Our Step-Pak brand sleeve pack is a durable, corrugated, returnable bulk container that features a patented locking system that keeps all the components of the pack together. The pallet, sleeve and lid are kept locked together at all times, while in transit or storage, full or empty, upright or collapsed. This simple, yet very important design feature reduces loss or separation of components, as well as reducing potential damage to the pack. Our customers use the Step-Pak because it provides them a superior return-on-investment compared to competitive sleeve packs.
