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
Dried or freeze-dried fruit. Dried fruit needs its moisture kept in and hardens without it; freeze-dried needs moisture kept out and goes soggy with it. Both are sticky or fragile enough to make the seal the critical part.
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.
Built on a PET/AL/PE laminate, so an unbroken aluminium layer stops oxygen, light, moisture and odour outright rather than slowing them down. It buys the longest shelf life we can specify and gives up kerbside recyclability, which is a trade worth making deliberately.
