Laser and specially formulated PE-films allow for controlled tearing. The pouch is constructed with a laminate of an MDO-PE film and a new developed LDPE- based film. The laser preformation in the centre of the side gusset fold of the bag is the starting point for the opening. By weakening the laminate in a controlled way, the material is thin enough to allow for a controlled opening of the pouch but still thick enough to protect the snacks inside.
You open the pouch in the centre, and the opening starts to tear in both directions until it reaches the cross seams that are transverse to make the pouch stable.
“You can open the pouch completely without destroying the shape. The large opening makes it easy to remove the snacks from the pouch”, explains Rothschink.
As the pouch is made from monomaterial PE, it is easy to recycle in the relevant plastics stream.
The pouch was developed in close collaboration with packaging machine producer Rovema.
