ABSTRACT:
A non-magnetic material such as cardboard or plastic is used as the packaging material for the product to be protected from counterfeiting. The packaging material is configured as a box whose parts are bonded together by use of a hot-melt adhesive. The adhesive contains magnetic particles such as barium ferrite, and small molten globules of adhesive are applied to appropriate surfaces of the box during box fabrication. The box parts are folded to form the finished box, and under the application of pressure the globules of adhesive spread out and solidify, bonding the box surfaces together. It will be noted that presence of the magnetic particles in the adhesive does not modify the box fabrication procedure in any way, and that the box material may be processed and the box's surfaces printed in the usual manner.
