Abstract
Radio frequency identification labels are made in a high speed and effective manner in a variety of different ways utilizing a number of different sources of RFID inlets, each inlet including an antenna and a chip. A plurality of webs are matched together and RFID labels are die cut from the webs, to produce lined RFID labels. Alternatively linerless RFID labels are produced from a composite web with a release material on one face and pressure sensitive adhesive on the other, the labels formed by perforations in the web.
Claims7
A method of making RFID labels, comprising:
- (a) providing a plurality of RFID inlets, each including a chip, on a first web;
- (b) covering the RFID inlets with a second web, to form a composite web;
- (c) laminating a third web onto the composite web by passing the webs between laminating rolls to sandwich the inlets between the second and third webs without harming the inlets, by providing a recess in at least one of the laminating rolls in alignment with the inlets;
- (d) providing pressure sensitive adhesive on a portion of one of the webs that will be an exterior portion of a label once ultimately formed;
- and
- (e) acting on the composite web so as to form the composite web into labels having a top face, and a bottom face with pressure sensitive adhesive.
