Packaging
sends a message. What do we want to say to the customer?
Fine estetics of packaging pouches does not only depend on
top design and high quality printing, but as well as, on type of materials used
for pouches manufacturing. In order to preserve maximum quality and freshness
of food there must be a barrier layer which restrains air and humidity flux.
This
layer is mainly made of alum, polyamids, polypropylen and polyester. The
seceond layer, mostly made of polyetylen, gives pouches mechanical
features such as stretchability, tenacity and easy bonding.
