Abstract
The invention relates to method for producing an RFID label. According to said method, a coupling antenna (2) arranged on a web-shaped support material (1) comprising an RFID chip (4) arranged thereon is glued onto a secondary antenna (10). The aim of the invention is to provide an RFID label that can be produced from few recyclable materials with little complication and in an environmentally friendly manner. The invention is characterized in that first the coupling antenna (2) comprising the chip (4) is glued onto a self-adhesive secondary antenna (10) in one step, the secondary antenna having a backing adhesive layer (12).
Claims14
A method of making an RFID label in which a coupling antenna carried on a backing strip with a respective RFID chip mounted thereon is adhered to a secondary antenna wherein first the coupling antenna with the chip is adhered in one step to a self-adhesive secondary antenna having a back face provided with an adhesive layer.
A self-adhesive RFID label with the following features
- a secondary antenna firmly adhered to a coupling antenna carrying an RFID chip,
- the secondary antenna with the coupling antenna and the chip are covered by a face strip having a back face provided with an adhesive layer.
(canceled)
A method of making an RFID label, the method comprising the steps of:
- providing a coupling antenna with a respective RFID chip on a front face of a backing strip having a back face carrying a layer of pressure-sensitive adhesive;
- providing a secondary antenna anchored to a front face of an antenna strip;
- and
- pressing the secondary antenna directly against the adhesive layer on the back face of the backing strip to bond the to secondary antenna to the antenna strip adjacent the coupling antenna and form a laminated inlay comprised of the backing strip with its coupling antenna and RFID chip, the secondary antenna, and the antenna strip.
The method defined in claim 10, further comprising the step of:
- providing a strippable release strip on the adhesive layer on the back face of the backing strip;
- and
- stripping the release strip off the back face of the backing strip to uncover the adhesive layer on the back face of the backing strip before pressing the secondary antenna against the adhesive layer on the back face of the backing strip.
