To unitise is to bring separate items together into a single unit — to make many things handle as one. In food distribution it means grouping cases, cartons, or packs onto a pallet, wrapping them as one load, so that forklifts and lorries move one unit instead of dozens of loose boxes. The verb covers the whole logic of modern logistics: standardise the unit, mechanise its movement, and track it as one entry in the system. Unitising cuts handling damage, speeds loading, and simplifies inventory — the pallet is the physical embodiment of the idea. The same principle applies in manufacturing, where ingredients are kitted as single units for production lines.
