Where the Extra Large Rectangular Container works best
At 323×263mm with a 52mm depth, this extra large rectangular container has the most square proportions in our rectangular range. That shape is not accidental — it is optimized for whole-protein roasting, where length and width need to be closer together to fit birds, fish, and large cuts without wasted space or uneven heat distribution.
Whole Bird & Joint Roasting
The near-square format accommodates a whole chicken (up to 2.5kg), a duck, or a large pork shoulder without the bird sitting awkwardly across a narrow long pan. The 52mm sides contain juices and basting liquid throughout the cook. Two containers fit side-by-side in a standard 60cm oven — doubling output per rack. See our baking temperature guide for roasting times.
Holiday & Festive Catering
Thanksgiving, Christmas, and Eid catering operations need containers that handle large protein volumes with minimal handling. This extra large rectangular container goes from oven to table to disposal — no carving dish, no washing up. At 10-12 portions, one container serves a standard family gathering or a small restaurant table. Read our catering container guide for event planning tips.
Bakery & Sheet Cake Production
The 323×263mm surface is large enough for a full sheet brownie or slab cake, while the near-square ratio gives more even baking than a long narrow pan. Bake directly in the container and sell or deliver as-is — no transfer, no breakage. Oven-safe to 220°C. See our commercial bakery container guide for more baking applications.
Meal Prep & Batch Cooking
Meal prep services portion large batches into individual containers directly from the cook vessel. The 3,600ml capacity handles a full lasagne, a tray of moussaka, or a large grain salad for 10-12 portions. Freezer-safe to −20°C — cook, cool, seal, and freeze in the same container. Read our meal prep container guide for production tips.
Restaurant Takeout & Food Delivery
Group orders and family meal deliveries increasingly require containers that hold 8-12 portions in one vessel. This extra large rectangular container handles curries, rice dishes, and baked mains securely — no leakage, stackable up to 4-5 filled units. Read our food delivery container guide for packaging recommendations.
Premium Brand & Custom Packaging
The broad flat base provides a clean canvas for up to 9-color Pantone-matched brand printing. Premium ready meal brands and restaurant chains use this format for signature dishes delivered in branded packaging. See our custom container design guide and foil printing solutions.

Extra Large Rectangular Container questions
How do I prevent sauce leakage during transport?
Use matching aluminum lids and crimp the edges firmly. Fill to no more than 90% capacity, leaving 5mm from the rim.
What’s the safest stacking height when full?
Stack maximum 4-5 containers when full. Use flat surface and avoid tilting during transport to prevent spillage.
Can I roast meat directly without prep?
Yes. Place meat directly in container. No greasing needed. For crispy skin, roast uncovered at 200°C for final 15 minutes.
How long can food stay hot for delivery?
With lid sealed, food maintains 65°C+ for 45-60 minutes. Use insulated bags for longer delivery times.
What’s the best way to reheat for banquets?
Preheat oven to 180°C, remove plastic lids, cover with foil. Reheat 20-25 minutes until internal temp reaches 75°C.
Does it fit standard commercial ovens?
Yes, fits most commercial oven racks. 323mm width allows 2 containers side-by-side in standard 60cm ovens.
