Abstract
An elongated web of paper is perforated along a plurality of transverse lines to provide bands of web areas having relatively high tensile strength which extend generally longitudinally along the web. The lines of perforation can be formed by staggered perforation lines which contain groups of perforations which are separated by unperforated areas or by staggered perforation lines which include groups of perforations having relatively low tensile strength which are separated by groups of perforations having relatively high tensile strength.
