90×90mm · 250ml capacity · Compact square format for sauces, desserts, and individual side portions
Small square foil container for individual sauce portions, dessert cups, and compact side dish formats
At 90×90mm with 38mm depth and 250ml capacity, the QXS9 small square foil container is the most compact square format in our range — sized for individual sauce portions, single-serve desserts, small side dishes, and condiment presentations that require an oven-safe or freezer-safe container at a fraction of the footprint of a standard meal tray. The square shape stacks and stores more efficiently than round or oval formats at the same capacity, and the 38mm depth provides enough volume for a generous sauce portion or a layered dessert. Oven safe to 220°C; freezer safe to −20°C.

Where this small square foil container works best
The QXS9’s 90×90mm footprint is the smallest oven-safe square container in our range — compact enough to sit alongside a main on an airline tray or restaurant plate, yet deep enough at 38mm for a proper sauce portion, a layered dessert, or a hot side dish. At 250ml, it fills the gap between a condiment cup and a full side dish container. The square format stacks and nests more efficiently in refrigerator and storage shelving than round alternatives at the same capacity. For a larger square format, see the QXS10 square container. For a full size overview, see our aluminum container sizes guide.
Individual Sauce Portions
Restaurants and catering operations serving individual sauce portions — gravy, hollandaise, curry sauce, salsa — use this small square foil container to portion, heat, and serve in the same vessel. At 250ml, the QXS9 holds a generous individual sauce portion without the overflow risk of overfilled ramekins. The oven-safe construction allows sauce to be reheated directly in the container at 220°C, eliminating the transfer step from saucepan to serving vessel. Compatible with film lids for chilled retail sauce products. See our catering container guide.
Individual Baked Desserts
The 90×90mm square base provides the correct footprint for a compact individual baked dessert — a brownie square, a caramel custard, a small molten cake, or a fruit crumble portion. The 38mm depth allows for a proper bake depth without the dessert appearing thin or underfilled. The small square foil container goes directly from oven to table without transfer, and the square presentation is visually distinctive compared to standard round ramekins. Oven safe to 220°C. See our baking temperature guide.
Airline & Catering Side Dishes
At 90×90mm, the QXS9 small square foil container fits within the side dish zone of a standard airline meal tray alongside a main container. Airline and institutional catering kitchens use this format for hot side portions — a small potato gratin, a vegetable side, a rice portion — that are cooked, portioned, chilled, and reheated in the same container. The square footprint uses tray space more efficiently than round side dishes at the same 250ml capacity. See our airline catering container guide.
Retail Chilled Sauce & Dip Products
Supermarket chilled and ambient sauce products — portion-pack gravies, dipping sauces, curry bases — use the small square foil container format for single-serve retail SKUs. The 250ml capacity is the standard individual sauce portion for one meal, and the square shape stacks efficiently in refrigerator shelf bays. Film lids provide airtight chilled storage with full print coverage for labelling. The aluminum container communicates a premium tier above standard plastic sauce pots for retail brand positioning. See our custom container design guide.
Meal Kit Sauce & Condiment Components
Meal kit operators packaging pre-portioned sauce and condiment components use this small square foil container for oven-ready sauce portions that go directly into the oven alongside the main protein component. At 250ml, one QXS9 holds a standard single-serve sauce portion. The freeze-to-oven capability allows sauce components to be pre-made, frozen, and reheated in the same container — eliminating prep steps for the consumer. For the main protein component, the QXH3 small baking tray and QXC1 heart shaped container are complementary formats. Read our meal prep container guide.
Premium Brand Compact Portion Packaging
At 90×90mm, every surface of this small square foil container is visible in a retail display or on a plate — the four sides and the base all carry brand impressions. A premium brand using this format for an artisan sauce, a signature dessert portion, or a specialty condiment is investing the full per-unit print cost in a compact, high-visibility package. The square geometry provides a clean, modern aesthetic that differentiates from conventional round sauce pots. Up to 9-color Pantone printing available. See our foil printing solutions.
