According to the invention, at least one portion of a fold comprises a succession of at least five fold sections in alternation with at least five perforations, and a ratio of the sum of the lengths of the fold sections within said fold portion and a sum of the lengths of the same number of perforations within said fold portion is at least 0.8, preferably at least 1.
