Flat Bottom Coffee Bags

Flat bottom coffee bags are engineered in 12 oz (340g) and 2 lb (907g) volumetric bean capacities. High-barrier foil lamination maintains absolute oxygen transmission rate (OTR) protection and moisture vapor resistance to preserve roasted coffee oils and origin aromatics.

To cross-reference lay-flat dimensions, side gusset depth, and top seal clearance before configuring volumetric filling hoppers, check technical specification tables inside each product listing.

• 12 oz Block Bottom Bags: Retail-standard flat bottom pouch structure featuring side gussets and integrated degassing valve.
• 2 lb Block Bottom Bags: High-capacity commercial roasting pouch built for wholesale cafes, bulk bean sales, and foodservice distribution.

One-way degassing valves vent trapped carbon dioxide gas released by fresh roasted beans without allowing ambient oxygen inside. Controlling internal pressure prevents bag rupture during transport while blocking oxygen-induced staling and oil rancidity.

Continuous heat sealers process thick block bottom coffee pouches between 315°F and 365°F (157°C to 185°C). Sealing above the internal pull-tab zipper creates a tamper-evident header seal that maintains barrier integrity until opened by the consumer.

Inventory ships directly from our local Sacramento warehouse so clients can access single units, standard split packs, or master wholesale cases without minimum constraints. Local warehouse stocking eliminates long factory lead times and keeps commercial processing lines operating continuously.
