Why weight is not a bag-format specification
It is tempting to begin with a target weight and request a matching bag. That shortcut ignores what is inside. Two dry products at the same declared weight can occupy different filled volumes. Kibble shape, density, fines, headspace and flow can change the pack's filled profile. A bag's needed width, height and gusset therefore come from a review of the product and the intended filled presentation, not from the weight label alone.
The shelf plan supplies the second half of the brief. A brand may need a specific front-facing width, a height limit, a shelf-depth limit, a handle for a particular carrying use or a panel that carries country-specific content. If those constraints are not visible when the format is chosen, they often return later as an artwork or packaging problem.
Make the format choice with the people who will use it
Procurement can collect the commercial inputs: target quantity, route to market, current-pack reference, expected order quantity and the decision required from the supplier. The designer can turn the shelf plan into a panel hierarchy. The technical team can identify what should be checked with the actual product and filling route. This is a short working session, but it produces a far stronger RFQ than a bag type selected from a catalogue image.
| Format family | Question it opens | What to bring to the review |
|---|---|---|
| Stand-up pouch | Should the filled pack stand through bottom geometry while keeping a compact panel plan? | Filled reference, base direction, front/back artwork and opening plan. |
| Flat bottom bag | Will the project use a broader base and distinct panels for shelf presentation or information? | Panel map, shelf depth, feature locations and filled-pack expectation. |
| Side gusset or quad seal | Does the intended pack need expandable sides or structured side-panel communication? | Side copy, coding areas, full geometry and packed-product reference. |
| Flat or three-side seal pouch | Is a compact, flat portion or display route the actual requirement? | Portion plan, opening route, display method and whether reclosure is needed. |
Give the designer a shelf plan, not a slogan
鈥淧remium鈥?or 鈥渆asy to carry鈥?cannot be converted into a usable dieline. A design brief should state which surface faces the shopper, where the pack sits, which panels remain visible, where the user opens it and which information cannot move. The designer should reserve product name, net quantity, barcode and variable code areas before visual elements fill the panel. If a handle, hang feature, window or zipper is proposed, draw its location on the same map.
That map also reveals when a format is being asked to carry too much. A small pack may not have enough uninterrupted panel space for the intended claims and regulatory content. A side panel may disappear at shelf depth. A handle feature can compete with an opening or brand area. These are design decisions with purchasing consequences.
Keep traceability and labelling visible
FDA's U.S. pet-food information describes product identification, net quantity, business identity and ingredient information as core label content. FDA consumer guidance also says dry pet food should remain in its original bag or container when possible because the package can retain information such as the product name, manufacturer, lot number and best-by date. The FDA's storage guidance is limited to consumer handling context and does not establish a material or shelf-life claim for any specific bag.
For projects outside the United States, the brand must confirm the relevant market rules. In every market, the early packaging action is similar: make coding and required information visible in the format brief before artwork and dimensions become fixed.
RFQ checklist
- Describe the product and target net quantity, including any useful physical observations.
- Send current filled-pack images or a product sample plan. State whether the reference is comparable to the new product.
- Provide shelf, display, e-commerce and master-carton constraints.
- Mark the front, back, gusset or side panels, plus opening, closure, feature and coding zones.
- State the filling route if known and distinguish visual sampling from process or seal review.
- Identify the destination market and the quote question you need answered.
Frequently asked questions
Can I choose a pet food bag only by pack weight?
No. Use weight with product characteristics, filled dimensions and the planned shelf presentation.
Does a larger pack always need a handle?
Handle suitability depends on how the filled pack will be carried, the pack geometry and the project review. It should be specified as a use requirement, not assumed from weight.
Can a generic capacity chart confirm my final bag size?
No. A generic chart cannot account for the actual product or intended filled shape. Use a product and pack reference for a project-specific review.
Should date coding be added after artwork is complete?
Reserve the code area before artwork is final. It should be reviewed with the packaging, design and production teams.
Summary
Pack weight gets the conversation started. Product behaviour, shelf use, panel hierarchy and a clear validation question choose the format. Explore bag-format options, review dry pet food packaging, or prepare a format and dimensions RFQ.
