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.

Claims

1. An RFID label made according to a method 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;

(c) laminating a third web onto the second web by passing the webs between laminating rolls to sandwich the inlets between the second and third webs without harming the inlets, to provide a composite web;

(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 provide the composite web into labels having a top face, and a bottom face with pressure sensitive adhesive.

2. An RFID label made according to a method 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 provide a composite web, by cutting the first web to provide separate sheets each having an inlet, and placing the sheets onto the second web, and by laminating a third web onto the second web by passing the webs between laminating rolls to sandwich the chips between the second and third webs;

(c) providing pressure sensitive adhesive on a portion of one of the webs that will be an exterior portion of a label once ultimately formed;

(d) at least one of verifying the functionality of, or programming of, the chips prior to formation of the composite web;

(e) acting on the composite web so as to provide the composite web into labels having a top face, and a bottom face with pressure sensitive adhesive and;

die cutting opening or recesses in the third web aligned with the inlets, and wherein

(b) is further practiced by insuring that the inlets enter the openings or recesses in the third web.

3. An RFID label made according to a method 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 provide a composite web, by cutting the first web to provide separate sheets each having an inlet, and placing the sheets onto the second web, and by laminating a third web onto the second web by passing the webs between laminating rolls to sandwich the chips between the second and third webs;

(c) providing pressure sensitive adhesive on a portion of one of the webs that will be an exterior portion of a label once ultimately formed;

(d) at least one of verifying the functionality of, or programming of, the chips prior to formation of the composite web;

(e) acting on the composite web so as to provide the composite web into labels having a top face, and a bottom face with pressure sensitive adhesive; and

(f) forming opening or recesses in the third web aligned with the inlets, and wherein

(b) is further practiced by insuring that the inlets enter the openings or recesses in the third web.

4. An RFID label made according to a method 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 provide a composite web;

(c) providing pressure sensitive adhesive on a portion of one of the webs that will be an exterior portion of a label once ultimately formed;

(d) at least one of verifying the functionality of, or programming of, the chips prior to formation of the composite web; and

(e) acting on the composite web so as to provide the composite web into labels having a top face, and a bottom face with pressure sensitive adhesive, further comprising applying a coating of adhesive release material to one of the webs, opposite the pressure sensitive adhesive; and

wherein (e) is practiced by perforating the composite web to form a plurality of linerless labels.
