Review flat-bottom pouches for coffee, dry foods, snacks, granola, nuts and pet treats when shelf stance and reclosure matter. Product fit, bag dimensions, filled weight and the filling process still require project-specific confirmation.
Coffee
Coordinate the fill, headspace, barrier target, zipper, optional one-way valve, top seal and roast-to-pack timing.
Review coffee bag decisions →Dry Foods, Snacks & Nuts
Confirm bulk density, oils, crumbs or particles, fill line, reclosure, seals, shelf stance and case packing with the actual product.
Review snack packaging →Pet Treats & Pet Food
Match the pouch size, structure, opening, closure, seals and handling to the product and filled weight.
Review pet packaging →Choose the right flat bottom bag configuration
Choose around the product, not a stock size chart. Send the fill weight and a reference pouch if available. We review width, height and base depth together; the same weight of coffee, granola or pet treats can need different dimensions.
Zipper & Filling Opening
Review the standard zipper requirement around filling clearance, top sealing and how customers pour or scoop the product. Confirm the usable opening on a sample.
Optional Coffee Valve
For coffee, review degassing, roast-to-pack timing and valve position. A valve is selected for the application; it is not a default requirement for snacks or pet treats.
Coffee bag and valve options →Material & Appearance
Define the desired appearance, barrier target, heat-seal needs and evidence requirements, then confirm the complete structure. Surface appearance alone does not establish recyclability or a plastic-free package.
Barrier & Shelf-Life Target
Share the product's oils, aroma, moisture sensitivity and intended shelf life. Film structure, seals and the filled package need project-specific review and testing.
Which pouch shape fits your product?
A flat-bottom pouch opens into a rectangular footprint with defined side panels. A stand-up pouch uses a bottom gusset, while a flat three-side-seal pouch has no box-shaped base. Compare the filled package, usable opening, shelf footprint, filling equipment and delivered price before choosing.
Compare Stand-Up Pouches
A bottom-gusset doypack can be an efficient starting point when material use, familiar filling and lower converted-bag cost matter more than a square shelf footprint.
Explore stand-up pouches →Compare Side-Gusset Bags
Side-gusset and quad-seal formats provide vertical capacity for coffee, pet food and bulk dry products, with different panel geometry and closure options.

What is a flat bottom bag?
Flat bottom bag, flat bottom pouch and box pouch commonly refer to a premade flexible package with a rectangular base and defined side panels. Box-bottom and block-bottom wording can overlap in sourcing, so the final dieline, gussets, seals and construction should control the specification. Final dimensions and structure depend on fill weight, product density, barrier, closure and filling method.
- Stable rectangular base
- Five connected artwork panels
- Premade-bag filling and top sealing
- Retail and larger formats subject to product fit
Prevent flat-bottom bag problems that appear after filling
The rectangular base and five-panel artwork create more interfaces to control than a simple flat bag. Confirm the package with the actual product so base deployment, corner seals, panel shape, zipper access, valve clearance, graphics, and case packing are approved as one system.
Base does not open squarely
Review fill volume, product density, bottom geometry, corner seals, material stiffness, filling sequence, settling, and the target shelf footprint.
Review capacity and product fit →Zipper opening is too narrow
Confirm opening width, zipper style, flange position, fill line, top-seal area, consumer access, scoop or pour behavior, and closure cycles.
Compare zipper options →Valve interferes with filling or artwork
Map the valve above the expected product line and away from the zipper, final seal, key graphics, grippers, filling clearance, and case contact.
Review valve placement →Artwork breaks across five panels
Approve panel transitions, folds, gussets, base orientation, registration, seal zones, product bulge and the assembled shelf view.
Prepare five-panel artwork →What we need to quote a custom flat bottom bag
Start with the product, fill weight, preferred dimensions or reference bag, closure, one-way valve requirement, barrier or shelf-life target, artwork count and quantity. Custom flat-bottom pouch orders have a general production baseline of 100 pieces per SKU. Confirm dimensions, structure, printing route, zipper or valve, approvals and quantity for each artwork in the quotation.

- Approximate size or reference bag
- Zipper, valve, window, or opening needs
- Barrier and shelf-life target
- Artwork count and status

Frequently asked questions
What is the MOQ for custom flat bottom bags?
The general production baseline for custom flat-bottom pouches starts from 100 pieces per SKU. Each size and artwork has its own quantity. A paid custom sample can start from 1 piece and is separate from production. Dimensions, material, zipper, valve, window, printing route, price and lead time are confirmed in the quotation.
How long does production and delivery take?
Digital and offset production typically takes 7–10 days for total quantities up to 50,000. Rotogravure typically takes 10–15 days, with larger quantities potentially requiring longer. Material availability, specialty processes and approval timing can affect the schedule. These are production estimates, not door-to-door delivery promises; freight and the delivery date are confirmed separately in your quotation.
How do I choose the size of a flat-bottom pouch?
Share the product, fill weight, current pouch dimensions or a reference photo, and how you fill and seal it. Width, height, base depth, product density, headspace, zipper and any valve affect usable capacity. Confirm fit with the actual product before approving production; a coffee weight does not define the right size for a different product.

What is the difference between a flat bottom pouch and a box pouch?
In flexible premade-bag sourcing, flat bottom pouch and box pouch commonly refer to a bag with a rectangular base and side gussets. Box-bottom and block-bottom wording can overlap across suppliers, so the production specification—dieline, dimensions, gussets, seals, material and features—should define the package rather than the name alone.
When should I choose a flat bottom pouch over a stand-up pouch?
Consider a flat bottom pouch when shelf stance, square facing, five-panel artwork, or case-packing efficiency justify the typically higher converted-bag cost. For many products a stand-up pouch remains the economical starting point. Fill weight, bulk density, closure, quantity, and channel requirements should drive the decision.
Can flat bottom coffee bags include degassing valves and zippers?
Yes. A flat-bottom coffee bag can include a one-way degassing valve and a standard zipper when technically appropriate. Valve type and position depend on the coffee, roast level, packing timing, gas release, bag size, headspace, barrier, zipper, filling and shelf-life target. Placement, filling clearance, top sealing, zipper cycles and valve function must be confirmed for the complete bag.
How should five-panel artwork be approved?
Approve the exact dieline and artwork version across the front, back, two side gussets and base. Keep critical copy, barcodes and key graphics clear of folds, corner seals, zipper and valve clearances, the top-seal area and expected product bulge. Review the assembled and representative filled bag, not only a flat screen proof.
Do custom flat bottom bags require printing plate fees?
Digital and offset printing have no conventional plate fee charged to the customer. Rotogravure plate fees are quoted separately, with any applicable plate-fee policy confirmed for that design. The printing route depends on quantity per SKU, dimensions, material and artwork requirements.
Why does a flat-bottom bag lose its square shape?
The finished shape depends on product density and settling, fill level, base and gusset dimensions, corner seals, material stiffness, zipper and top seal, filling sequence, handling, and case pack. A flat-bottom format should be approved with the actual product rather than from an empty-bag photo alone.
