The construction of
the iLam™ polycarbonate data
page is:
- Rear 150µ white polycarbonate film
- Antenna screen printed on the PC layer
- Contactless chip module
- Elastomer core, which surrounds the contactless
module to provide maximum protection and extends to form
the hinge which is sewn into the passport booklet
- Front 150µ clear laser engraveable
polycarbonate film
The total thickness of the data page is 850µ.
The outer polycarbonate material can be sourced
directly by Brite iD or can be free issued by the passport
printer. .
Subject to the use of suitable inks, the outer
polycarbonate sheets can be printed on the inside, so that
it is not possible to tamper with any of the security printing
Advantages:
- The use of an elastomer core rather than
polycarbonate reduces the material price
- The data page is more flexible, less brittle
and has good solvent resistance
- The elastomer core is extended [at a lesser
thickness] to provide a much more flexible and durable hinge
than one made of polycarbonate. It is not necessary to attach
an alternative paper or other plastic hinge to the outside
of the polycarbonate, which is both unsightly and insecure
compared to the iLam™ page
- The contactless chip is embedded more securely
as it is fully surrounded by the elastomer material. In
a standard polycarbonate data page, the chip usually fits
in a hole in the inner layers, which could allow the chip
to be dislodged and disconnected from the antenna in cases
of severe vibration or knocking
