Challenges in packaging
The New Age of
Τhe New Age of
I η the consumer goods industry, the quality of the
packaging is as decisive as the product itself for the
consumer’s buying decision. Modern packaging must
work well in all packaging functions. The package should
provide an attractive presentation, high quality storage and
consumer friendliness and safety with easy opening.
This is the reason why manufacturers in the food-
beverages, cosmetics and pharmaceutical industries have
to meet quite a number of challenges: safe transports and
storage, control of freshness, attractive presentation in the
shelf as well as easy preparation and treatment. The new
advanced solution from Hatzopoulos is the answer
here.
We provide selective weakening of individual packaging
layers for easy opening or perforation of tiny holes to create
a modified atmosphere within the package. The processing
of packaging foils is commonly performed with winding
systems featuring high web speeds of several hundred
meters per minute. High demands to product functionality
are met by Hatzopoulos’ sophisticated laser technology
offering a wide range of customized solutions.
Easy Opening by Selective Micro Weakeningwith the New Advanced
Almost all packaging films (so-called multilayered
structures) consist of several layers. Different layers
have usually different
functions. PET for
example makes for
stiffness and aroma
conservation, PE
for sealing and
tear resistance,
PP for water
vapor tightness
and aluminum
for the general light
protection among others. For easy opening, the supporting
layer is weakened with minimal influence over the other
functionalities. Especially when processing laminated
structures containing Alufoil, the barrier properties of the
packaging are not affected at all. offers excellent
solutions using the various optical characteristics of
the foil layers. Packaging with
laser processed
easy opening
can easily be
opened without
tools.
The Solutions portfolio
� Web-shaped : is the simplest option. For scribing
geometries in web direction, lasers equipped with fixed
optics and beam splitters are the ideal systems. Each laser
beam scribes a path onto the web material via a focusing
optics which may be continuous or non-continuous.
� Cross Web : About 80 % of all packs require cross
web set-up due to the further production process, which
means the easy opening scribing applications are applied
in cross-web direction. Registration marks synchronize
scribing patterns with the printing. This is performed with
lasers equipped with fast scanner heads which compensate
the web speed and can apply a variety of scribing patterns,
even at high speeds, with the so-called on-the-fly method.

This includes scribing of semi circled or lined tear structures
on the edge of a pouch.
� Free Form : Modern and advanced forms
of packaging in order to provide maximum appeal to
the consumers require curves and patterns that are not
geometric. This is the Free Form scribing which can take
place in any given pattern with almost no limitations.
� Straw : Flexible packaging as the most
environmental friendly packaging solution increases market
share to that of rigid and semi-rigid packaging, especially
in the field of beverages. In this market there is a need for
special easy tear area, which will be used for the placement
of the straw. The Straw is the perfect solution for
this application, accurately scribing perfect straw patterns
in any place of the packaging material.
In addition to all the above features our new
system has almost no limitations regarding the offered
web width. We can apply across 1300mm of the
web, offering solutions even for the widest stickpacks
and pouches packaging machines. The application of the
is suitable for laminates of PET/ALU/PE, PET/PE,
PETmet/PE, PP/PPmet, PP/PE and PVC among others.
