The industry-standard 6" bagasse burger box The bagasse burger box in 152 x 152 x 76 mm is the format most UK operators mean when they spec a compostable burger box — the 6-inch bun-stack size that matches a standard pub burger or double smash with room for a short side of chips. The square footprint keeps the bun centred rather than sliding lengthways in a rectangular clamshell, and the 76 mm depth clears a double-patty stack without forcing the top bun into the hinge. Moulded from 100% sugarcane fibre, it replaces expanded polystyrene or coated paperboard for burger-led menus committing to a compostable line without changing the operator's bun-stack SOP. Where this format fits in the range The 6" size is the industry default; the compact 5" bagasse burger box is the paired option for sliders, single-patty pub burgers and kids' portions where 6" over-allocates. 500 boxes per case (125 per pack, 4 packs per case) — sized to high-rotation burger service. Cert docs and volume trade pricing available through the wider bagasse clamshell range.
