Interlocking flap food boxes are one-piece paperboard containers that close with fold-in flaps. The flaps lock together, so you need no glue or tape. Restaurants, cafés, food trucks, bakeries, and caterers use them every day for takeout and delivery.
Knowing the sizes of interlocking flap food boxes is the first step in choosing the right box. The wrong size results in crushed food or meals that slide around in the box. This guide covers capacity, measurements, and other sizing tips.
What Is an Interlocking Flap Food Box?
Interlocking flap boxes are simple fold-top food boxes made from one die-cut sheet of paperboard. Four flaps fold inward from the top edges. The front flap has a tab that slips into a slot to hold the lid shut. Many know it as a Chinese takeout box or paper noodle box.
Makers use kraft or white paperboard for the body. A grease-resistant lining, usually a thin coating, protects the walls from oil and sauce. These paper takeaway boxes carry noodles, rice, and fried meals.

Understanding Capacity and Dimensions
Takeaway box capacity measures how much liquid the box holds, usually in fluid ounces. One fluid ounce equals about 30 milliliters, so a 26 oz box holds roughly 770 ml. Leave headroom so the lid closes easily.
Food box dimensions come in three parts. The top opening is the width and length of the box mouth. The bottom measures the base, which is usually smaller because the walls taper. Height is the vertical distance from the base to the folded rim.
Check which measurement a supplier lists. Top and bottom numbers can differ by up to an inch.
How to Choose the Right Food Box Size
Start with portion size. A box that is too large invites spills, while one that is too small crushes the food. Consider food type next. Saucy dishes need a deeper box and a reliable lining.
Boxes with the same footprint stack neatly in food delivery packaging. Larger boxes offer more print area but take more shelf space. Use this checklist before you order:
- Match the box to a single portion or a shared meal.
- Check sauce volume and choose a leak-resistant lining.
- Confirm the box stacks and fits your delivery bags.
- Leave room for your logo and print area.
- Count flat storage space before ordering in bulk.
Best Foods for Each Box Size
The 8 oz box suits sauces, sides, and desserts. The 16 oz size holds two cups of rice or a generous side. The 26 oz and 30 oz boxes fit noodles, rice bowls, and single entrées. Salads and pasta work well in 32 oz and 45 oz boxes.
Fried chicken, wings, and combo plates fit best in a 66 oz box. Use the 96 oz size for family meals and catering trays. Pick the next size up when a dish includes sauce or sides.
Materials and Features That Matter
Kraft takeaway boxes give a natural, rustic look, while white paperboard offers a clean surface for bright printing. Pick the material that matches your brand and your food.
A PE or PLA coating makes grease-resistant food boxes possible. PLA comes from plant-based material and suits compostable programs, though it needs the right facility. Both coatings help build leak-resistant takeaway boxes.
Check microwave compatibility if customers reheat meals in the box. Ask your supplier for food-safe certification and details on recyclability. Poly-lined paper is recyclable only in facilities that accept it, so avoid broad recycling claims.
