b. Minimum floor area coverage（%）

Minimum floor area coverage（%）: The minimum acceptable ratio of the cargo base area per layer to the pallet base area for the user..

When a layer's coverage reaches the minimum, that layer is considered a fully covered layer (equal to the pallet base area), and the software adopts the placement combination.

In the example below, the user sets the Minimum floor area coverage to 82%.

1) The bottom green cargo's placement combination reaches the 82% coverage requirement, so it is adopted.

2) The middle gray cargo's placement combination also reaches the 82% coverage requirement, so it is adopted.

3) But when the upper (gray) layer's coverage is higher than the lower (green) layer's coverage, the upper layer can have overhang.

4) Although there are gaps and overhangs at corners, in real operations they can be avoided by spreading cargo and adding cushioning to prevent upper-layer overhang.
