Coffee Break Training: Storage Practices: High-Piled Storage: Banding or Encapsulating? [open pdf - 220KB]
"This stack of palletized products awaits loading into the nearby rack storage system. Each pallet of material is known as a 'unit load.' Notice how the unit loads are wrapped with a thin plastic sheet. This sheet stabilizes the load and prevents small items from slipping off. However, the arrangement creates a potential problem that the fire inspector may need to address. If a unit load of combustible commodities is wrapped with a plastic sheet completely enclosing the sides and top (all five faces) it is classified as encapsulated. On the other hand, if it is wrapped only on four sides, it is said to be banded."
