Coffee packaging that holds the aroma in and lets the gas out
Coffee is the hardest common product to package well. Roasted beans outgas carbon dioxide for days, the volatile compounds that make coffee smell like coffee escape through almost anything, and oxygen stales the oils while the bag sits on a shelf. Coffee packaging has to solve all three at once, and look like its price while doing it.
One-way degassing valves fitted in line
Foil and metallised structures rated 5 of 5 for oxygen
Kraft and recyclable options for speciality brands
Valve, zip, size and print specified together
What coffee does to a pack
Four problems, and none of them can be solved after the bag is made.
It outgasses after roasting
Freshly roasted beans release carbon dioxide for several days. A sealed bag with no way out inflates and can burst its seals; a bag left open to vent lets oxygen in. A one-way degassing valve is the only answer, and it has to be fitted during conversion, not added later.
It loses aroma through the film
The volatile compounds that carry coffee’s smell are small enough to pass through ordinary polyethylene. Holding them needs an aluminium or metallised layer, which is why our coffee structures are built on PET/AL/PE or PET/VMPET/PE rather than a simple laminate.
Its oils go rancid in light and oxygen
Coffee oils oxidise, and light accelerates it. A structure rated 5 of 5 for oxygen barrier that also blocks light gives the twelve-month shelf life a roaster needs for export, where a clear window gives weeks.
It is bought on appearance
Speciality coffee sells on the shelf as much as in the cup. Matt finishes, kraft structures and ten-colour gravure are all available — with the honest trade-off that a kraft paper structure carries less barrier than foil, so the choice is between how it looks and how long it lasts.
Formats for coffee packaging
The formats roasters and tea packers actually order, and why.
Stand-up pouch
The default coffee bag: stands on a shelf, takes a valve and a zip, and available in eight structures from economical to high barrier. Most retail coffee ships in one.
Zipper pouch
For whole bean and loose leaf, where the bag is opened several times. The zip protects what is left after the first opening, which is when most staling happens.
Back seal pouch
Formed on your own line from roll stock at high speed, with uninterrupted print across the front. The economical choice at volume.
Four side seal pouch
Flat, stiff and high barrier — the usual format for single-serve coffee and tea sachets and for sample packs.
Shaped pouch
Die-cut to an outline of your own, in kraft, for speciality brands where the silhouette is part of the identity.
Composite paper can
A board body with a foil lining, for premium ground coffee sold as a gift or a subscription. Prints across the whole body.
Structures that suit it
For roasted coffee with a twelve-month shelf life, PET/AL/PE is the reference structure and PET/VMPET/PE is the lighter, cheaper alternative that reaches the same barrier rating without foil’s weight — see metallized PET film for the difference. Speciality roasters selling through in weeks often prefer Kraft paper/PE for the look and accept the lower barrier. Tea is less demanding on oxygen and more demanding on moisture. Our coffee bag packaging guide works through the whole structure, and materials and structures sets out what each layer does.
What has to be provable
Coffee and tea are food-contact products, so the structure has to be certified as food grade for the market it is sold in — FDA for the United States, GB standards for China, and equivalent declarations elsewhere. We supply the declaration with the order rather than on request. Where the brand claims recyclable or compostable, that claim has to hold in the market where the pack is disposed of, not the one where it is made; export packaging compliance covers what travels with the goods, and quality and compliance lists what we hold.
The rules themselves are public: FDA 21 CFR 177, the US list of permitted food-contact polymers.
Questions we are asked about coffee and tea
Do I need a degassing valve?
For roasted coffee, yes — beans outgas for days after roasting and a sealed bag without a valve will swell and can fail at the seal. Ground coffee outgasses faster and for less time but still needs one. Tea does not.
Can a kraft bag hold coffee for a year?
Not on its own. Kraft paper laminated to PE is a moderate barrier; a twelve-month shelf life needs an aluminium or metallised layer. A kraft outer with a foil ply behind it gives the look and the barrier together, at a higher cost than either alone.
What is the minimum order for a printed coffee bag?
It depends on the structure and the print method. Digital printing makes short runs viable; gravure needs cylinders and so needs volume to justify them. Send the quantity and we will quote both.
Can you fit a valve and a zipper on the same bag?
Yes, and it is the usual specification for retail whole bean — the valve on the back panel, the zip across the top. Both are fitted during conversion.
Which is cheaper, foil or metallised?
Metallised PET, and by a useful margin, at the same barrier rating for most coffee. Foil is specified when the pack is retorted or when a complete light block is required.
Do you print in fewer than ten colours?
Ten is the maximum, not the minimum. Most coffee artwork uses four to six.
Send us the coffee, not just the bag size
Roast level, grind, shelf life and whether it is sold whole bean or ground all change the structure. Tell us those and the quotation comes back against a specification rather than a guess.
Key Information
Coffee packaging has to hold aroma in and let carbon dioxide out at the same time. Roasted beans outgas for days after roasting, so a one-way degassing valve is part of the specification rather than an option.
- Roasted coffee releases carbon dioxide for several days, which is why a one-way valve is fitted.
- Aroma retention needs an OTR below about 1 cc/m²/day, meaning a foil or metallised laminate.
- Common formats are flat bottom, stand-up and side gusset bags.
- Ground coffee needs more barrier than whole beans, because grinding multiplies the surface exposed to oxygen.
- A clear window trades shelf life for shelf appeal, and the window sets the pack's barrier.
Does a coffee bag need a valve?
Yes, if it is filled soon after roasting. Without one the carbon dioxide the beans release inflates and can burst the pack.
What structure suits coffee packaging?
A foil or metallised laminate such as PET/AL/PE or PET/VMPET/PE, which brings the OTR below about 1 cc/m²/day.
Which format should I choose for coffee?
Flat bottom for shelf presence and larger fills, stand-up for flexibility across sizes, side gusset for high-speed lines and traditional retail.
