Side gussets describe the folds; center seal describes the seam
A side gusset is a folded section on each side of the bag that opens as the bag is filled. A center seal is the longitudinal joining seam on the back. A bag can have both side gussets and a center back seam, as shown in the artwork reference, but the two terms describe different parts of its construction.
For coffee or another dry product, show the filled shape you want and how the pack will be displayed. Confirm the base and end-seal construction rather than assuming every gusseted bag has the defined base of a flat-bottom pouch. The seam, folds and filling opening also affect where important text can be placed.
| Term | What it describes | What to show |
|---|---|---|
| Side gusset | The expandable fold at each side. | The folds, their depth and the intended filled profile. |
| Center seal / back seam | The longitudinal seam joining the film at the back. | The seam position and the artwork area beside it. |
| Flat-bottom pouch | A construction with a defined base and side panels. | The base and panel layout if this is the format you require. |
Measure the front width, height and side folds
Provide finished dimensions in millimetres and label how the gusset was measured. The folded-in depth and the expanded side-panel width are different measurements; an unexplained third number can be interpreted in more than one way. A marked photo or drawing is useful when comparing quotations.
Include the actual contents and fill weight, plus any required headspace. Bag volume cannot be selected from weight alone: beans, powder and irregular pieces occupy space differently. Mark which edge will remain open when the bags are supplied and the clearance needed for your filling and sealing equipment.
If the project includes a coffee valve or another feature, identify its proposed position alongside the folds, back seam and seal areas. Review the selected construction and sample with your product before confirming the print layout.
- Label finished front-panel width and total bag height.
- Mark both side folds and state whether the gusset measurement is folded or expanded.
- Identify the supplied seals, filling opening and final seal area.
- Include material structure and total thickness if known, or ask for a proposal.
Arrange artwork across the front, sides and back
The supplied reference shows the layout for a side-gusset center-seal bag: back section, side gusset, front panel, side gusset and the remaining back section. Use it to plan which information belongs on each surface. Request a dimensioned dieline for the selected bag size before preparing production artwork.
Check how artwork will read when the side folds open. Keep key branding, mandatory product information and barcodes within the agreed printable areas, allowing for the actual folds and seams. The PNG reference is a planning image, not an editable production dieline.
For a quotation, list each design and size with its quantity, required features and delivery destination. Confirm the laminate, printing route and sample method before agreeing the production schedule. DDP, FOB and CIF can be discussed with a delivery address or named port.

Buyer questions
Is a side gusset bag the same as a center-seal bag?
No. Side gusset describes the folded sides, while center seal describes the longitudinal back seam. One bag can include both, but a center-seal bag can also have flat sides. Confirm both features on a drawing.
How do I write the gusset dimension?
Label the measurement on a drawing and state whether it is the folded-in depth or the expanded side-panel width. Also provide the finished front width and bag height. Do not reuse a stand-up bottom-gusset measurement without identifying the different structure.
Can side gusset bags be used for coffee?
They can be considered for a coffee project. Share whether you pack beans or ground coffee, the fill amount, packing process and valve requirements so the laminate, dimensions and features can be reviewed together.
Will every side gusset bag stand like a flat-bottom pouch?
That should not be assumed. The base and end seals differ between constructions, and the contents affect the filled shape. If a defined base is essential to your display, compare a flat-bottom bag and review filled samples.
Can I start a custom side gusset inquiry without finished artwork?
Yes. Send the contents, reference size and approximate quantity first. We can confirm the construction and dimensioned layout before final artwork, samples and production are approved.
