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.
