An aluminium ply sits between the printed PET and the sealing PE. Foil does not slow light and oxygen down, it stops them, which is what a long stated shelf life actually rests on. Foil and compostability pull against each other, so the two builds are quoted separately rather than sold as one pack claiming both.
A pack of snacks, nuts, dried fruit, powders, tea, confectionery is opened and shut many times before it is finished, so the zipper is specified for repeated cycles rather than for the first one. The base gusset opens under fill weight so the pack stands square on shelf instead of slumping forward.
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.
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.
Made on One Site
Every pouch on this site is produced in our own plant in Shenzhen, China. Film is extruded or sourced to the structure your product needs, printed by gravure from your artwork, laminated, cured, then converted on bag-making lines set up for your format and fill weight. Because those steps sit under one roof, a colour that drifts or a seal that fails a drop test is corrected on the line the same day.
Customising This Pouch
- Size and fill. Standard fills from 100 g to 2 kg, or built to your drawing. Tell us the product and the fill weight and we will come back with a gusset depth and film gauge.
- Barrier. Foil, metallised, transparent high-barrier or compostable, chosen against your shelf life and the market it ships to — not against a house default.
- Closure. Zipper, child-resistant zipper, tear notch, degassing valve, tin tie, hang hole or spout. Specified at the die stage.
- Print. Gravure from vector artwork, CMYK or Pantone, up to ten colours, matt or gloss. Spot UV and soft-touch finishes available.
- Windows. Die-cut to your artwork rather than dropped into a stock position.
Ordering
Send us the product, the fill weight, the format and the quantity per SKU. We reply with a real quote rather than a range. Artwork goes as vector — AI, EPS, PDF or SVG with fonts outlined — and if you have no designer, our graphics team builds the dieline and lays it out for you. You approve a digital proof before any cylinder is engraved, and for colour-critical work we run a press proof on the real substrate first. See the full ordering process.
Certification and Audits
Compostable lines are certified rather than claimed: OK compost HOME and INDUSTRIAL, BPI, DIN CERTCO and AS 5810 against EN 13432, with FDA and LFGB for food contact. The plant is audited to BRCGS, Sedex, BSCI, ISO 9001 and ISO 14001. More about our plant.
