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. The structure is retort capable, which means it survives the pressure and heat of in-pack sterilisation. Where a recycler will take it, the same pack can be built with recycled content or as a mono-material structure; where the shelf life will not allow that, the foil stays.
It is heat sealed rather than reclosable, which is the right call for odour and moisture sensitive dry goods in single portions or in a pack meant to be emptied at once. Mylar is specified where odour and moisture have to stay put in both directions, not just one.
About this pack
What It Is for, and What It Has to Survive
Where This Pack Is Used
Dried herbs, botanicals and supplements, where the aroma inside the pack is the reason the product is worth buying and the pack is specified to hold it in rather than only to keep moisture out.
How It Is Built
Folded once and sealed on the other three edges, with no gusset. It lies flat, posts at letter rates, and prints across one uninterrupted face with no fold crossing the artwork.
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.
