Black Clamshell Box

A black clamshell box gives takeaway meals a sleek, modern look while holding heat and keeping combos secure from kitchen to customer. Plain white containers make premium food look ordinary, and a matte black carton instantly reads as upscale on a delivery app photo. At Apexio Packaging, we make custom black clamshell boxes in the USA from food-grade board with grease-resistant and leak-resistant liners. With zero MOQ, free design, a free 3D mockup and free US shipping, you can order one sample or a bulk restaurant run and get the same food-safe, on-brand finish.

What Is a Black Clamshell Box?

A black clamshell box is a hinged, one-piece food carton with a lid that folds over and locks shut in a single motion. The hinged lid opens and closes fast, and a snap or tuck lock keeps it shut in transit. Built from black food-grade paperboard or molded fibre, it holds heat, resists grease and presents a clean, modern base for your logo. It suits hot mains and cold desserts alike, and pairs well with a custom togo box for larger orders.

Which Businesses Use Clamshell Boxes

Clamshell boxes suit any food business that wants a premium, contemporary look on takeaway and delivery. Burger joints use them for combos, cafes plate desserts and salads in them, and dark-kitchen brands rely on the black finish to look premium on delivery photos. Food trucks like the fast one-hand close, and meal-prep services use divided versions. With zero MOQ, a new outlet can trial one design first.

Clamshell Box Sizes and Portions

Clamshells are cut to any capacity; the chart maps common ounce sizes to real portions and box dimensions.

Capacity (oz)	Dims (L x W x H)	Fits	Common use
16 oz	5 x 5 x 2.5 in	Snacks, sides, desserts	Single-compartment
24 oz	6 x 6 x 2.5 in	Burgers, wraps	Single main meal
32 oz	8 x 6 x 3 in	Combo meals	Larger hot mains
3-compartment	9 x 6 x 2 in	Meal-prep portions	Divided plates

These are starting points, not limits. We size every clamshell around your exact dish, add dividers for combos, and cut custom dimensions on request, so food sits level and the lid still closes flush.

Food-Grade Materials for Clamshell Boxes

Black clamshell boxes use food-grade paperboard, kraft or molded fibre, each paired with a suitable grease or moisture barrier.

Material / board	Weight	Barrier	Best for
Black SBS paperboard	16-24pt (300-400 gsm)	Grease-resistant	Premium black cartons
Kraft board	14-18pt (250-350 gsm)	PLA or grease-resistant	Eco clamshells
Corrugated (E-flute)	approx 1.5 mm	Optional PE liner	Heavy hot mains
Bagasse / molded fibre	n/a	Natural grease and water resistant	Compostable clamshells

Black SBS gives the sharpest premium finish, while kraft and bagasse suit eco menus, as in our compostable take out containers. Corrugated adds strength for heavier mains. We match the board and barrier to your food free of charge.

Printing Options: Offset and Digital

We print clamshell boxes by two methods, chosen by run size, artwork and deadline.

Printing method	Best for	Main strength
Offset printing	Larger runs, brand-colour consistency	Sharpest detail, steady colour at scale
Digital printing	Short runs, samples, seasonal menus	No plates, fast and affordable

Offset printing uses plates for the crispest logo and steady colour across a big run, ideal on deep black stock. Digital printing skips plates, so a single sample or short seasonal menu stays fast and affordable. Tell us the quantity and we recommend the better route free.

Colour Options: CMYK, PMS and RGB

Clamshell boxes print in CMYK and match exact Pantone (PMS) brand colours, while RGB stays for on-screen design.

Colour system	Use it for	Note
CMYK	Full-colour art, photos, gradients	Standard four-colour print
PMS (Pantone)	Exact logo and brand colours	Identical shade on every reprint
RGB	On-screen design and previews	Convert to CMYK before printing

CMYK reproduces full-colour art, while Pantone (PMS) matching locks a signature colour that pops against black, so every reprint stays consistent. RGB is screen-only, so we convert files and confirm on your proof. Our CMYK, PMS and RGB colour guide explains it simply.

Finishes and Food-Safe Coatings

Finishes set the premium look while coatings do the food-safe work of blocking grease and leaks.

Finish / coating	Effect	Best for
Matte lamination	Deep, modern matte-black look	Premium presentation
Soft-touch lamination	Velvet, upscale feel	High-end delivery brands
Grease-resistant coating	Blocks oil soak-through	Fried and oily food
PE food-safe lining	Leak and moisture barrier	Hot, saucy meals
Spot UV or foil stamping	Metallic or gloss logo on black	Branding accents

Most brands pair a matte-black base with a grease-resistant or PE barrier, then add a foil or spot-UV logo that stands out against the dark board. Soft-touch lamination adds an upscale, tactile feel for premium delivery.

Add-Ons: Vents, Locks and Windows

Add-ons keep the meal secure, release steam and make the clamshell easier to display or carry.

Option	What it does	Best for
Steam vent holes	Releases steam, stops sogginess	Hot fried food
Snap-lock or tuck closure	Keeps the lid sealed in transit	Delivery orders
Compartment dividers	Separates items and portions	Combos and meal prep
Leak-resistant lining	Prevents spills of sauce	Saucy dishes
PLA or PVC window	Shows the food before opening	Desserts and salads

Vent holes stop fried food steaming soggy, while a snap lock keeps sauce sealed on long routes. Dividers organise combos, and a window suits dessert brands, much like our custom takeaway cake boxes.

Food Safety and Heat Performance

Every clamshell box is food-grade and barrier-lined so hot, oily and saucy meals stay contained. Our board is food-contact rated for direct food use, in line with FDA food-contact guidance, with grease-resistant or PE liners matched to the dish. Kraft and bagasse builds are recyclable or compostable, and we confirm microwave suitability where the board and coating allow it, so the clamshell protects the meal and holds up to real service heat.
