Abstract
The present invention relates to a method for combining RF-EAS circuits with paperboard for producing disposable RF-EAS security tags, or to a method for manufacturing paperboard packaging, such as trays, lids, cartons containers or combinations with an integral RF-EAS security tag.
Claims6
A method for producing EAS security tags or packaging blanks with integral security circuits in which such circuits are completely hidden, comprising:
- a) selecting a first sheet of paperboard material having an outer surface and an inner surface;
- b) printing graphics substantially over the outer surface of said first sheet;
- c) applying to the inner surface of said first sheet a plurality of EAS circuits comprising inductor/capacitor elements tuned to resonate at a specified frequency when exposed to electromagnetic energy;
- d) bonding a second sheet of paperboard material to the first sheet so as to sandwich the EAS circuits therebetween;
- and
- e) converting the bonded sheets of step (d) into separate EAS tags or packaging blanks.
3 more elements
An EAS security tag comprising an EAS circuit sandwiched between two bonded sheets of paperboard material such that the EAS circuit is completely hidden.
