White Round Cake Boards 6 to 20 Inch - 4mm Coroplast, Waterproof and Reusable

White round cake boards cut from 4mm coroplast — corrugated polypropylene, not cardboard. Sizes 6 to 20 inches, in 5, 10 and 25 packs.

The difference between this and a cardboard board

A cardboard cake board is disposable by design. Butter and oil soak through within an hour, the white face goes translucent and grey under the cake, and it shows in every photograph taken after that. Once it is used, it is rubbish.

Coroplast does not absorb anything. Wipe it down and it is ready for the next cake. The same board can carry a dozen cakes over a year instead of one, which changes the cost per use entirely.

Why it matters under a real cake

• Waterproof. Ganache, buttercream, condensation from a fridge — none of it soaks in or softens the board.
• Will not warp. Cardboard curls in humidity and after refrigeration. Coroplast holds flat.
• Rigid at 4mm. Stiff enough to lift a fully decorated cake by the board without it folding across the middle.
• Wipe clean and reuse. Warm soapy water. No solvents.
• Food-safe polypropylene. The same material used in food packaging and reusable containers.

Sizes and packs

Every inch from 6 to 20, in packs of 5, 10 and 25. A 25 pack is what working bakeries buy — the per-board cost drops and you stop reordering every month.

Boards ship flat so they arrive without creased corners. Most orders leave our Florida shop within 1–2 business days.
