Trays are bought on size and unit price and judged on the walk from the counter to the seat. These four decide the walk.

The rim is the structure

A tray is the only foodservice item that has to stay rigid unsupported while being carried one-handed. All of that rigidity comes from the edge.

A rolled or curled rim turns a flat sheet of board into a beam. A plain cut edge has nothing resisting the bend, so a loaded tray flexes in the middle and folds. Ask for the rim by name — it is a die decision and costs nothing per unit once specified.

Ask what the barrier actually is

Hot food attacks a tray from two directions: oil soaking in from below, steam condensing from above. An uncoated board tray goes translucent and limp under chips within minutes, and bare moulded fibre wicks even faster.

“Coated” is not a specification. Get the treatment named on the quote, and understand what adding a plastic barrier does to what the tray can honestly be called at end of life.

Draw the compartments from the menu

Wet and hot next to dry and absorbent is how you turn two good products into one soggy one. A full-height divider between them fixes it.

And make the sauce well deep enough to hold the base of the pot. A shallow well means the pot tips the moment the tray is carried at an angle, which is every time.

Wall angle decides your storage

It sounds like the least important number on the quote. It decides whether fifty trays are one stack under a counter or two.

In a concession stand behind a stand, or in a servery, that is genuine floor space you are paying for. Ask for the nesting height, not just the tray dimensions.

And design the print for the die

Trays are printed flat and formed afterwards. Corners stretch and compress the board, so artwork crossing a corner distorts and a centred logo can end up on a wall.

Insist on a proof shown on the formed tray. A flat proof of a formed product tells you almost nothing.
