Cake Box 18″ X 18″ X 5″ / 45cm X 45cm X 12.5cm

Professional-Grade Heavy-Duty Support for Extra-Large Celebration Cakes

Say goodbye to delivery day anxiety with our Premium Extra-Large Hybrid Cake Box. Massive multi-tier cakes and wide-base celebration bakes demand industrial-strength foundation support without adding unnecessary weight on top. This specialized packaging system solves that challenge by merging a thick, heavy-duty corrugated board base with a premium, flexible soft board lid. This structural combination prevents the bottom of the box from flexing, sagging, or bowing under heavy loads while ensuring the lid remains lightweight and quick to assemble.

The expansive 45cm × 45cm square footprint provides a massive, stable arena that comfortably accommodates large custom square display boards or extra-wide round presentation bases. Boasting a generous 12.5cm vertical clearance, it offers ideal overhead safety for heavy borders, complex low-tier piping, and detailed fondant work. The pristine, unbranded matte white finish delivers a clean, high-end minimalist aesthetic that instantly matches the premium nature of your baking business—serving as an excellent canvas for your custom business stamps, logo stickers, or decorative ribbons.
