12 oz White Coffee Bags with Degassing Valve – 500 per Box (Bulk Case)

Product Code: CSPZV12W  |  12 oz stand-up pouch  |  500 bags per box  |  Made in the USA

Give your coffee a clean, bright, modern look with the bulk 500-count box of our 12 oz white coffee bags with a one-way degassing valve. These flat-bottom, stand-up pouches offer a crisp matte white canvas that makes colorful labels and bold branding jump off the shelf — now priced by the case so small roasteries can buy in volume and lower their cost per bag.

Twelve ounces is a popular retail coffee bag size — ideal for single-origin releases, sample and gift sizes, and specialty lines where a 1 lb bag is more than customers want. The white finish reads as fresh and approachable, a natural fit for light roasts, seasonal blends, and brands with vibrant artwork that needs a neutral background to shine. Behind the clean look 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

• Clean matte white finish — a bright, neutral backdrop that makes color labels, logos, and illustrative artwork pop 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 the pouch 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 12 oz 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 12 oz white coffee bag hold?
Each pouch holds 12 oz of coffee — roughly 4 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 CSPZV12W) 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.
