Field of the Invention
This invention relates to a coded aluminium foil and in particular, this invention
- relates to a process for preparing anti-counterfeit aluminium foil and its use for
producing packaging material, decorative foils. The invention relates furthermore to
the use of the counterfeit-proof aluminium foil as claimed in the invention for
producing packaging material, for example for medications.
Background of the invention and the related Prior Art
Packaging industry utilizes aluminium foil individually or as a substrate in
multilayer laminates for its excellent property of resisting the flow of water vapor,
oxygen or for that matter any gaseous identity and acts as a shield between the
product which has been packed and the external atmosphere. Various items to be
packed are evaluated for their sensitivity towards moisture and other items present
in the atmosphere like oxygen etc., and accordingly a structure for the packaging
material is developed.
Aluminium foil is a preferred substrate and used extensively for the packing of
medicines and related products as well in the food and FMCG industry.
Keeping in mind the critical nature of usage ,the manufacturing process of
aluminium foil and aluminium foil based packaging material is controlled through
a series of controlled stages and numerous process control points so that the
output is of the desired quality requirements.

It is important to ensure that there is no pilferage in the interest or the end. user
and health and safety of the consumers.
It is known to make a packaging material (hereinafter called a laminate of the type
described) comprising sheet metal, such as galvanized sheet steel, and aluminium
foil, with an interposed thermoplastic adhesive which, under the application of heat
and pressure, adheres to the foil and sheet metal. The laminated product may be
roll-formed \to desired profile for roofing or wall cladding and, when erected on
structures with the aluminium foil facing inwards, it has good heat insulating
properties because of the low emission of radiant heat from the aluminium foil
surface. The thermoplastic adhesive employed may be polyethylene, with or without
additives, and hereinafter called "polythene".
A structure of/ the type described may have metallic foil likewise adhered to the
second side of the sheet metal so that, when used in a structure, this second metal
foil layer faces outwards, for improved weathering, appearance and/or reflection of
heat, and this second layer of foil may be of aluminium or any other suitable metal.
A difficulty in the manufacture of a packaaging material of the type described is in
obtaining a sufficiently good bond strength within the structure to enable roll-
forming to be carried out satisfactorily and to minimise subsequent damage in the
handling and application of the product.
The demand for counterfeit-proof packaging material, for example for medications,
has grown in recent years to the extent the amount of counterfeit medications has
risen relatively greatly worldwide. These counterfeits can be pharmaceutically
active drugs, but also agents with a placebo effect.

Therefore the attempt is made, to provide packaging materials for the
pharmaceutical industry with holograms. It has been found that even holograms,
although their production is relatively complicated, can be counterfeited with
increasing technical development. These counterfeits can only be characterized or
recognized as such by a specialist since it is difficult for the user of a medication to
ascertain whether the hologram is counterfeit or not if he does not have the
corresponding comparison specimen.
The document CN1693400 relates to a laminated adhesive aluminium foil band is
composed of plastic film layer, aluminium foil layer, central adhesive layer and
adhesive bottom layer. Its preparing process includes such steps as coating
adhesive on top surface of plastic film, attaching aluminium foil to it, and coating
adhesive on the bottom surface of aluminium foil. Its advantages are high
anticorrosion performance, adhesion and tension strength, and easily tearing off.
The other document CN2492493 describes an electromagnetic induction composite
aluminium foil mat used for sealing the open of the bottles consists of a layer of
basic material and a layer of aluminium foil that are laminated with each other
through a layer of adhesion agent , which is crucial to coat a layer of sealing film on
the upper surface of the layer of the aluminium foil and to coat an adhesion layer
on the lower surface of the aluminium foil. Since the upper surface of the layer of
the aluminium foil is coated with a layer of sealing film, the micro holes on the
surface of the aluminium foil are blocked; therefore, the mat has the superior
advantages of anti-moisture, non-permeability, cleanliness, beauty, theft resistance
and fake resistance.
A lot of research work happened in last few years to provide anti-counterfeit

