large smooth wall container specifications for wholesale buyers
248×185mm · 3,600ml capacity · Deepest format in the smooth wall range for stews, braises, and layered dishes
Deep narrow format for layered dishes and braised mains
At 248×185mm with 73mm depth and 3,600ml capacity, the QXS4 is the deepest container in the smooth wall range — 16mm deeper than the next tallest model. The narrow, tall geometry suits dishes built vertically: lasagne with 4–5 layers, slow-braised meats in cooking liquid, thick stews, and deep-fill pies. This large smooth wall container holds its structural integrity under the weight of dense, liquid-heavy contents. Oven safe to 220°C; freezer safe to −20°C.

Where this large smooth wall container works best
The QXS4’s defining characteristic is depth — at 73mm it is 16mm deeper than the QXS5 (57mm) and holds the same 3,600ml volume in a narrower, taller footprint. This makes it the correct choice whenever height matters more than surface area: dishes that build layers, retain cooking liquid, or require a sealed steam environment during oven cooking. For a full overview of the smooth wall range, see our smooth wall container wholesale guide.
Lasagne & Deep-Layered Pasta Bakes
At 73mm depth, the QXS4 accommodates 4–5 full pasta layers with sauce between each — the standard construction for a proper lasagne at 5–6 portion scale. The narrow base (248×185mm) keeps layers compact and structurally intact during slicing, unlike a wide shallow container where layers can slide. The smooth wall construction allows clean vertical cuts from edge to edge without resistance. See our baking temperature guide.
Slow Braises & Stews
Beef stew, lamb shank, chicken cacciatore, and similar braised dishes require depth to keep meat submerged in cooking liquid during long oven sessions. The QXS4’s 73mm depth retains up to 2,500ml of liquid without overflow risk when covered — essential for braises that need 90–120 minutes at 160–180°C. The sealed aluminum lid creates a steam environment that replicates a Dutch oven. See our reliable performance container guide.
Catering & Event Delivery
For catering operations delivering hot mains, the deep format reduces spill risk during transport versus shallow containers — liquid content stays 15–20mm below the rim at recommended fill levels. The 3,600ml capacity covers a 5–6 person table portion in a single container, reducing the number of units to transport and serve per event. Compatible with standard catering delivery racks. Read our catering container guide.
Frozen Meal Production
Frozen ready meal manufacturers use the 3,600ml deep format for family-size SKUs that reheat from frozen — lasagne, shepherd’s pie, fish pie, and moussaka. The depth-to-volume ratio minimises the surface area exposed during freezer storage, reducing freezer burn risk on long shelf-life products. Freezer stable at −20°C. The smooth wall construction provides maximum print surface for retail packaging requirements. See our meal prep container guide.
Deep-Fill Pies & Puddings
Cottage pie, chicken and leek pie, and steamed puddings require genuine depth — a shallow container produces a flat result with poor filling-to-pastry ratio. The QXS4’s 73mm depth allows a proper filling volume beneath a full pastry lid, with 10–15mm of clearance for the pastry to dome during baking. The narrow footprint also suits single-pie formats for catering delivery. See our commercial bakery container guide.
Premium Brand Chilled Ready Meals
Premium supermarket chilled ready meal ranges use the large smooth wall container format to signal quality and generosity — the tall sidewall visible through clear film lids communicates portion depth before purchase. The smooth wall surface provides full print coverage for premium brand design: ingredient windows, chef credentials, provenance stories, and Pantone-matched brand colors. Up to 9-color printing available. The depth creates a perception of substance that flat shallow containers cannot match at shelf. See our custom container design guide and foil printing solutions.

Large Smooth Wall Container questions
What foods work best in this large smooth wall container?
Best for deep-layered lasagne, slow braises, beef stew, lamb shank, deep-fill pies, and family-size pasta bakes. The 73mm depth is the key advantage — it keeps cooking liquid contained and allows full layer construction. For tray bakes and buffet service at the same volume, use the wider QXS5 instead.
Should I use deep QXS4 or wide QXS5 for the same volume?
Both hold ~3,600ml. Choose QXS4 (248×185mm, 73mm) for dishes that need height — layered pasta, stews, braises, pies. Choose QXS5 (331×225mm, 57mm) for dishes that benefit from a wide surface — tray bakes, sheet pan roasts, and buffet self-service.
Can I bake in this large aluminum container?
Yes, oven safe to 220°C (428°F). Remove lids before baking. Deep containers may need 10–15 minutes extra cooking time compared to shallow pans due to the reduced surface area. Do not use in microwave.
How much food goes in the 3,600ml deep container?
Fill to 3,000ml (83%) for baked dishes. Fill to 2,700ml (75%) for liquid-heavy stews and braises — leave at least 20mm from the top for bubbling. The deep format concentrates volume vertically rather than spreading it across a wide base.
What lids fit the 248×185mm container?
248×185mm aluminum lids for hot food transport and oven braising. Film lids available for cold storage and display. Aluminum lids are recommended for this deep format to maintain structural integrity during transport.
Is this large smooth wall container safe for acidic foods?
Yes, FDA approved food-grade aluminum is safe for hot and acidic foods including tomato-based dishes during cooking. For storage after cooking, avoid keeping acidic sauces in the container for more than 48 hours.
