A disposable absorbent article includes first and second end portions, an intermediate crotch portion, and mechanical tape fasteners detachably interconnectable with at least one fastening parts disposed on the outer layer of the first end portion during a position of use. The tape fasteners are arranged on and joined to the inner layer of the second end portion via a producer's bonding face. A user's bonding face is arranged on an opposite user's end part of the tape fastener. Each tape fastener has an odd number of folds in a storage position. Producer's and user's bonding faces are turned towards the inner layer, the user end parts of the fasteners face one another, and the individual fold parts are joined to respective at least one other fold parts by means of a breakable bond in the storage position. The bond is breakable in order to establish the position of use.
