A-Loads

A-loads are the most common load seen today. These loads consist of uniform boxes that are the same dimensions and weights. They have uniform edges, both vertically and horizontally and have no protruding edges. This limits the risk of the palleted boxes tearing or puncturing the film as it’s applied. The load’s uniformity is consistent with the pallet it’s stacked on. A proper A-load will have a footprint that almost matches the pallet deck exactly.

B-Loads

B-loads are not quite as uniform as their class A counterpart. These loads don’t have the consistent edge profiles of an A-load, but still hold some uniformity in shape. B-loads are built with inconsistent boxes and may result in some minor edges that can catch, or snare stretch film as it is applied. B-loads will also often feature load footprints that doesn’t match the pallet deck.

C-Loads

C-loads are loads that have the highest risk of causing tears and punctures during the wrapping process. C-loads are unique. No C-load will have the same edge profile as another. These unique and uneven edges make C-loads the most likely load to cause stretch film tearing or puncturing. A uniform load may also be marked as a C-load if it is very heavy, light or has poor weight distribution making it unstable. These loads are difficult to handle and often require special equipment to wrap without causing a pallet collapse.
