ABSTRACT:
A facial quality paper usable with a center feed roll dispenser. The paper has a plurality of perforations for permitting detachment of paper sections from the loose paper end of the roll. A linear density of six perforations or less per inch are formed along the detachment line to facilitate detachment of each paper section without permitting premature detachment of the paper section within the center feed roll dispenser. Alternatively, control over the separation strength is provided by one or more perforations comprising less than seventy percent of the base line. Separation control is provided by the number or perforations per linear inch, by the total ratio of perforations versus paper along the detachment base line, or by the perforation shape 1.
