How to Choose the Right Bread Tray for Your Bakery: A Buyer’s Decision Framework

Specify a bread tray in this order: the temperatures it will see, the product it carries, the clearance and footprint that product needs, how empty trays come back, the equipment it must fit, and only then the price. Each step rules out trays, so you end with a short list of models that can all do the job. Before you order in volume, test a sample on your own dollies, racks and washer with your own product.

Step 1: What temperatures will the tray see?

Write down the coldest room it enters and the hottest wash or steam it goes through, as measured readings. What decides is the maker’s written rating for the exact model, with the unit and the test behind it. Resin reference data only give direction: HDPE has the most cold margin, polypropylene the most heat margin, and standard polypropylene’s listed brittleness temperature is 32°F, so a polypropylene tray needs a written cold rating before it goes into a freezer. The comparison is in comparing HDPE, polypropylene and other tray materials, and if any tray contains recycled resin, see the questions to ask about recycled plastic.

Step 2: What exactly are you carrying?

Measure your tallest product in its packaging and lay out your most common product the way you load it. Note whether it goes into trays warm, frozen or packaged, because that affects airflow and bottom design; choosing between vented and solid bottoms covers that choice.

Step 3: What clearance and footprint does it need?

Two separate numbers. Clearance is the height your product actually gets in a loaded stack, which is less than the depth in the tray’s name; the loaded-stack test for tray depth sets out the loaded-stack test. Footprint is the measured outside length and width, which can differ from the size in the tray’s name; measured dimensions for common tray models lists published figures. If you already run dollies and racks, check the footprint against them here rather than at Step 5: a different footprint means replacing that equipment too, which changes the cost in Step 6.

Product example (checked September 26, 2026). SPF lists its SPF 650 at an overall 26.9 x 22 x 6.1 inches with 5.2 inches of product clearance, 4.10 lb and “100% HDPE resin,” and says “Empty trays drop straight into each other without rotation.” It defines its “1:1” nest ratio as “One empty occupies the nested height of one unit.” As with any tray, check the clearance with your tallest product and compare nested height in inches.

Step 4: How do empty trays come back?

If empties ride back on your trucks, you want stack-and-nest trays, compared by the height each empty tray adds to a nested stack. If trays rarely leave the building empty in bulk, a simple stacking tray can be enough. The comparison method, and why “nest ratio” labels are not comparable across makers, is in comparing stack and nest designs in inches.

Step 5: Will it fit your equipment?

Check the measured tray against every piece of equipment it meets: dolly bases, racks and store fixtures, washer, conveyors and any automated stacker. Ask the equipment maker for its list of compatible trays where one exists. Then order a sample and test it on and under your existing trays, loaded and empty, and through your washer. A tray that fits on paper can still bind, rock or fail to lock.

Dollies, racks, pallets and lids are chosen with the tray, not after it; matching dollies, racks and lids to your trays covers that side.

Step 6: What will it cost over its life?

Price per tray is one line. Loss, breakage, washing, empty returns and how many trays you need in the loop add the rest. Working out the full cost of a tray fleet sets out the calculation, and where bakeries cut tray costs looks at the levers. For who makes what, see comparing tray makers and suppliers.

How do you compare the trays that are left?

Fill in one column per candidate. Every row is something you measure or get in writing; none of it is scored by feel.

Sources for the table: each row corresponds to a step above; the paperwork behind the food contact row is set out on the compliance page linked from Step 1’s materials guide.

A candidate that fails a row that matters to you is out, whatever its price. Among those left, compare trays per trailer and trays per return load, then price.

Which tray should you test first?

The candidate that passes every row and carries the most trays of your product per trailer, loaded and, if empties ride back, on the return. On the same footprint, that comes down to the smallest stack increment that clears your product and the smallest nest increment. Order a sample, run the loaded-stack test and the equipment checks from Step 5, and run it on your real routes before you order a fleet.
