Foil container carton specification checklist
Your carton specification records the foil containers in each pack, the space they need, and how your warehouse identifies them. Lids and inner packaging need their own count.
Have a pack size in mind? We can check it against your tray sample and receiving limits.
Discuss your carton packing
Packing specifications for your trays and lids
Your packing specification can allow for trays and lids in one carton, or separate packs for different workstations. That choice affects the count you order and the space you need.
- Nested trays
- Confirm the pieces in each inner pack and the inner packs per carton. A stack should release cleanly without bent rims. A higher count needs a packing check for the exact tray.
- Separate lid packs
- Specify the lid code as well as the tray code. Lid carton quantities can differ from tray carton quantities, so matching carton numbers may leave you short of one component.
- Tray-and-lid sets
- State how many sets you need and how each set reaches your packing team. A lid placed on every tray uses space differently from separate nested stacks.
The carton specification behind your quote
These details let you compare packing proposals on the same basis. Values still under review can stay marked as provisional.
| Field | What you need recorded | Why it matters |
|---|---|---|
| Item identity | Tray code, lid code and relevant drawing or sample reference. | A similar-looking tray may have a different nesting height. |
| Packing count | Pieces per inner pack, inner packs per carton, and total pieces or sets. | Your purchase quantity and warehouse count need the same unit. |
| Inner protection | Bag, sleeve or other agreed inner pack, including separate lid packing. | The packing material takes up space around the product. |
| Outer dimensions | Length, width and height of the closed, packed carton, with units. | The empty carton's internal dimensions are not its shipping dimensions. |
| Weight | Net product weight and gross packed weight, with units. | Gross weight includes the carton and packing materials. |
| Carton construction | Agreed board specification and closure method. | A size match alone does not establish transport protection. |
Carton volume for your freight comparison
For dimensions in centimetres, carton volume in cubic metres is length × width × height ÷ 1,000,000. Use the packed outer measurements.
Courier charges may depend on dimensional weight. FedEx explains dimensional weight; your carrier's service rules determine the calculation. Pallets and loading space need a separate check.
Calculate your carton volume
Carton labels your warehouse can recognise
Your receiving team may work from an item code, barcode or order reference. Recording those details in your carton specification keeps the label consistent with their records.
For a printed carton, the artwork also needs an agreed face, orientation and version.
On the outer carton
Agree the item description, quantity and unit, carton number, and any order or batch reference you require. The exact fields depend on your receiving process.
On an inner pack
If you split cartons for resale or production, decide whether each bag or sleeve needs its own item code and count. An outer label will no longer identify a loose inner pack.
For a barcode
Your approved code and label file provide the reference. Check a printed sample with the receiving scanner before approving the layout. A readable number alone does not confirm that the barcode scans.
Your warehouse's carton requirements
Your warehouse may limit carton weight, pallet height or label placement. Those limits belong in the carton specification before the pack is approved.
For pallet delivery, confirm the footprint, loaded height and gross weight. The pallet itself adds to the shipment; carton volume alone does not describe the loaded unit.
If you have had crushed cartons or difficult-to-separate trays, photos of the unopened carton and nested stack help locate the problem.

Questions before you confirm the carton specification
A new tray, a printed range and a repeat order can each leave a different detail unresolved.
Can I choose a different quantity per carton?
You can request a target count. We need to check it against the tray, nesting height, inner pack and lid arrangement before confirming it. The same count will not suit every tray size.
Is the sample carton the final shipping carton?
Only when that packing arrangement has been agreed. A small sample shipment may use a different carton or count. Your approved carton specification should identify the production pack separately.
Can several sizes or colours share a carton?
Tell us which items you need together and their quantities. Each item needs a clear count and identification method. The mixed arrangement needs review before we confirm the carton.
Can we use the previous order's carton specification?
The previous order is a useful reference. Confirm whether the tray, lid, count, inner pack, label file or delivery destination has changed. A change to any of these may need a new packing check.
Have a tray reference and a target pack size?
Send us what you have: a model number or sample photo, the quantity you would like per carton, and any receiving limits. We can review the remaining carton specification details with you.
