LAMINATE DEVICE HAVING VOIDED STRUCTURE FOR CARRYING ELECTRONIC ELEMENT, SUCH AS LABEL FOR RFID TAG
First Claim
1. Laminate device comprising:
- a substrate comprising at least one substrate layer, the substrate having a front face adapted to receive printed information,an electronic element, andan adhesive layer disposed on a back face of the substratesuch that the laminate device is adapted to be stuck to an object through at least a portion of the adhesive layer,wherein the substrate layer has a voided structure and a non-voided coating layer is provided on at least one face of the substrate layer.

Abstract
The invention concerns a laminate device with a substrate of the type having a front face adapted to receive printed information, an electronic device such as RFID tag, and an adhesive layer disposed on a back face of the substrate. The laminate device can be made with a voided or microcellular structure. The laminate device also can be made with a compressible and resilient structure such that, after application to an object, the electronic device is at least partially embedded in the substrate. A coated layer, for example, an unvoided coating, can be provided on a surface of the substrate. Advantageously, under electrodischarge testing according to MIL-STD-331B, at least 85% of a group of labels remains operational.
