Description
457 × 457 × 305 mm Heavy Duty Double Wall Cardboard Box (18×18×12″)
Our 457 × 457 × 305 mm double wall cardboard box — also known as an 18×18×12 inch heavy‑duty carton — is engineered for strength, durability and reliable protection of larger or heavier items during transport or storage.
Manufactured from double layers of fluted corrugated cardboard (BC Flute ~7 mm thickness), these boxes offer significantly greater crush resistance compared to single wall cartons. That makes them ideal for items that are heavy, bulky or fragile, and for applications ranging from warehouse dispatch to removals and export packing.
