Quick answer: A retail case-pack specification defines how sellable cans move from factory to shelf. Buyers need cans per tray, trays per master carton, internal and external dimensions, gross and net weight, barcode hierarchy, lot/date visibility, pallet pattern and compression limits before quoting freight or presenting to retailers.
What buyers need to understand
Start with shelf depth, replenishment method and retailer receiving rules. A shelf-ready tray should protect cans, open cleanly and preserve front-facing presentation. Avoid a carton that saves material but collapses during stacking.
How to specify and verify it
Create an item-and-case master-data sheet. Verify measurements on packed samples, not CAD alone. Test scan quality, handling, drop and compression performance and confirm every packaging level uses the correct GTIN and lot information.
Buyer documentation checklist
| Area | Evidence |
|---|---|
| Specification | Controlled product, pouch, packaging and acceptance requirements |
| Process | Equipment settings, sampling, cleaning and line-clearance records |
| Quality | Lot traceability, deviations, CAPA, release and retained samples |
| Commercial | MOQ, lead time, responsibilities, replacements and change notification |
Common mistakes
- Approving a visual sample without measurable criteria
- Using averages that hide unit-to-unit or lot-to-lot variation
- Printing packaging before specifications and claims are final
- Accepting supplier changes without documented risk review
Frequently asked questions
Should approval be documented by SKU?
Yes. Formula, flavor, strength, count and packaging versions should be traceable to a controlled approval.
Can a supplier certificate replace buyer verification?
No. Certificates support due diligence but must match the material, lot, method and intended finished product.
When should testing be repeated?
Repeat it after relevant supplier, formula, process, packaging or destination-market changes and according to the ongoing control plan.
