Flexible pouch films
Stand-up pouches, from the kraft-and-foil coffee bag to mono-material film you can drop off at a store. What barrier the pouch needs decides what it is made of, and what happens to it afterwards.

How to choose in this family
foil for the longest shelf life, metallised for matte black, mono-PE for a recyclable claim, compostable for short supply chains, iridescent when the film is the idea

Kraft / PET / aluminium / PE pouch
The classic coffee pouch: kraft face outside, full barrier inside.

Kraft / PLA compostable pouch
Small-batch coffee, tea and dry goods sold through a short supply chain.

Matte BOPP / metallised PET / PE pouch
The matte black (or matte anything) coffee pouch.

Mono-material PE pouch
Brands that need a recyclable claim on the back panel and can live with a softer hand.

Metallised and iridescent film
Pouches where the film itself is the whole idea.

One-way degassing valve
Required for whole-bean coffee. Fresh roast gives off CO₂ for days.

Press-to-close zipper
Reclosure on coffee, snack and dry-goods pouches.

Tin tie
Reclosure with a craft read, usually on kraft-face bags.
