Abstract
Security tapes are disclosed that include a first substrate having a first major surface covered with a first PSA, a plurality of discrete pieces of second substrate laminated to the first major surface of the first substrate by the first PSA, and a second PSA applied to each of the plurality of discrete pieces of second substrate on a first surface opposite the first substrate. The first substrate is continuous in both the machine and transverse directions. Each discrete piece of second substrate has a length oriented in the transverse direction and may be spaced a distance apart, in the machine direction, from each adjacent piece of second substrate. The first adhesion of the first PSA for each of the discrete pieces of second substrate is less than a second adhesion of the second PSA for a packaging material or packaging carton.
