Specification

Field of the Invention
This invention relates to the manufacturing of anti-counterfeit Cold
form Blister Laminate and the process of manufacturing there off,
where in hologram design is transferred to the surface of Aluminum
foil. Furthermore,the invention also relates to theCold Form Blister
iaminate,which is a three-layered structure of OPA/ALU/PVC. This
invention relates to the process of manufacturing the anti-counterfeit
three or four-layered laminate blister usedfor packaging in . the
pharmaceutical industry.
Background of the invention and the related Prior Art
Plastic packaging films used in the food industry are normally made
moisture and oxygen impermeable by coating the plastic film on one
side with a relatively thick layer of aluminum. The resulting film is
opaque, and improves the barrier properties of the laminate.
Security laminates are traditionally used to protect pharmaceutical or
health care industry products or packages to ensure that the
underlying items are. not altered. Security laminates are particularly

useful in the health care industry because of the importance of the. end
use of the product. Security laminates are mainly useful as tamper
proof seals on medications, in which some would be life saving. Five
features are particularly important when producing and using security
laminates. First, once applied to an article it is important that, the
feature is difficult to remove to ensure that the underlying item is not
altered or subjected to tampering. Second, a desirable laminate is
difficult if not impossible to duplicate by counterfeiters. Third, if
tampering/duplicating occurs it is important to quickly and accurately
recognize an altered or counterfeit laminate. Fourth, it is important
that manufacturing costs of the laminates are not prohibitively
expensive. Fifth, when used on articles it is important that the
laminate has sufficient.durability to withstand harsh treatment.
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 laminate is
controlled through a series of controlled stages and numerous process
control points so that the output is of the desired quality requirements.

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 raised 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 DE102011107106 relates to the system has a profiled
foil-blister including a carrier surface on both sides. The carrier surface
includes circular guide retainers for head parts of the stoppers on a
side, and positioning and holding elements for conical stopper parts on
another side. A container includes a standing surface, which is
associated to a working plane in an unloading-handling station. The
head parts are freely accessible from an opening side, and the stopper.

parts are received in the positioning and holding elements when the
container is opened for manual . removal of the stoppers. An .
independent claim is aiso included for a blister.
The other document JP2008006710describes the a hologram transfer
foil improved in heat resistance causing no thermal whitening and the
followability to expansion and contraction even if a degree of
expansion is large and capable of transferring a hologram, which is
reduced in the lowering of a hologram effect such as cracking or
whitening and superior in design properties, to a three-dimensional
surface, and a molded product with the hologram using it. The
hologram transfer foil is provided with a base material, a mold release
layer, a hologram layer, a reflecting layer and an adhesive layer. The
mold release layer comprises a melamine resin and the hologram layer
contains a cured material of an ionizing radiation curable resin and
reactive silicone and polyethylene wax. The ratio of the ionizing
radiation curable resin and polyethylene wax of the hologram layer is
100:0.01-10 and the elongation at break of the hologram layer at
23[deg.]C after ionizing radiation curing is 5% or above. The hologram
layer has heat resistance not causing whitening even if it is allowed to
stand for 1 hr in an atmosphere of 150[deg.]C in the state of the
hologram transfer foil.

The patent document JP2007118467states a hologram transfer foil,
which has favorable heat resistance and following-up properties to
expansion and contraction, few cracking and whitening and can
transfer to a three-dimensional surface. This transfer foil consists of a
base material, a releasinglayer, a protectivelayer, a hologram layer, a
reflecting layer and a bonding layer under the condition that the
releasing layer is made of a melamine base resin, the protective layer
is set to include a hardened matter of an ionizing radiation curable
resin M containing a specified urethane (meth)acrylate oligomer and a
(meth)acrylate oligomer and a lubricant, and, at the same time, the
hologram layer is set to include a hardened matter of the ionizing
radiation curable resin M containing, the specified urethane
(meth)acrylate oligomer, a (meth)acrylate oligomer and a reactive
silicon under the condition that the extensions at break after being
cured by ionizing radiation of the protective layer and of the
hologram layer are at least 5% and, the hologram transfer foil has so
high heat resistance as not to develop whitening even at an elavated
temperature.

The patent document US5510171 illustrates a security laminate
comprising a protective layer having first and. second surfaces, an
embossing layer bonded to at least a portion of the second surface of
the protective layer, a reflective layer bonded to at least a portion of
the embossed layer/protective layer composite, an adhesion enhancing
layer bonded to a portion of the reflective layer/embossed
layer/protective layer composite, an adhesive bonded to at least a
portion of the adhesion enhancing layer/reflective layer/embossed
layer/protective layer composite wherein the bond between the
reflective layer and the adhesion enhancing layer and the bond
between the adhesion enhancing layer and the adhesive are each
more tenacious than the bond between the reflective layer and the
embossed layer and further wherein the bond between the adhesive
and the adhesion enhancing layer is more tenacious than the bond
between the adhesive and the reflective layer.

