A tamper evident label is provided. The tamper evident label broadly includes a base ply of pressure-sensitive material and a top ply of pressure-sensitive material. The base ply and the top ply are laminated together to form the tamper evident label The base ply includes a first portion and a second portion. The second portion of the base ply includes internal cuts and deadened adhesive. The top ply includes a tab portion defined by tab cuts. The tab portion of the top ply and the region between the internal cuts of the base ply are configured to be removed from the tamper evident label to create visual evidence of tampering. Further, a method of constructing a tamper evident label and a method of using a tamper evident label are provided.

The present invention provides a process for incorporating a wireless device into a plastic container as part of the steps of manufacturing the container. The plastic container can be a flexible plastic bag and are formed of one or more sheets, generally two or more sheets of plastic film or a rigid plastic container such as a tub or tote. The bags are formed by sealing together adjacent edge portions of each film layer. One embodiment of the present invention is to incorporate a wireless device between the edge portions of the film(s) before or during sealing so that the wireless device becomes permanently sealed into the film material but is isolated from both the bag interior and the outside environment. Another embodiment is to incorporate the wireless device onto or into a plastic component that is sealed to the container, such as a nipple or port, so that the wireless device becomes permanently sealed to the container but is isolated from both the container interior and the outside environment.

Label apparatus having identification tags and tamper evident pattern release layers and methods of producing such labels are disclosed. An example apparatus includes a first substrate, a first pattern of adhesive, a tamper-evident release layer, a second pattern of adhesive, a tag, a third pattern of adhesive, and a second substrate. The first pattern of adhesive includes a first adhesive. The first pattern of adhesive and the tamper-evident release layer are disposed on the first substrate. The second and third patterns of adhesive include a second adhesive. The second pattern of adhesive is disposed on the first substrate and surrounded by the first pattern of adhesive. The tag includes a remaining portion coupled to the first pattern of adhesive and a removable portion coupled to the second pattern of adhesive. The third pattern of adhesive is coupled to the tag, the first pattern of adhesive, and the second substrate.

Labels having identification tags and tamper evident pattern release layers and methods of producing such labels are disclosed. An example method includes moving a first substrate in a direction. The first substrate has a first side opposite a second side. The first side has a first adhesive and a pattern release layer. The method also includes coupling a third side of a tag to the first side of the first substrate. The tag includes the third side and a fourth side opposite the third side. The method also includes mating transfer tape of a second substrate over the first side and the fourth side. The second substrate includes a liner layer and the transfer tape. The transfer tape is to be positioned immediately adjacent the tag.
