Flat bottom bags—also known as box bottom or square bottom bags—feature four panels and a flat, rectangular base, giving you plenty of room for your custom design to stand out. As the most stable, self-standing bag style, they’re a favorite for coffee packaging and other premium products.

Choose from several resealable closure styles to keep your product fresh after opening. When filling, the wide-open top allows for easy packing and must be heat-sealed to close securely.

The minimum order quantity for flat bottom bags is 1,000 bags per artwork file. This higher minimum helps account for the extra setup and changeover time required for this bag style—our flat bottom pouching line is twice the length of any other, and it takes a little more TLC to produce these beautiful, high-quality bags.

Looking for smaller runs? Create your project in Roastar Design Lab™, which offers a minimum order quantity of just 100 bags.

The flat bottom machine's changeover time is elaborate, so we stick to four standard size offerings that accommodate 6 oz - 16 oz of coffee. If you have a large volume request for a custom size, please connect with our customer service team.

Bag sizes and listed capacities are approximations based on tests using whole coffee beans. Actual capacity will vary depending on your product—density, particle size, and roast style (for coffee) all affect fill volume.

For example, salt weighs more and takes up less space than tea, so capacity can differ significantly between products. We strongly recommend ordering a sample pack to trial fill your product to determine the right size for your needs.

The bag sizes listed (e.g., 5 x 9.25 x 2.875) represent the bag's outer dimensions from edge to edge. For a more accurate idea of your product’s fit, refer to the fillable dimensions, which takes into account space taken up by heat seal areas, the zipper, etc.

The flat bottom pouch is filled from the top and then heat sealed shut above the pocket zipper or tin tie.
