You've cupped a new single-origin, locked in the roast profile, and you're ready to release it. Then the packaging question lands: what format, what size, and how many do you have to order to make it work? For a lot of Australian roasters, that last part is where things stall. The release calendar moves fast, with micro-lots, seasonal blends and the odd collaboration, but traditional bag supply was built for big, steady runs. The two don't always line up.
Format is where most of that tension gets resolved. Pick the right one and the bag protects the coffee, sits well on a shelf, and reads the way your brand should. Pick the wrong one and you're either paying for presentation you don't need or skimping on protection you do. Here's how we think about it at KROMA, and the formats worth knowing before you commit.
Start with how the coffee will be used
Before the format, it helps to be clear on a few things about the coffee itself and how someone buys and stores it.
Whole bean or ground changes your barrier and valve needs. Retail shelf or online-only changes how much work the bag has to do visually. A 250g everyday bag has a different job to a 1kg wholesale bag or a 100g sample. And how long the coffee tends to sit between roasting and brewing matters, because that is really a freshness question, and freshness comes down to keeping oxygen and light away from the beans.
Once those are settled, the format almost picks itself.
A note on sizes
Most Australian retail coffee sells in 250g bags. It's the size customers expect and the one your shelf neighbours will be in. 1kg bags are the workhorse for café and wholesale supply. 500g sits in between and is less common, though useful for subscriptions or bigger households. Small 100 to 150g formats are handy for samples, gift packs and letting people try a new origin without committing to a full bag. Settle your size range early, because it shapes which formats and print runs make sense.
The formats worth knowing
Stand-up pouch. The one you see most, and for good reason. It stands on its own, holds a clear front for your label, and works across the common retail sizes. For most roasters releasing 250g and 1kg bags, this is the sensible default. It's flexible, it ships flat, and it gives you plenty of room to print well.
Flat-bottom pouch, sometimes called box-bottom. This is the upgrade in presence. The flat base and squared sides give it a structured, almost boxy shape that holds well on a shelf and photographs cleanly. Five printable panels instead of two means you can run your story down the sides. It costs a little more to make, so it tends to suit brands where the bag is part of the retail experience rather than a back-of-house wholesale item.
Side-gusset bag. The classic coffee "brick", folded at the sides and often topped with a tin-tie. It has a traditional roastery feel that some brands lean into on purpose. Good for whole bean, less common now for premium retail than it once was, but still the right call for the right look.
Quad-seal bag. Four sealed corners, so it stands firm and squares off with crisp edges. It carries weight well, which makes it a strong option for larger wholesale sizes where the bag needs to be sturdy and stack tidily.
There are smaller formats too, like flat pillow pouches for samples and single-serve, but for most retail and wholesale ranges the four above cover it.
Valves, zips and keeping coffee fresh
Freshly roasted coffee gives off carbon dioxide for days after roasting. A one-way degassing valve lets that gas out without letting oxygen back in, which is why nearly every coffee bag has one. If you're bagging soon after roasting, you want it.
Resealing is the other practical detail. A press-to-close zip keeps an opened bag fresh for the customer at home and signals a bit of care. A tin-tie does a similar job with a more rustic look. Neither is essential for every product, but for retail bags that get opened and closed over a week or two, they earn their place.
A quick word on windows. A clear window lets customers see the beans, which some brands love, but it also lets light in, and light degrades coffee over time. If you use one, keep it small, or skip it for anything that will sit under shop lighting for a while.
Finishes and materials
The finish does a lot of quiet work. A matt surface reads modern and understated. Soft-touch lamination adds a tactile richness you notice the moment you pick the bag up. Kraft and natural-paper textures lean into an organic, hand-made feel. Metallic accents catch the light where you want a point of shine. None of these is better in the abstract. It depends on the brand you're dressing.
On materials, the direction across specialty coffee is clear. The industry has been shifting toward single-material structures that are easier to recycle, and away from mixed laminates that are hard to process. Part of that is customer expectation, and part of it is simply the right thing to do. Recyclable and home-compostable options come with real trade-offs around barrier and shelf life, which deserves a proper conversation on its own. We've covered home-compostable coffee bags in a separate piece.
The short-run question
This is the part that trips up the release calendar. Traditional flexographic printing is excellent at volume but expensive to set up, which pushed minimum orders high and made small seasonal runs hard to justify. Digital printing has changed that. It makes runs of roughly 500 to 2,500 bags economically sensible, and even short runs in the low hundreds are possible, just at a higher cost per bag.
In practice, that means you no longer have to over-order a year of bags to launch a single micro-lot. You can match the print run to the lot, refresh the artwork between releases, and keep your range current without a cupboard full of dead stock. For a roaster running a lot of small SKUs, that's the difference between packaging that keeps up and packaging that holds you back.
So which format is right for you?
If you want the short answer: a stand-up pouch with a degassing valve and a zip covers most 250g retail coffee, and it's hard to go wrong with it. From there, a flat-bottom pouch is the one to reach for when shelf presence matters, and a quad-seal earns its keep on larger wholesale sizes.
The fuller answer comes back to your coffee, your customer, and where the bag has to perform. That's the part worth getting right before anything goes to print.