Another method of manufacturing tamper-proof documents is
described in German Patent No. DE-C-29 52 322. A document is
coated with a polyethylene film coated with an adhesive which requires.
cross-linking by ultraviolet irradiation. The resultant laminate provides
a high degree of security, however, it is again prohibitively expensive
to place irradiation equipment and the corresponding protection
equipment at every document distribution location.
The document JP2006001212 states that thea hologram transfer foil,
which gives a transferred article such as a card having a fluorescent
pigment printed layer, which is excellent in anti-forging properties,
anti-altering properties, designability and aethetics and simultaneously

present partially. There is also provided the transfer foil in which a
release layer is formed between the support and the
firsthoiogram forming layer of the security film and an adhesive layer
is formed on the second reflection.
The document JP2006001212 discloses a hologram transfer foil, the
releasability of the protective layer of which is favorable even under
the condition being made of an ultraviolet-curing resin, the frictional
resistance of an image is favorable and. which develops no flash at
transferring and which.can provide a transferred article, which can not
be possible to alter at the transferring to a card or the like and

excellent in anti-forging properties and, in addition, is excellent in
aethetics and designability. In the hologram transfer foil, which is
formed by laminating a releasing layer, a protective layer, a hologram
forming layer, a hologram effect layer and a bonding layer in the order
named, the releasing layer is made of a thermosetting amine resin and
the protective layer is made of an ultraviolet-curing resin including fine
inorganic and/or organic particles.
The other document US4856857describes a transparent-type
hologram comprising a transparent hologram-forming layer and a
holographic effect-enhancing layer comprising a thin transparent film,
the holographic effect-enhancing layer being laminated on the
hologram-forming portion of the transparent hologram-forming layer.
The holographic effect-enhancing layer has a refractive index different
from that of the transparent hologram-forming layer.
Pharmaceutical industry, both domestic and international, is gradually
shifting towards cold form blister from the traditional packaging for
obvious reasons and the same is expected to grow @ 20 % per annum
for next 5 years.
Counterfeits are a major threat for the Pharma industry and the public
health as well and thus the industry is in constant search for newer
and better Anti-counterfeit options.

and in-turn creating a safer and healthier society.
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.
In the meantime, a further improvement in generalization is desired
for a hologram used for an improvement and for prevention of
forgeries in view of its usefulness. To cope with this desire, the
inventors of the present.invention have made an invention concerning
a method in which a hologram transfer aluminium foil is formed
continuously in the course of industrial production.
The design can be customised and further features can be added to
make it more unique and impossible to duplicate.
None of the references described above solve the above-mentioned
problems with security laminates. That is, a security laminate which is
stable, non-reactive, desired functional properties, difficult to imitate

by counterfeiters, readily evidences tampering, and is sufficiently
durable to use on pharmaceutical industry.The invention consists of
certain novel features and a combination of parts hereinafter fully
described and particularly pointed out in the appended claims, it being
understood that various changes in the details may be made without
departing from the spirit, or sacrificing any of the advantages of the

Summary of the invention
This invention relates to the manufacturing of anti-counterfeit Cold
form Blister Laminate and the process of manufacturing there off,
where in hologram design is transferred to the surface of Aluminum
foil. Furthermore, the invention also relates to the Cold Form Blister
laminate, which is a three-layered structure of OPA/ALU/PVC. This
invention relates to the process of manufacturing the anti-counterfeit
three or four-layered laminate blister used for packaging in the
pharmaceutical industry.

Detailed description of the invention with accompanying
drawings
There are many possible embodiments of this invention. The drawings
and description below describe in detail a preferred embodiment of the
invention. The drawings are in three sheets.
Those skilled in the art will recognize the following described features
and improvements of the present invention as well as other and
further objects, features, and advantages that will become apparent
from the following description of presently preferred embodiments of.
the invention given for the purpose of disclosure.
The process of manufacturing the Gold Form Blister laminate blister
laminatedaluminum foil is a newer solution to the Pharmaceutical
industries Counterfeit threat in the area of Cold form Blister packaging
and thus the potential of market catch up and product acceptability is
very high.
The present invention has been made in consideration of the above
. circumstance, and the object of the invention is to provide a hologram
transfer aluminium foil which is easy to identify and difficult to
counterfeit and tamper, an image display element.

The principal object of the invention is to provideanti-counterfeit Cold
Form Blister Laminate.
The other embodiment of the invention is to provide an anti-
counterfeit cold form blister laminate wherein hologram is transferred
to the surface of Aluminum foil.
The other embodiment of the invention is to provide the anti-
counterfeit packaging foil which is made of aluminium.
The other embodiment of the invention is to provide the blister
laminatedaluminum foil which is a three layered structure of
OPA/ALU/PVC.
Still another object of the present invention is to provide the process
of manufacturing the blister laminatedhologram transfer aluminum foil
for packaging the pharmaceutical products.
It is a general object of the invention to provide a security object that
provides strong anti-counterfeiting protection and/or that is easy to
verify.
Such a. hologram, which is difficult to copy, has been used as an
antiforgery means in/various applications; but methods facilitating

