Abstract
A wrapped package carries a transparent overwrap material and a tear tape attached to the overwrap material for effecting tearing of the overwrap material. The tear tape has a layer of adhesive on one side of the tape substrate for adhesion to the overwrap material and a layer of ink arranged to provide visible markings for the tear tape. The ink is applied on the side of the adhesive which is remote from the tape so that when the tear tape is attached to the overwrap material by the adhesive, the second surface of the adhesive and the layer of ink thereon are in contact with the overwrap material and the markings are visible through the transparent overwrap material without viewing through the adhesive and without viewing through the tape.
