, where the said filaments all have a rectangular cross-section, with the width of the filaments being at least 1.5 times their thickness, the filament intersections be- ing biaxially oriented and the first set of filaments running in the machine direction being perpendicular to the second set of filaments running in the cross-machine direction, can be prepared by drawing from about 3 to 6 times in both the machine and cross- machine directions a thermoplastic polymer film having a thickness of from about 3 to 25 mils and a pattern of round discontinuous openings aligned uniformly longitudinally and transversely in a square pattern while heating said film at an elevated temperature appropriate to obtain orientation of the filaments along their long axis and in both directions at their intersections, provided said round discontinuous openings in said film are situated such that the distance between the circumference of any opening and the circumference of any neighboring opening at the narrowest point is at least 1.5 times the thickness of the film and the ratio of the distance between the circumference of any opening and the circum- ference of any neighboring opening at the narrowest point to the diameter of the opening is from about 1 to 4 to about 1.5 to 1.
