12 oz Coffee Bags
Roaster-grade 12 oz bags with a degassing valve and a resealable top.
Twelve ounces is the retail bag size, and fresh-roasted beans give off gas for days, so the bag needs a one-way valve to let it out without letting air in.
We build 12 oz bags with that valve, a high-barrier film, and a resealable top, then print your label across the whole face.
- One-way degassing valve for fresh-roasted beans
- High-barrier film that blocks oxygen and light
- Resealable tin-tie or zip top
- Box-bottom or stand-up styles, printed full-face
“Low minimums were the whole reason we tried them. 250 pouches to test a flavor, then 5,000 when it took off — same bag, same print, no drama.”
“The valve bags keep our roast fresh and the print quality is better than bags we paid twice as much for. Reorders take one email.”
Why 12 oz and why the valve
Twelve ounces is the standard retail bag for whole-bean and ground coffee in the US, so it's the size most roasters print first. The detail that makes or breaks it is the valve.
Fresh-roasted beans off-gas carbon dioxide for days. Seal them in an airtight bag with no escape and the bag swells like a balloon, sometimes to the point of bursting. A one-way degassing valve lets that CO2 out while keeping oxygen, the thing that goes stale, from getting in. Every serious coffee bag has one.
Film and closure
The film is a high-barrier laminate that blocks oxygen, light, and moisture, the three things that age coffee. On top of the barrier, the closure decides how the customer reseals it:
- Tin-tie: the foldover wire strip, simple and classic
- Zip: a press-to-close seal for a cleaner reseal
- Heat-seal only: cheapest, for single-use or sample sizes
Styles and printing
Box-bottom (also called quad-seal) bags stand square and stack like a brick, which suits shelf display. Stand-up pouches are rounder and cheaper to start. Both print full-face, edge to edge.
We print these digitally, so a small roaster can run a single origin without a five-figure order. Need a refill-and-box system instead? See mylar bags with box. For other sizes and shapes, stand-up pouch custom printing covers the range. Get a quote to price your beans.
