Abstract (en)
This invention relates to a tamper-evident tape comprising a transparent backing (12) carrying in order, (1) a discontinuous layer (14) of a barrier material preventing adhesion of the underlying layer (16) to the backing (12); (2) a coloured laminating adhesive layer (16) having a greater affinity to the backing (12) than to any other layer in the tape; and (3) an adhesive layer (18) for aggressively securing the tape to the bag pouch or other substrate to which evidence of tampering is desired, which tape is tamper-evident over a wide temperature range. <IMAGE>
