consumer goods packages, it can work as an anti-theft
and anti-violation system.
An example of anti-theft/anti-violation system
is sold by MeadWestvaco, called Natralock, which
the main appeal is the safety, made with a blister, a
tear-resistant card and a siren system, that sounds
like on the currently used anti-theft systems, but it is
also activated if the package is twisted or broken, by
the rupture of the ink filaments (Figure 6.20). MWV
uses a printed integrated circuit printed by flexography
with conductive ink, “electronic ink”, graphene-based
(nanomaterial), produced by Vor-ink, which has an
excellent conductivity, competitive cost and flexibility,
that allows the material to be bended without damaging
the electronic circuit. Retailers embed a reusable
electronic module of sound alarm to the circuit, which
sounds if it is removed from the package or if the circuit
is broken.

One of the most intriguing technological races
involving public and private R&D companies is the search
for making the printed electronics available in high
volumes and commercially viable (IAPRI, 2012). The
application of nanotechnology in the electronics industry
has allowed the creation of such small electronics circuits
capable of being printed on thin and flexible surfaces. It
is the born of the
e-packaging
, which involves the printing
of conductive circuits directly on the package material.
E
-packaging goes beyond the radiofrequency identification
– RFID and the monitoring/surveillance via EAS labels –
Electronic Article Surveillance. It does not aim to replace
the current technologies, but aggregate more functionality,
intelligence and interactivity to the current concept of
package, something that the silicon chips do not allow.
In the package sector, the printed electronics
can be used for complex function for many purposes,
from safety systems, temperature registers that tailor
expire date to devices of audiovisual interaction with
the consumer, displaying images, emitting sounds or
even vibrating (powder products dosing). In the field of
pharmaceuticals it can instruct the patient over voice
commands, reminding him of the medication, inform
whether the pharmaceutical has been consumed. In