aluminium foil need to be fulfilled for essentially healthcare products which is
clearly understood as priority area.
The patent document DE4435917 states mineral wool product is laminated to a foil
with a glue that is in the form of a reticulate connecting structure between the
fibres in the area of product surface and foil. Also claimed is a method for
producing a mineral wool product by applying a layer of foamed glue onto the
i
product surface, applying the foil to the glue, and curing the glue. Also claimed is
the glue foam used in the method which is a mixture of 10-16 wt.% dry organic
glue, 0.5-1.5 wt.% foaming agent, 0.05-0.3 wt.% foam stabiliser, fireproofing agent
as required and a balance of water, the glue being foamed mechanically
The other document CN201103077 discloses a composite aluminium-foil paper
combined aluminium and paper and used for cigarette packaging. The composite
aluminium-foil paper comprises a layer of lining paper and a layer of aluminium
foil, which are compounded as a whole; the upper local part of the aluminium foil is
overlapped with a laser layer. The three-dimensional laser hologram aluminium-foil
anti-counterfeiting paper provided by the utility model not only has the advantages
and characteristics of freshness preservation and moisture resistance, but also has
the functions of anti-counterfeiting with stereoscopic impression; in addition, the
design proposal of the structure that a required part is partially or wholly
overlapped with a three-dimensional laser hologram layer results in effective
control of production cost, resources conservation and enhance anti-counterfeiting
of products.
According to the document CN101069999 a laser anti-counterfeiting aluminium
foil and its preparation method has been described. The anti-counterfeiting

aluminium foil contains a delomorphic aluminium plating layer, an adhesive layer
and a metal aluminium foil layer overlapping successively. The preparation method
mainly contains washing, gluing, heating, pressing, covering membrane, water or
wind cooling and removing membrane etc. of the aluminium foil. The invention
transfers the laser anti-counterfeiting membrane onto the aluminium foil by using
new-type BOPP. The BOPP substrate membrane has good temperature and age
resistance, soft materials, without coating transparent shape-separating layer and
simple technology. Transferring the anti-counterfeiting membrane onto the
aluminium foil can avoid the laser patterns disappearing or destroying. The whole
membrane has good temperature resistance and is uneasy to craze.
The invention of the document 98/KOL/2005 provides a machine for faster and
economic flipping of an aluminium wire coil. The machine of the present invention
essentially comprises a revolving table, a wire tensioning system, a wire guiding
system, a spool drive and a revolving centre mounted on a sturdy frame.
According to the invention CN2492493 electromagnetic induction composite
aluminium foil mat used for sealing the open of the bottles consists of a layer of
basic material and a layer of aluminium foil that are laminated with each other
through a layer of adhesion agent, which is crucial to coat a layer of sealing film on
the upper surface of the layer of the aluminium foil and to coat an adhesion layer
on the lower surface of the aluminium foil. Since the upper surface of the layer of
the aluminium foil is coated with a layer of sealing film, the micro holes on the
surface of the aluminium foil are blocked; therefore, the mat has the superior
advantages of anti-moisture, non-permeability, cleanliness, beauty, theft resistance
and fake resistance.

A metallic laminate of the type comprising sheet metal, such as galvanized sheet
steel, and aluminium foil, with an interposed thermoplastic, such as polyethylene,
which, under heat and pressure, adheres to the foil and sheet metal, has its bond
strength substantially increased winding it as a coil under tension, the laminate
being heated, before and/or after coiling. Subsequently the coil, while clamped
radially to prevent relative movement of the coil convolutions, is cooled from the
outside, the coiling under tension, the heating and the cooling all causing inter-
layer pressures in the coil which, with the heat, bring about a useful increase in
the bond strengthwhich has been stated in document of patent application
US3970496.
The document US8081359 states that the security object comprises a substrate, a
surface structure and a hologram layer. A volume hologram is arranged in the
hologram layer. The hologram layer is deformed in homogeneously by the surface
structure, which gives rise to readily detectable changes in the reflections from the
volume hologram. These changes can be used to verify the authenticity of the
object. The surface structure can e.g. be applied using intaglio printing techniques
or embossing. Alternatively or in addition to the deformation of the hologram layer
by means of the surface structure, the hologram layer may also be deformed by
embossing.
The other document JP2009116857 provide a low-cost and high-productivity anti
counterfeit measures difficult to fabricate by die picking that is difficult to
determine under a normal visible-light source, capable of obtaining verification
light of a variety of color variations, relative to light source types or the verification
light of vivid color changes in a particular verification method, and further,
producing a high anti counterfeit effects, using a proper pattern. An anti
counterfeit structure includes a particulate fixing layer, having spherical-shaped

