Custom Printed Pizza Box Liners Cut to Your Box Size

What does a pizza box liner do?

A pizza leaves the oven full of moisture. In a closed box, that moisture turns to steam and settles on the base, and the crust starts to soften.

A liner sits between the pizza and the floor of the box. A fluted liner raises the crust on narrow ridges. Steam and oil then gather in the channels below, away from the dough.

A greaseproof liner works differently. It does not lift the pizza, but it stops oil from soaking through to the box floor.

Fluted pad or greaseproof sheet?

Both have a place. The choice depends on how long the pizza travels and what matters most to you, the crust or the box.

Who uses liners in their pizza boxes?

Delivery pizzerias are the main users. When a pizza spends fifteen to thirty minutes in a bag, a fluted liner makes a clear difference to the crust.

Shops selling deep-pan or extra-cheese pizzas also use liners. Those pizzas shed the most oil, and it is the oil that stains the outside of the box.

Some businesses use liners for reasons beyond the crust. A liner lets a shop use a plain, lighter box while still keeping grease off the board.

Caterers carrying a stack of pizzas to an office or party also find them useful. Pizzas at the bottom of a stack are the first to steam.

• Delivery-led pizza takeaways with longer drive times
• Pizzerias selling deep-pan, stuffed-crust or extra-cheese bases
• Market traders reheating slices in a hot box
• Frozen and take-and-bake pizza sellers protecting the box floor

How do you size a pizza box liner?

Measure the inside floor of your pizza box, not the outside. Then take off about 5 mm from each side so the liner drops in flat without buckling.

A liner that is too big curls up at the walls and pushes the pizza off-centre. One that is too small leaves an oil-catching gap at the edges.

Round liners are cut to the pizza diameter instead. They suit shops that want the liner hidden under the crust.

Our guide to pizza box sizes in inches shows how box and pizza sizes relate.

Which way up does a fluted liner go?

Ridges up. The pizza should rest on the tops of the flutes, with the channels running underneath.

If the smooth face is up, the liner simply acts as a thicker floor. It still protects the box but does far less for the crust.

Our fluted pads are white or kraft on the fluted side. White looks cleaner when the box is opened, while kraft matches a kraft box.

The flutes are easy to feel with a fingertip, so staff can check the side by touch even when rushing.

Can pizza box liners be printed?

Yes, though it depends on the type. Greaseproof liners take print well, from a simple one-colour logo to a full colour CMYK pattern.

Fluted pads have a ridged surface, so fine detail does not print sharply on them. A bold one-colour logo on the flat back is the usual choice.

Printing the liner is an easy way to brand a plain box. Many shops keep stock boxes plain and let a printed sheet carry the logo inside.

How do you use liners on a busy line?

Pre-loading liners when you fold boxes before service means nobody has to think about them during the rush.

Store liners flat and dry. Fluted pads crush if heavy items sit on top of them.

1. Keep a stack of liners beside the box pile, cut to that box size.
2. Drop a liner into each box as it is folded, ridges up.
3. Slide the pizza on from the peel so it sits in the centre.
4. Close the lid and send it out as normal.

What are the common mistakes with liners?

The most common one is buying a single liner size for several box sizes. Small boxes then end up with liners folded at the edge.

Another is laying fluted liners upside down, which wastes the whole point of the ridges.

Some shops also expect a greaseproof sheet to keep the crust crisp. It protects the box, but only a raised pad really helps the base.

Do liners work with every pizza box style?

They work with square, octagonal and round pizza boxes, as long as the liner is cut to match the floor. For octagonal boxes, a round or cut-corner liner fits best.

Slice boxes and long garlic bread boxes can take liners too. These are usually greaseproof, since a fluted pad adds height a small box cannot spare.

If you also need the boxes, see our white pizza boxes for clean branding, which pair well with white liners.

Is a liner cheaper than upgrading the box?

Often it is. A liner adds a small cost per pizza. Moving every box from E flute to B flute raises the cost of the whole carton.

Liners are also flexible. You can use them only on the sizes or pizzas that need them, such as deep-pan bases or late-night delivery runs.

Some shops test this by sending a batch out with liners and a batch without. Ask drivers and customers which crust arrived crisper, then decide.

If oil marks on the outside are your main worry, a grease-resistant coating on the box may be enough. If soft bases are the problem, the ridged pad is the better spend.
