The pack (10) of tissue paper rolls comprises a plurality of rolls (R) of tissue paper that are arranged adjacent to one another with the respective axes parallel to, or coinciding with, one another, and are wrapped in a plastic film (1). The plastic film (1) laterally wraps the rolls (R) and is arranged with a first and a second longitudinal edge (1.1; 1.2) folded and closed onto two approximately flat opposite surfaces (11, 13), which are defined by bases of the tissue paper rolls. The plastic film (1) comprises a first transverse edge (1.3) and a second transverse edge (1.4) extending from one flat surface to the other. One of said transverse edges is outside the pack and the other is inside the pack. A line-shaped element (3), having a first end and a second end (3A, 3B), is applied to a surface of the plastic film (1). At least one of the ends of the line-shaped element (3) is arranged near, or in correspondence of, the transverse edge (1.4) of the plastic film (1) outside the pack (10).
