How to Switch Packaging Suppliers Without Breaking Your Kitchen
A packaging change touches racks, carriers, portioning and staff habits. Here is how to move suppliers without any of those breaking.

Changing packaging supplier is usually presented as a purchasing decision. It is really an operational one, because a container that is a quarter of an inch different in any dimension can stop fitting a rack, a carrier, a bag or a sealing machine — and nobody discovers that until the pallet arrives.
What a size change can break
Storage and racking
Trays sized to a shelf, a rack or a hot cabinet. A slightly larger footprint can mean one fewer per shelf, which multiplies across a shift.
Carriers and bags
Delivery bags, drink carriers and drive-through trays are all fixed. A container that no longer drops into one is a daily irritation.
Sealing equipment
Film sealing tooling is dimension-specific. A different rim profile means new tooling, which turns a packaging change into a capital project.
Portioning and pricing
If the new tray holds ten per cent more, staff will fill it, and your food cost moves. This is the change most often missed.
The sensible sequence
-
Send the new supplier your current packaging
Physical samples, not measurements. Ask them to match the internal dimensions exactly unless there is a reason to change.
-
Ask for pre-production samples
A handful of the actual product before the full run. Load them with your food, put them in your racks, and put them through a real service.
-
Move one format first
Not the whole range. Pick a high-volume, low-risk item, run it for a month, and see what surfaces.
-
Run down the old stock in parallel
Do not switch on the same day the last carton runs out. An overlap of a few weeks removes all the pressure from the transition.
-
Then move the rest
Once one format has run cleanly through a full cycle, the remaining formats are a much lower risk.
Questions to ask before committing
- Will you match my current internal dimensions exactly?
- Can I have pre-production samples before the full run?
- What board and treatment are you quoting, precisely?
- Do you keep the cutting die on file, and what happens to it if I leave?
- What is the realistic repeat lead time once the die exists?
- Is the price delivered to my address, or ex-works?
When you should change the size
Matching the old size exactly is the safe default, but it is not always right. If your current packaging was itself a compromise — a stock size you adapted to rather than chose — a supplier change is the natural moment to fix it.
The way to tell is to ask why the current size exists. If the answer is "it is what our supplier stocks", change it. If the answer is "it fits our racks and our carriers and our portion", keep it exactly.
The most common transition failure is switching every format at once, on the day the old stock runs out, without samples. Every problem then arrives simultaneously, during service, with no fallback. Move one format, overlap the stock, and the whole thing becomes uneventful.
Quick answers
Should I ask a new supplier to match my current tray exactly?
As a default, yes — it removes all the operational risk. The exception is when your current size was itself a compromise you adapted to, in which case a supplier change is the right moment to fix it.
Can I get samples before committing to a full run?
You should insist on it for anything structural. Load them with your actual food, put them through your racks and a real service. Problems that never appear on a specification sheet show up in twenty minutes of real use.
What happens to my cutting die if I change supplier again?
Practice varies, so ask before you order rather than after. It is a fair question and the answer tells you something about how the supplier views the relationship.
