A bulk box, also known as a bulk bin, skid box, pallet box, bin box, gaylord, or octabin, is a pallet-size box used for storage and shipping of bulk or packaged goods.[1] Bulk boxes can be designed to hold many different types of items such as plastic pellets, watermelons, electronic components, and even liquids; some bulk boxes are stackable.
In the U.S. and Canada, the term gaylord is sometimes used for triplewall corrugated pallet boxes; this is due to the first bulk bins being manufactured by the original Gaylord Container Company of St. Louis,[2] which was acquired by Crown Zellerbach of San Francisco in 1955.[3][4]
Construction
Bulk boxes are often made of corrugated fiberboard, either doublewall or triplewall. Many corrugated bulk boxes have covers.[2] The main body of some is similar to a half slotted container with flaps on the bottom; others have a separate base (similar to the cover) and a sleeve for side walls. Additional corrugated liners and box reinforcement are sometimes used to control bulging.[5][6]
Wooden boxes are also used for bulk packaging; boxes made of aluminum and steel are common in heavy industry. Reusable plastic totes (molded or corrugated plastic) are used for some products and logistics chains.
For some products, inner plastic liners or bin bags are used to protect the contents. Sealed inner bags with integral valves are sometimes used for liquids. Most bulk boxes are recyclable, returnable, or reusable. Some styles of boxes fold (knock down) or come apart for easier return shipments.

Bulk boxes are used for loose parts, mixed small containers, granular materials, powders, liquids, etc. Use in industry is common: shipping and storage of bulk intermediate materials prior to further processing or packaging. They are sometimes used to collect and ship materials for recycling and waste.
When used to ship hazardous waste or dangerous goods, box construction and use are highly regulated.