particulates and a particulate fixation resin for retaining and fixing the above
spherical-shaped particulates. The particulate fixation resin includes one resin
type or more and is disposed so as not to bury the half height of or greater than the
spherical-shaped particulates. The spherical-shaped particulates are disposed in a
single planar shape over the entire plane, or in an arbitrary shape, with an area
filling rate of 30% or higher and have a mean particle diameter of 2.5 [mu]m or
smaller, with 70% or higher of particles in number, included within a range which
is not smaller than 0.8-fold and not larger than 1.2-fold of the mean particle
diameter.
The document JP60200943 discloses a similar alloy having a composition of, in
weight %, Fe>1.25-1.75, Si 0.41-0.8, Mn 0.10-0.70, balance aluminium and
impurities. This alloy was also developed for use as a fin material within brazed
heat exchangers. The alloy was cast as an ingot, i.e. in a DC semi-continuous
manner, homogenised at 580.degree. C. for 10 hours and scalped. The ingots were
then hot rolled at 525.degree. C. to a gauge of 4 mm and intermediate annealed at
380.degree. C. for 1 hour. They were then subjected to cold rolling down to a gauge
of 0.35 mm, intermediate annealed for a second time in a continuous process with
a temperature of 480.degree. C. for 15 seconds and then final cold rolled to a gauge
of 0.20 mm (i.e. 200 .mu.m), and annealed at 205.degree. C. for 10 minutes to
simulate a paint bake treatment. One specific alloy has a YS of 13.7 kg/mm.sup.2,
(134 MPa), a UTS of 16 kg/mm.sup.2; (157 MPa), but the elongation is reduced to
9%, giving a product of UTS.times.elongation of 1413. The same alloy is also shown
with a YS of 4.916 kg/mm.sup.2, (48 MPa), a UTS of 12.0 kg/mm.sup.2, (118
MPa), and an elongation of 34%, giving a UTS.times.elongation value of 4012. There
is no disclosure of the transverse mechanical properties. However, the treatment of
10 minutes at 205.degree. C. is a recovery anneal. Such an anneal will retain the
anisotropy of the cold working process.

The other document WO02064848 describes a process for manufacturing a foil
product where the alloy composition is, in weight %, Fe 1.2-1.7, Si 0.4-0.8, Mn
0.07-0.20, remainder aluminium and incidental impurities. The alloy is
continuously cast using a belt caster, cold rolled with an interanneal at a
temperature between 280-350.degree. C, and final annealed. The final gauge is 0.3
mm, (300 .mu.m), and the final anneal was a partial anneal by way of a batch
process involving heating the cold rolled product to between 250 and 300.degree.
C. After this processing route the alloy of this disclosure developed a UTS of around
125-160 MPa and elongation values of between about 28 to 14.5%. Multiples of
UTS and elongation can be calculated and they range from 2295 up to 3476. No
data are shown concerning transverse properties or with respect to YS.
According to the document, FR2342169 the invention discloses the treatment of
an anodized aluminium surface with a phosphate solution followed by a treatment
with water not exceding a certain hardness. It does not suggest that said anodized
aluminium foil should be treated with an aqueous bicarbonate solution or that the
temperature of the water should be between 30.degree. C. and 55.degree. C.
The invention in document GB1201641 refers to the amount of electrical contact
between the silver image areas and the metal base, preferably anodized aluminium
could be improved by heating the anodized foil to a temperature of 300.degree.-
400.degree. C. and cooling by immersing in boiling water. It is not concerned with
the preparation of a support for a printing plate and does not suggest that said
anodized aluminium foil should be treated with an aqueous bicarbonate solution or
that the temperature of the water should be between 30.degree. C. and 55.degree.
