Abstract

A smart label construction that provides a more uniform profile for improved print performance in a thermal label printer. The preferred label design has a layer of pressure sensitive piece of applied over the inlay and beyond the edges of the inlay to provide a smoother step transition and eliminates printing voids along the inlay edges. An oversized adhesive patch is applied at the insert. The adhesive patch extends beyond the perimeter edges of the inlay masking the thickness transition of the inlay base film. Alternatively, a coat of additional adhesive is applied only on the leading and trailing edges of the transponder. Alternatively, a low viscosity adhesive is applied to the backside of the inlay prior to singulating the inlay and inserting it into the label stock. The low viscosity adhesive flows beyond the perimeter of the transponder and fills voids. Alternativley, transponder may compress into a low viscosity of adhesive on the label substrate.

Claims

1. A method of constructing a smart label comprising the steps of:

obtaining label stock having an adhesive layer and an RFID transponder on a first side,

applying an oversized adhesive patch at the RFID transponder,

allowing the adhesive patch to flow beyond the perimeter of the RFID transponder.

2. A method of constructing a smart label comprising the steps of:

obtaining label stock having an adhesive layer and an RFID transponder on a first side,

applying a coat of additional adhesive only on the leading and trailing edges of the transponder,

allowing the additional adhesive to flow beyond the perimeter of the RFID transponder.

3. A method of constructing a smart label comprising the steps of:

obtaining label stock having an adhesive layer;

applying a low viscosity to one side of an RFID transponder; and

applying the RFID transponder to the adhesive layer.

4. A method of constructing a smart label comprising the steps of:

obtaining label stock having a low viscosity adhesive layer;

sinking the RFID transponder into the adhesive layer.
