发明名称 Tamper indicating device
摘要 The invention is a tamper indicating device including a backing. The backing includes a first phase and a second phase. The backing is normally light transmissive, but a peeling force causes the backing to internally delamninate and become opaque. A first skin layer is fixed to the backing wherein the skin layer minimizes pre-destruction of the backing. A layer of adhesive is applied to the first skin layer, which can be affixed to a substrate.
