ABSTRACT:
A film useful in tamper-evident pressure sensitive label applications comprises a blend of incompatible polymers wherein the film is melt extrusion cast and has a cohesive strength less than the adhesive strength of an adhesive material bonded to one surface of the film. The adhesive material has an adhesive strength greater than the cohesive strength of the film so that when the tamper-evident pressure sensitive label has been adhered to a substrate attempted tampering or removal of the label causes at least partial destruction of the film.
