What Is a Commercial Bread Tray? Types, Materials, and Uses Explained

A commercial bread tray is a reusable plastic tray that carries bread and other baked goods from a bakery to stores and restaurants, then comes back empty to be washed and loaded again. Loaded trays stack on one another and ride on dollies and trucks, and stack-and-nest designs take up less height when they travel back empty. It is a delivery container, not a baking pan.

Texas law, which protects these trays from theft, puts it this way: a bakery basket or tray is “a wire or plastic container that holds bread or other baked goods and is used by a distributor or retailer or an agent of a distributor or retailer to transport, store, or carry bakery products” (Tex. Bus. & Com. Code § 17.31).

What does a bread tray do between the oven and the shelf?

It carries the product through every step after baking. Baked product comes off the pans or the cooling line into trays; loaded trays are stacked on dollies, staged and loaded onto trucks; at the store the product goes onto the shelf or stays in the tray on a rack; the driver collects the empties, which ride back to the bakery nested or cross-stacked, go through the washer and return to the line. Each of those stops has its own decisions, laid out in each stop on a tray’s round trip, from dock to store.

Because a tray leaves the building with every delivery, some do not come back. How bakeries measure that loss, and how they mark trays so the owner is clear, is covered in finding where missing trays go.

The same trays work in settings with their own questions: trays in a supermarket’s in-store bakery, trays for a small artisan bakery buying a few at a time, and trays for tortillas, bagels, pastries and donuts.

Three pages look at a tray program as a whole: where tray program costs come from and which to cut first, the rules that touch a tray and the dated changes to watch, and putting a carbon and waste figure on a tray program.

Why can’t a plastic bread tray go in the oven?

Because the plastic’s limit sits below baking heat. Thermo Fisher’s resin reference table gives a maximum use temperature of 248°F for HDPE and 275°F for polypropylene (Thermo Fisher); those are values for labware grades, not ratings for any tray. BAKERpedia puts the usual bakery oven set point at 300 to 570°F (BAKERpedia, oven temperature). Even the low end of that range is above both resin limits, so a plastic tray belongs after the oven, not in it.

Metal pans and sheet pans do the baking. The plastic tray takes over once the product is out of the pan. Why aluminum stays in the oven and HDPE goes on the truck compares the materials side by side.

What types of bread trays are there?

The main split is what happens to the tray when it is empty:

• Stacking trays sit on the tray below whether full or empty, so an empty stack is as tall as a full one.
• Nesting trays drop partway inside one another when empty and take up less height.
• Stack-and-nest trays do both, depending on how the upper tray is turned or which rim position it sits in. Some models have more than one stacking position; Rehrig Pacific describes its 28 x 22 tray as having slots “for fully nested, low stack and high stack positions” (Rehrig Pacific).

Trays also differ in depth, in footprint, and in whether the bottom is open or solid. Display trays built for a store’s rack are a separate group from route trays. What the terms mean, and how to compare trays by height in inches rather than by label, is in what stacking, nesting and cross-stacking mean on a real tray.

What are bread trays made of?

Plastic. The maker sheets checked for this site name two resins, high-density polyethylene (HDPE) and polypropylene. Rehrig Pacific’s bakery tray sheet, for example, lists HDPE for every model but one, which is an “HDPE/PP Blend” (<a href="https://www.rehrigpacific.com/application/files/6517/2919/0456/RPCBakeryTraysOneSheet_8.5×11.pdf”>Rehrig Pacific). Both resins fall under the same federal food contact regulation for olefin polymers, 21 CFR 177.1520; what matters for compliance is the specific grade and its additives, not the resin family.

The practical difference is temperature. HDPE handles cold better and polypropylene handles heat better, which matters if trays go into a freezer or through a hot washer. The materials page linked in the oven section above covers that choice.

What decides whether a tray works in your operation?

Three things the name and the price do not tell you:

• Fit. Trays are sold by a nominal size such as “26 x 22,” but the measured outside dimensions can differ from the name. Your dollies, racks and trailers respond to the measured numbers; published outside dimensions, model by model lists them for a sample of current models.
• Locking. A loaded tray has to seat on the one below it and stay there on a moving truck. Worn rails and rims stop that, and mixed fleets from different molds may not lock together at all. When trays stop stacking, cracking or coming back clean, start from the problem you are seeing and its likely fix.
• Marking. Texas protects trays that carry a “permanently affixed or permanently stamped name or mark” identifying the owner (§ 17.31, linked above). Some marking methods hold up to washing better than others, so ask how a mark is made, not only what it says.

How are bread trays kept safe for food?

That depends on what the tray carries, so this guide sorts tray use into three classes:

1. Direct contact. The tray carries unwrapped product, or product that touches the tray through gaps in its wrapping. FDA’s manufacturing rule defines food-contact surfaces as “those surfaces that contact human food and those surfaces from which drainage, or other transfer, onto the food or onto surfaces that contact the food ordinarily occurs during the normal course of operations” (21 CFR 117.3). A tray under unwrapped bread is one.
2. Packaged transport. The tray carries only sealed, bagged or wrapped product. The packaging is what touches the food; the tray still has to stay clean enough not to soil the packaging or the load.
3. Support and logistics. The tray never carries product: a base under a stack, a spacer, or an empty in storage.

The class belongs to the tray, not the trip. A tray that carries bagged bread on most routes and unwrapped rolls on one is a direct-contact tray, and this guide’s rule is to hold every tray to the strictest class it can reach, because nobody sorts a returned tray by which route it last ran. Most rules on this site that concern cleaning, cracks and allergens are written for direct contact, and each page says where a packaged-only fleet can differ.

For direct-contact trays, the answer is washing and sanitizing between trips and taking damaged trays out of service. For facilities that must register with FDA, the food safety plan’s sanitation controls include “cleanliness of food-contact surfaces, including food-contact surfaces of utensils and equipment” (21 CFR 117.135). Where trays sit in that plan, and what to write down, is set out in the tray’s place in a preventive controls plan.

How does this guide label its rules?

Every rule that a decision rests on is one of four kinds, and each page says which:

• Regulation: quoted and linked to the rule itself.
• Maker’s instruction: quoted from the maker’s own page or document.
• Published guidance: quoted from the agency, code of practice or expert source.
• This guide’s suggested practice: our own reasoning, said in those words, and something to test in your operation.

A link from one page of this guide to another shows where a rule is explained. It does not turn suggested practice into evidence, however many pages repeat the link.

Is a commercial bread tray what you need?

If the job is baking, you need a pan. If the job is moving, storing or delivering baked goods after the oven, you need a tray, and the choice comes down to the temperatures it will see, the product it carries, how empties come back and the equipment it has to fit. Work through those in order with specifying a tray from temperature to price.
