A mono-material PE build keeps the pack inside a kerbside stream instead of a mixed-laminate one, without giving up the seal.
It stands on a base gusset, which is what earns and keeps the facing on a shelf.
About this pack
What It Is for, and What It Has to Survive
Where This Pack Is Used
This is a snack pack, which means it is squeezed in a basket, carried in a bag and opened somewhere other than a kitchen. Nuts and fried snacks also oxidise in daylight, and crisp textures are lost to a little humidity long before the date runs out.
How It Is Built
The base is a folded gusset that opens under the weight of the fill, so the pack stands and faces forward on a shelf. Gusset depth is set from the fill weight and the bulk density together, because the same weight of an aerated product and a dense powder need different bases.
A kraft paper face laminated to a functional inner layer. The paper carries no barrier of its own — everything protective is the liner behind it — so the pack reads as unprocessed in the hand while performing like film on the shelf.
