Title of the invention: A novel product and process for Registeredl Spot Holography
Metalized Pattern on printed and laminated plastic films
Field of the invention:
The present invention relates to the field of packaging films and labels.
Particularly the present invention relates to the field of flexible packaging films and labels.
More particularly, the present invention relates to a process for coating of flexible packaging
films and labels in a novel and innovative process such that the piracy or copying of the final
product is not possible.
Background and prior art of the invention:
Since the inception of the concept of flexible films, the packaging industry has grown
tremendously. In consonance with the persistent development and utilization of these films, in
conjunction with the manufacturing practices, and innovations, the packaging industry has
grown manifold and still there is a lot of room for improvement as per the requirements and
use worldwide. As the flexible film has varied characteristics, when combined with latest
techniques of production with polymer additions; it provides the means to enhance the
application to broad spectrum of products. Flexible films have an illustrated history in
packaging, and there are continually enhancements and improvements, as well as new
products being marketed.
As there are many polymers which can be utilized in the flexible packaging industry, commonly
the ones which are used are polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC),
polyethylene terephthalate (PET) and biaxially oriented polypropylene (BOPP).
There are varied kinds of film materials which can be combined with different techniques of
manufacturing and technology. Each technique, kind of material, technology has its advantages
and disadvantages, it is imperative to prima facie distinguish amongst them, and then to
analyze the impact on the various combinations and its effect on the film. With every
combination of type of resin, and method of processing, a unique set of characteristics/features
will be produced. Although there were presence of above invention but the piracy could not be
prevented, also the production of such packaging films were costly. This inventions aims to
overcome the above mentioned problems.
The current method of method of processing under the present invention is of Printing
+Holography + Metallizing + Sealing which is done in two layers whereas the other similar
products in the market does it in three layers so the present of method of processing is of
Printing +Holography + Metallizing + Sealing reduces one layer and completes the process in
two layers and not in three layers which is different and comprises security features from the
other similar products in the market.
The other similar products in the market cannot provide this processing of Printing +Holography
+ Metallizing + Sealing in two layers, more over the present invention completes all the above
mentioned process in the first layer itself the second layers is used for sealing only. Under the
present invention process the registered holography and metallizing pattern can be done with
respect to customer's requirement.
The process of present invention process for "Registered / Spot Holography Metalized Pattern"
applied on Printed Substrate increases its attractiveness. The substrate attains a distinctly new
look and appearance from usual packaging film or label.
The invention minimizes chances of duplicity/copy/piracy of packaged product as existing
methods in prior art lack the security features as protected in present invention. Special coating
and ink and holographic effect on substrates, which existing market processes in use cannot
register.
The application part of the invention can be applied on Polyester, BOPP, CPP and all types of
flexible plastic films.

In another embodiment, said process involves special coating and ink and holographic effect on
substrates.
In another embodiment, said process is preferably applied on Polyester, BOPP, CPP and all
types of flexible plastic films.
In another embodiment, the process uses automated machines well known in the art for all
stages of manufacturing the desired product including but not limited to Roto Gravure Printing
for atleast 8 Color printing, self-modified Holographic Machine, Coating machine, metallizer
Plant, laminating machine and Slitting Machine etc.
In another embodiment, the raw materials used are PET, BOPP, low density poly ethylene
(LDPE) films, CPP, paper, ink, coatings, adhesives and any other ingredient as per the
requirement.
In another embodiment, said process provides 2D as well as 3D effects as per the requirement.
In another embodiment, the said process provides for three kinds of spotting work namely plain
metalized, without metalized and printing with hologram.
Advantages of the invention:
Piracy of the finished product will be minimized to a great extent.
The process isolates the use of one extra layer, thus saving raw-material and reducing
manufacturing cost.
"Registered / Spot Holography Metalized Pattern" applied on Printed Substrate
increases its attractiveness.
End product is available in roll form/pouches/sachet form and label form.
Provides an improved registered/spot holography metalized pattern on printed and
laminated plastic.
Can be produced in Polyester, BOPP, CPP and all types of flexible plastic films.
Provides 20 as well as 3D effects.
The present process can produce 4 to 5 tons of the products in one day.
The holographic print can be made as per customer requirement without any barriers.
