Standup pouches have taken large part of the dogtreats packaging, the great standing
presentation on the shelf will surely give the consumers passing by a fantastic eye-catching
attractiveness.
However, when we are able to apply a clear front window into the dog chews pouch, it will
enable the consumers to judge the dog chews inside just from the outside appearance, so
buying decision is immediately made, and the dogs will just enjoy a long journey taste for
your dog treats. That’s really nice.
However, based on my experiences serving customers, some customers may have some
trouble to realize this clear window standup pouch in a fantastic way, as it has to concern
with window type, artwork design, actual printing effect, dimensions of the pouch and
window, cost effective consideration, etc. As a packaging specialist, it is my duty to help my
customers to realize the pouch they want, so hope what I share in this article be of help for
those persuing what they believe ideal.
1) Artwork
A real great artwork is not just a great one viewed on the computer, it has to be tested
by the effect after actual printing and converting process. As flexible converter, we are
not so professional in artwork design, we just share some of our ideas on this.
a. The dimension of clear window shall be appropriate ratio for the whole layout of
the pouch.

This clear window is just a little smaller ratio compared to the whole pouch.
b. The clear window is better full in a block, not many spots scatted separately, unless
you are sure the consumers may get a clear understanding of the inside content
just through these separate spots.
c. The main color for the pouch shall be not be in conflict with the color of pet food.
2) Metallic background
Sometimes, we may need the backside of the pouch to be metallic, that enables the pouch
to well reflect the lights and present a better looking for the inside pet foods.

This metallic background may be realized by half part metallized polyester film or metallized
CPP film, this will be determined upon particular application. Please reach us for further
ideas once you have doubts within this field.
Compared to the back metallic part, the front clear part will not own the same barrier
property, so in this way, the whole barrier property for the pouch will lower in some extent.
There has been several ways to fight against this situation, just as demetallization the clear
window part, or GL layer is applied in this pouch. There has been different advantages and
drawbacks for these solutions. I will give a further explanation on this topic in the afterwards.
3) Cost effective
One important point is to realize the desired clear window pouch in an effective way,
however different realization may require different costs. It is not easy to judge how much
cost the customer need to pay for this pouch, please reach us for further assistance when
you have troubles in this aspect.
3) Printing
This pouch is realized by rotogravure printing, that will impose vivid eye-catching effect for
the pouch, so the clear window has to be well integrated into the visual effect, to realize a
great fantastic pouch.
4) Lamination

Lamination of this pouch can be realized in different ways, such as dry lamination, extrusion
coating lamination, solvent-free lamination. I will give a further explanation on differences
of these several ways.
What I want to highlight is the influence to the clarity. Compared to solvent-free lamination,
dry lamination will present better clarity, this is essential to figure out once you need a much
clear window.
5) Materials
To achieve a clear window on the pouch, the materials applied have to be in a perfect
combination, the first thing for this pouch is food safe, and then at a cost-effective way.
There are many detailed points on which we may have much further discussions, all these
details work together into a fantastic pouch. I will share with you guys what I experience in
the afterwards.
