16 oz Black Coffee Bags with Degassing Valve – 500 per Box (Bulk Case)

Product Code: CSPZV16B  |  1 lb / 16 oz stand-up pouch  |  500 bags per box  |  Made in the USA

Give your coffee a bold, premium presence on the shelf with the bulk 500-count box of our 16 oz matte black coffee bags with a one-way degassing valve. These flat-bottom, stand-up pouches deliver the sleek, high-contrast look that makes a roaster's brand and label pop — now priced by the case so small roasteries can buy in volume and drop their cost per bag.

Sixteen ounces is the standard 1 lb retail coffee bag size, and the deep black finish reads as modern and upscale — a favorite for single-origin releases, dark roasts, and specialty lines that want to stand apart. Behind the good looks is a Bosch one-way degassing valve that lets CO₂ from freshly roasted beans escape while keeping oxygen out, so you can bag same-day roasts without blowout and deliver coffee at peak freshness.

Why roasters choose these bags

• Sleek matte black finish — a premium, high-contrast backdrop that makes labels, foil stamps, and light-colored artwork stand out on the shelf.
• One-way degassing valve — vents CO₂ from fresh roasts and locks oxygen out, extending shelf life and letting you package immediately after roasting.
• Flat-bottom stand-up design — strong shelf presence at farmers markets, cafes, and retail shelves; the wide base holds a full pound upright.
• Resealable zipper + tamper-proof tab — customers reseal to keep beans fresh at home, while the tear-off tamper tab signals an unopened, professional package.
• Open top for fast filling — load beans quickly, hold the top closed, and run it under a heat sealer just above the zipper and tamper tab for a clean, secure seal.
• Bulk 500-count box — lower per-bag cost, fewer reorders, and headroom to scale as your volume grows.
• FDA-compliant, food-safe, and Made in the USA.

Specifications

How to fill and seal

Stand the pouch on its flat bottom and fill through the open top with up to a pound of beans or ground coffee. Hold the top closed and run it under a heat sealer just above the zipper and tamper-proof tab. The one-way valve handles CO₂ release on its own — no need to burp the bag — so you can package fresh roasts right off the cooling tray.

Frequently asked questions

How much coffee does a 16 oz black coffee bag hold?
Each pouch holds a full 16 oz (1 lb) of coffee — roughly 4¾ cups of whole beans.

What does the degassing valve do?
The one-way valve releases carbon dioxide that fresh-roasted beans give off while preventing oxygen from entering, which keeps your coffee fresher longer and lets you bag beans the same day you roast.

Can I package coffee immediately after roasting?
Yes. The degassing valve is designed exactly for that — it vents CO₂ so freshly roasted coffee won't cause the sealed bag to swell.

How many bags come in the box?
This bulk case (Product Code CSPZV16B) contains 500 bags — ideal for roasters ready to buy in volume and cut their cost per bag.

Are these bags food safe?
Yes. They meet FDA regulations for food packaging and are made in the USA.
