Selling pizza by the slice is one of the easiest ways to add revenue at a counter, a convenience store, a food truck, or a school cafeteria. But the packaging is where a lot of operators trip up. Grab the wrong pizza slice bag and grease bleeds through onto a customer's hands, the tip of the slice pokes out the end, or the whole thing goes soggy before they get to their car. Get it right and the slice travels clean, stays warm for the short walk, and costs you a few cents.
This guide breaks down pizza slice bag sizes, the paper types that actually resist grease, and how slice bags compare to slice boxes so you can order the right thing for your operation here in Atlantic Canada.
What are pizza slice bags?
A pizza slice bag is a flat paper sleeve, open on two sides, built to hold a single wedge of pizza. The "double-opening" design isn't a gimmick: it lets a counter worker slide a hot slice straight in from one end while the customer eats out of the other. There's no folding, no assembly, and no lid to fumble with during a lunch rush.
Slice bags are the fastest, cheapest way to hand over a single slice. They're the standard at by-the-slice counters, gas station and convenience store hot cases, food trucks, concession stands, grocery hot counters, and cafeterias — anywhere speed matters more than a fully enclosed box.
What size pizza slice bag do I need?
Slice bags come in a small handful of standard sizes, and the right one depends on how big your slices are. Most pizzerias cutting a 16- or 18-inch pie into 6 or 8 slices need the jumbo size; smaller slices from a 12- or 14-inch pizza fit the standard bag.
| Bag size (approx.) | Best for | Typical use |
| 7" x 6½" | Small slices, half-slices, breadsticks | Convenience stores, snack counters |
| 8⅜" x 9" (jumbo) | Standard-to-large slices from 16"–18" pies | By-the-slice pizzerias, food trucks |
If your slices routinely hang out of the bag, size up — a slice with an exposed tip drips and cools fast. If you also sell garlic fingers, breadsticks, or half-slices, the smaller 7" x 6½" bag is a handy second size to keep on the shelf. For sizing on the boxes themselves, our pizza box sizes guide walks through matching box dimensions to your pies.
Grease-resistant vs. plain kraft paper
The single biggest decision is the paper. Slice bags come in two main grades:
Grease-resistant paper is treated so oil doesn't wick through the sheet. This is what you want for anything with real cheese and toppings. It keeps the customer's hands clean, keeps grease off the counter, and looks a lot more professional. It comes in natural (brown) and white.
Plain kraft is untreated and cheaper. It's fine for drier items — a plain cheese breadstick, a bagel, a pastry — but on a loaded slice, grease will show through within a minute or two. If you're bagging pepperoni slices, spend the extra fraction of a cent on grease-resistant.
Slice bags aren't insulated, so they hold warmth only for a short walk to a table or a car — not a delivery run. That's a feature, not a flaw: for by-the-slice sales, you want cheap and fast, not insulated.
Pizza slice bags vs. slice boxes vs. clamshells
Bags aren't your only option, and the right choice comes down to how far the slice is traveling.
Slice bags are cheapest and fastest. Best for eat-now or a short walk. No protection for toppings if the bag gets crushed.
Slice boxes (wedge boxes) are triangular folding boxes that fully enclose the slice. They protect toppings, stack neatly, and present better — worth it if a customer is driving home or you're selling a premium slice.
Slice clamshells are folding containers, often grease-resistant and some rated microwave- and freezer-safe, that lock shut. These suit grab-and-go coolers and reheat-at-home programs in grocery and convenience settings.
A good rule of thumb: bag it if they're eating now, box it if it's traveling. Many counters stock both and let the situation decide.
How many pizza slice bags should you stock?
Slice bags are cheap, take up almost no shelf space, and you never want to run out mid-rush — so most operators keep a comfortable cushion. Estimate your slices sold per week, add a buffer for busy stretches, and order by the case rather than the sleeve. If you want a repeatable method, our guide on calculating par levels for disposables shows how to set order points so you reorder before you hit zero, not after.
Buying by the case also drops your per-bag cost significantly versus small retail packs — the difference adds up fast when you're moving hundreds of slices a week.
