Clamshell Pizza Slice Box

A clamshell pizza slice box holds a single slice in a hinged, snap-shut carton that carries hot and clean through any food court. Slice service moves fast, and the box has to keep up without leaking or falling open. At Apexio Packaging, we manufacture custom clamshell pizza slice boxes in the USA from food-grade kraft and cardboard for slice shops, mall kiosks, stadium vendors and grab-and-go counters. With zero MOQ, free design, a free 3D mockup and free US shipping, you can order one clamshell pizza slice box to test a design or bulk cases for daily service, and every box keeps the same secure hinge and grease-resistant build.

What Is a Clamshell Pizza Slice Box?

A clamshell pizza slice box is a triangular carton with an attached hinged lid that snaps shut over a single slice. Unlike a folded slice wrap, the clamshell has an attached lid on a reinforced hinge, so it closes securely and reopens cleanly for one-hand eating on the move. A front tab or snap-lock holds it shut, ventilation keeps the crust from steaming soft, and a grease-resistant surface stops oil marking a customer’s hands or bag. It is the go-to format for slice-by-the-piece service, and pairs well with our folded custom pizza slice boxes.

Which Brands Use Clamshell Slice Boxes

Clamshell slice boxes suit any high-footfall business selling pizza by the slice. Slice-by-the-piece shops use them as the everyday container, mall kiosks and food courts use them for tidy grab-and-go, and stadium and event vendors use them because customers can carry and eat with one hand. Convenience stores and delivery kitchens use them for single-slice orders, and caterers use them for individually portioned servings. New vendors use the zero-MOQ policy to trial a printed design first, or scale up with our custom mini pizza boxes for personal pies.

Clamshell Slice Box Sizes

Clamshell slice boxes are cut to the slice, and the chart shows the most requested formats.

Box size	Fits	Common use
Standard slice	Regular triangular slice	Everyday slice shops
Jumbo slice	XL New York slice	High-street and stadium
Deep-dish slice	Thick, loaded slice	Chicago-style and gourmet
Extra-wide slice	Wide-cut slice	Food courts and events
Custom die-cut	Any slice geometry	Branded specialty builds

These are common formats, not limits. We die-cut the triangle to your exact slice angle and depth, so a thin New York slice and a thick deep-dish wedge each sit snug with the lid closing flat over the toppings.

Materials and Board Options

Clamshell slice boxes use food-grade kraft or cardboard, chosen for the slice weight and how it travels.

Material / board	Weight	Best for
Kraft board	Food-grade	Eco and natural-look slices
White food board	16-20pt	Bright printed branding
Heavy-duty paperboard	20-24pt	Loaded or deep-dish slices
E-flute corrugated	Thin, ~1/16 in	Extra strength and insulation

Kraft gives a natural, recyclable look, white board prints the brightest for branding, and heavier paperboard or E-flute corrugated adds strength for loaded slices and hot transport. Every board is food-grade with a grease-resistant surface, and FSC-certified stock is available.

Printing Options: Offset, Digital and Flexo

We print clamshell slice boxes by three methods, chosen by run size, board and deadline.

Printing method	Best for	Main strength
Offset	Larger cardboard runs, brand colour	Sharpest detail, steady colour
Digital	Short runs, samples, seasonal art	No plates, fast and affordable
Flexographic	High-volume corrugated and kraft	Cost-efficient at scale

Offset printing gives the sharpest branding for larger runs, digital printing skips plates for fast samples and seasonal art, and flexographic printing covers high-volume kraft and corrugated economically. Because a slice box travels through crowds, we keep the logo bold and readable at a glance, and recommend the best method free.

Colour Options: CMYK, PMS and RGB

Clamshell slice 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, toppings	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 artwork, while Pantone (PMS) matching locks your brand colour so a busy kiosk display stays consistent across every reorder. RGB is screen-only, so we convert files and confirm colour on your proof. Our CMYK, PMS and RGB colour guide explains the systems in plain terms.

Finishes and Coatings

Finishes balance a clean look with the grease resistance a slice box needs most.

Finish / coating	Effect	Best for
Grease-resistant / water-based coating	Blocks oil on the surface	Every slice box
Matte kraft finish	Natural, eco look	Sustainable brands
Gloss coating	Bright, wipeable surface	Colourful kiosk branding
Spot UV	Glossy logo accent	Premium slice brands

A grease-resistant coating is essential because the slice sits directly on the board, while a matte kraft finish suits eco brands and a gloss coating makes colourful kiosk artwork pop. A spot-UV logo adds a premium touch without slowing high-volume service.

Closures, Ventilation and Add-Ons

Add-ons keep the clamshell secure, vented and easy to carry.

Add-on	What it does	Best for
Reinforced hinge scoring	Keeps the lid from tearing	High-volume service
Snap-lock / front tab	Holds the lid shut in transit	Walking and delivery
Ventilation holes	Release steam, keep crust crisp	Hot slices
Grease-resistant liner	Blocks oil soak-through	Loaded slices
QR code print	Menu and loyalty links	Branding on the move

A reinforced hinge stops the lid tearing under repeated use, and a snap-lock tab keeps it shut while a customer walks. Ventilation holes and a grease-resistant liner keep the slice hot and clean, and a printed QR code turns each box into a marketing touchpoint. Pair slices with sides in matching custom take out boxes. Ready to build yours? Get a free quote and a free 3D proof now – email sales@apexiopackaging.com or call +1 (855) 466-6990.

Food Safety: Food-Grade and Grease-Resistant

A clamshell slice box holds hot food directly, so we use food-grade board with food-safe inks and coatings. Since the slice rests straight on the board, we build clamshells from food-grade kraft and cardboard with grease-resistant coatings, never greyboard, and print with food-safe inks. Ventilation holes release steam so the crust stays crisp on the walk out, and the closed clamshell traps heat to keep the slice warm. See FDA food-contact guidance for the underlying standard we build to on every box.

Our Quality Review Before Production

We review every clamshell for hinge strength, closure, print and grease resistance before it ships. We check hinge scoring, snap-lock fit, print registration and slice fit, and we confirm the lid stays shut while a customer walks and stacks cleanly on a counter. Vendors that switch to a properly engineered clamshell pizza slice box report fewer mess complaints and faster service, because the box holds the slice securely without leaking.