copying of the hologram are becoming available recently, and simple
use of a hologram is pointed, out to be insufficient as an antiforgery
means. For that reason, there is an increasing need for a hologram
transfer.foil that gives a hologram improved in antiforgery function and
thus insecurity.
The aim of the present disclosure is to develop and manufacture the
Aluminium foil which has a specific characteristic maintaining the
technical aspects and to protect . end used product from the
counterfeiters.
In the blister laminated hologram transfer aluminum foil,45 micron
Aluminium foil hologram was transferred and adhesive is laminated to
25 micron OPA on hologram side and adhesive is laminated to 60
micron PVC on the other side.
The features and advantages of the present invention will be explored
through the following description and drawings. It should be
understood, however, that the detailed description, while indicating
particular embodiments of the invention, are given by way of
illustration only, and various modifications may naturally be performed

without deviating from the spirit of the present invention.
The fig 1 shows the three layer structure of the blister
laminatedhologram transfer aluminum foil according to the invention;
The fig 2 shows the flow chart of the process of manufacturing, the
hologram transfer aluminum foil according to the invention;
The fig 3 and 4 shows the three layer structure of the blister laminated
hologram transfer aluminum foil according to the invention;
Micro embossing and transfer of the Hologram will occur onto the
transfer substrate. This process is very critical and involves lot of in-
process controls to ensure that the required effect is achieved. This
involves high level well defined embossing and transferring the
impression on the substrate to get the desired effect.
The process for preparing ahologram transfer aluminum foilwhich
comprises a) down gauging the foil stock from 300 microns to 45-60
microns; b) Separation and rewinding into smaller rolls; c) Annealing
of the aluminium foil;d) Lamination of transfer substrate with Treated
Aluminium foil without any adhesive.

If adhesive is used then in step d) Lamination of this Foil with OPA on
Hologram transferred side and with PVC on the other side.
Down gauging the foil stock from 300 microns to 45-60
microns.Aluminium foil can be sourced as the direct roll to gauge
requirement . Rolling of foil stock on 4Hi cold rolling mill with desired
bite and tension to reduce upto 50% per pass. Adjusting the process
parameters appropriately and accurately as the gauge requirement in
this product is very critical. The foil undergoes a rolling cycle through a
pre-designed multiple pass program to finally produce the required
gauge within the gauge tolerance.limit set. With every pass all the
quality parameters are verified for compliance. The online gauge
control ensures that the gauge is uniformly maintained. The finished
pass or the final pass is done with pack rolling. Subsequently the
edges are trimmed and coiling isdone on the re-winder. Separation
and rewinding into smaller rolls is done.
Since this foil subsequently undergoes a lamination procedure the foil
surface is very important to maintain the bond strength and also to
give the required functional parameters compliance.
Annealingof the aluminium foil is a heat process whereby a metal is
heated to a specific temperature /colour and then allowed to cool

slowly. This softens the metal which, means it can be cut and shaped
more easily.
The heat, treatment alters the physical and sometimes chemical
properties of a material to increase its ductility and to make it more
workable. It involves heating a material to above its' glass
transition temperature, maintaining a suitable temperature, and then
cooling. Annealing can induce ductility, soften material, relieve internal
stresses, refine the structure by making it homogeneous, and
improve cold working properties.
The CFB laminate undergoes a deep drawing at the customer end. To
ensure that the forming is structurally intact the process of annealing
is very important. The cycle has to be designed in such a manner
(time and temperature cycle) the drawing and laminate characteristics
are excellent. As expertise in aluminium foil technology and process
parameters is required to effectively design this cycle. Temp soaking
the material at fixed temp for a constant time period to obtain desired
softness level. The cycle designed for this product is Partial annealing
cycle.

The separated foil from the previous process is loaded onto the holding
racks. The annealing furnace is pre-heated to the desired temperature
and then the loaded racks are placed as per the designated position
into the annealing furnace. The temperature of the annealing furnace
is then increased to the desiredtemperature. After the cycle is
complete then the control panel is put off and the temperature is
brought down. The holding racks are removed from the furnace and
allowed to coil gradually at room temperature.
When the Lamination of transfer substrate is treated with Aluminium
foil without any adhesive the partially annealed foil is corona treated
on the laminator and is fed in the first un-winder.The impression
carrying substrate is loaded on the second un-winder. The lamination
is conducted in such a way that the treated foil is in contact with the
anti-counterfeit carrying image substrate. The process is done at a
controlled speed.
When the lamination of this aluminium foil with OPA is on the
hologram transferred side and is attached with PVC on the other side.
The aluminiumfoil with hologram is placed on the first un-winder and
the PVC of the required gauge is placed on the second un-winder and
OPA of the required gauge on the third un-winder. The adhesive is
circulated in both the stations/ glue trays.The web is passed in such a

way that the first surface of Aluminum being coated with adhesive is
non hologram holding side and the same is laminated with PVC after
drying The Hologram holding side is then coated with the adhesive
and dried, before being laminated with transparent OPA.The Quality
parameters tested, verified and confirmed.
Now the laminate is kept undisturbed for set days of curing at room
temperature. Post curing the product is. ready for final sizing as per
customer requirement on slitting machines.
