My name is Deepa Puthanparambil.
I am a PhD chemist.
I have been with Bostik for eight years, so
I started working here in 2010 and have been
in charge, or the technical lead, for the
copolyester technology.
We do a lot of work in the flexible packaging.
It’s a big industry.
It’s a big market.
We have seen that copolyester technology works
very well with the flexible packaging because
there are a lot of PET lids.
The anti-fog coating is a new product that
we developed recently within Bostik.
It has very good antiblocking capabilities.
It also has very good slip properties.
With this coating, what happens is the anti-fog
on the coating will actually prevent the water
droplets from forming tiny drops of water.
Instead, it forms a very uniform transfer
and thin film so you can actually see through
the package or the lid and you can see the
food.
You can see the freshness of the food.
The big thing is that we also have included
the anti-fog into the product.
When the end user seals this PET lid onto,
say an APET tray, he can heat seal it with
very minimum temperature, as low as 225 degrees
Fahrenheit, and still get a very good bond
strength of around 800 grams per linear inch
and give a very good peelable seal.
It has also very good clarity, so we chose
the raw materials in such a way that the clarity
is not hindered.
So at the end, when you pack the food and
when you put it into the refrigerator, we
should be able to see the food clearly.
The whole package becomes recyclable.
The consumer, once they use the product or
once they consume the fruits or vegetables
or whatever, they can actually throw the whole
package, along with the lid, into one stream
of recycling, providing one solution to have
a heat seal as well as an anti-fog in one
product.
So it’s completely avoiding or reducing
the manufacturer conversion of this kind of
lidding product by half of it, so it’s just
driving down costs half, by half, because
the second step is completely eliminated by
using our product.
So it is a great big step in the converting
industry.
