Karat Pizza Boxes 12" x 12" x 2" [50 Pack] White Corrugated Boxes, Ventilated, Grease-Resistant, Durable for Pizza, Catering or Shipping Use Review (2026)

Who benefits from a bulk box of pizza boxes

Karat is a foodservice packaging brand under Lollicup, and this listing is built for volume: 50 white corrugated boxes at 12 by 12 by 2 inches, sized for a standard medium pizza. That makes it a fit for home cooks who bake pizza often enough to want takeout-style packaging on hand, small catering setups, pop-up food stalls, or anyone throwing a pizza party who wants each guest to get their own labeled box. It is overkill for a household that bakes pizza once in a while, since 50 boxes is a lot to store flat and work through. The boxes are also described as usable for general shipping or mailing beyond pizza, which adds some flexibility for a small business that ships flat items like apparel, books or prints and does not want to keep two separate box types on a shelf.

What the corrugated build and ventilation do

The boxes use thick B-flute corrugated cardboard, the same fluted-paper construction used in shipping boxes, which gives them more crush resistance than a thin single-wall pizza box. Karat built in grease resistance, so oil from cheese and toppings is less likely to soak through and weaken the box during the trip from oven to table. Four ventilation holes in the design let steam escape from a hot pizza, which matters because trapped steam is what makes a pizza crust turn soft and soggy inside a closed box. Together, the corrugated strength and the vents are aimed at keeping a fresh-baked pizza's crust closer to how it came out of the oven, rather than steaming itself over a short trip across a room or a few blocks for delivery.

Using them for pizza night or beyond

Every box in this pack ships flat and needs folding into shape before use, which takes a few seconds each but adds up if you are setting up dozens at once for a party. Once assembled, the white finish keeps them plain enough to write on, stamp, or stick a label on for a bake sale or pop-up stand. Because Karat markets them as convertible to a shipping or mailing box, the same stock can double as packaging for small flat items when it is not pizza season, which is a useful way to avoid wasted inventory for a small business. For a home kitchen, the simplest use is stacking a handful assembled near the oven on pizza night so guests can box up their own slices to take home without dishes.

What to weigh before buying 50 at once

The obvious trade-off against rivals in this guide, like the 100-pack PerKoop boxes or the smaller 20 and 25 count packs from BOARDS+ and PETIT MANON, is quantity. Fifty boxes is a middle ground: more than a casual party needs but fewer than a business ordering in bulk, so it is worth checking your actual usage before committing to a pack this size. White corrugated stock also costs a bit more than plain brown kraft alternatives like the G.C.C. Converting boxes, though it looks cleaner for a party table or a gift box. None of these boxes come pre-folded, so if a fully assembled, ready-to-fill box matters more to you than price, factor in the extra setup time across all 50 before an event rather than discovering it the night of the party.

Bottom line on the Karat 50 pack

For anyone who bakes or serves pizza regularly enough to want dedicated packaging, this 50 pack of Karat white corrugated boxes delivers a grease-resistant, ventilated design at a size that fits a standard medium pizza, with the bonus of doubling as general shipping boxes. It is a strong pick for small food businesses, frequent pizza-night hosts, or anyone planning a group pizza party who wants to send guests home with leftovers in a real box rather than foil. Skip it if you only bake pizza occasionally, since 50 flat boxes need a dry storage spot and will sit unused for a long time, or if you specifically want boxes that arrive pre-assembled rather than flat-packed. In those cases, a smaller count pack from elsewhere in this guide is the more practical starting point.
