extra large smooth container specifications for wholesale buyers
331×225mm · 3,650ml capacity · Wide shallow format for tray bakes, lasagne, and buffet service
Wide shallow design for tray bakes and easy buffet access
At 331×225mm with 57mm depth and 3,650ml capacity, the QXS5 holds the same volume as the QXS4 but in a fundamentally different shape — wide and shallow rather than narrow and deep. The broader base distributes food across a larger surface area, which suits tray bakes, sheet pan mains, enchiladas, and buffet service where food presentation and easy self-service access matters more than depth. Oven safe to 220°C; freezer safe to −20°C.

Where this extra large smooth wall container works best
As an extra large smooth container, the QXS5 is 83mm wider and 16mm shallower than the QXS4 (248×185mm, 73mm) — producing an almost identical total volume (3,650ml vs 3,600ml) in a completely different form factor. The wider, shallower geometry suits foods that benefit from surface area: browning on tray bakes, even layering on lasagne, and easy self-service access on buffet lines. For a full overview of the smooth wall range, see our smooth wall container wholesale guide.
Lasagne & Layered Tray Bakes
Lasagne, baked ziti, moussaka, and enchiladas are all built in layers that require a wide base rather than depth — the QXS5’s 331mm width creates the correct layer footprint for these dishes at 4–6 portion scale. The 57mm depth holds 3–4 pasta or vegetable layers without compression. The smooth wall construction prevents the layering disruption caused by ridged walls during slicing and service. See our baking temperature guide.
Sheet Pan Chicken & Roasted Vegetables
The 331×225mm footprint provides adequate surface area for sheet pan chicken portions, roasted vegetable medleys, and breakfast casseroles to cook without overcrowding — which causes steaming rather than roasting. The wide base promotes even browning across all pieces simultaneously. Oven safe to 220°C. Requires at least 370mm interior oven width for commercial use. See our commercial bakery container guide.
Buffet & Cafeteria Self-Service
The wide, shallow format maximises food visibility and serving access for self-service lines. Guests can see the full portion spread and reach across the 331mm width without difficulty. The QXS5’s footprint fits standard cafeteria serving line inserts and chafing dish configurations. For hot-hold buffet service, the aluminum construction handles steam table temperatures without warping. Read our catering container guide.
Bulk Meal Prep Wide-Format Mains
Subscription meal prep services use the QXS5 for wide-format bulk mains — sheet pan salmon, chicken thigh trays, and grain salad bases — where the wide flat surface allows faster, more even cooling before portioning than a narrow deep container at the same volume. The 331mm width produces a larger cooling surface area than the QXS4 at equivalent volume, reducing food safety risk at scale. Freezer-stable at −20°C. Read our meal prep container guide.
Institutional & Corporate Catering
Hospital catering, school canteens, and corporate lunch delivery regularly use the 3,650ml format for 4–6 portion mains where a single QXS5 covers a complete table grouping. The wide format reduces the number of containers to transport and manage per service compared to individual-portion containers. Compatible with standard commercial warming trays and delivery carts. See our reliable performance container guide.
Premium Brand Retail Prepared Meals
Family-size prepared meal retail SKUs (4–6 portions) in supermarket chilled sections are the primary commercial application for the QXS5 format. The smooth wall surface provides the largest flat printable area of any medium-large container in our range — giving premium retail brands maximum label real estate for ingredient lists, nutritional info, heating instructions, and brand design. Displayed face-up in chilled cases, the full 331×225mm surface is visible to every passing shopper. Up to 9-color Pantone printing available. See our custom container design guide and foil printing solutions.

Extra Large Smooth Container questions
What foods work best in the wide shallow 331mm container?
Best for lasagne, baked ziti, enchiladas, sheet pan chicken, roasted vegetables, and breakfast casseroles. The wide base promotes even browning and layer presentation. Not ideal for thick soups or tall braised dishes — use QXS4 for those.
Should I use wide shallow QXS5 or deep QXS4 for the same volume?
Both hold ~3,600ml. Choose QXS5 (331×225mm, 57mm) for tray bakes, lasagne, and buffet self-service where a wide surface matters. Choose QXS4 (248×185mm, 73mm) for soups, stews, and deep braised dishes where height is needed.
Will the QXS5 fit in a home oven?
Check your oven interior width first — this container needs at least 370mm (approx. 14.5 inches). Fits most large domestic ovens and all commercial ovens. Safe up to 220°C (428°F). Do not use in microwave.
How much food goes in the 3,650ml wide container?
Fill to 3,000ml (82%) for solid tray bakes and roasted foods. Fill to 2,700ml (74%) for saucy dishes. The wide shallow format means food layers out at lower depth than a narrow deep container at the same volume.
What lids fit the 331×225mm container?
331×225mm aluminum lids for hot buffet transport and steam table service. Film lids available for cold display. Aluminum lids are recommended at this size to prevent bending under load.
Is this extra large smooth wall container safe for hot food?
Yes, FDA approved food-grade aluminum is safe for hot foods. For acidic foods like tomato-based sauces, avoid storing more than 48 hours in the container.
