Sealing Tape Roll of a Sealing Tape with Interior Barrier Layers

A sealing tape roll of a sealing tape of flexible, compressible foam with a plurality of interior barrier layers,

• wherein the sealing tape comprises an upper surface, a bottom surface, and two side surfaces connecting the top surface and the bottom surface, and a longitudinal direction, which is parallel to the bottom surface and to the side surfaces;
• wherein the sealing tape is wound up into the sealing tape roll around an axis transverse to the longitudinal direction of the sealing tape in such a way that the top surface of one turn rests against the bottom surface of an adjacent turn of the sealing tape roll, and the side surfaces of the sealing tape form end surfaces of the sealing tape roll, wherein a width of the sealing tape roll is defined as a distance from one end surface to the opposite end surface of the sealing tape roll;
• wherein the sealing tape comprises a plurality of sealing tape sections, which, in an unwound state of the sealing tape, are arranged behind one another in a row in the longitudinal direction, wherein a barrier layer of the plurality of barrier layers is arranged between each pair of adjacent sealing tape sections of the plurality or sealing tape sections;
• and
• wherein the plurality of barrier layers extend over at least 50% of the width of the sealing tape roll between the opposite end surfaces of the sealing tape roll.
