Walls built using big bags instead of smaller traditionally used sandbags were termed the big bag wall, or big bag barrier. In North America, FIBCs are often used in flood prevention as well. An 1850 kg bag (4,070 lbs) has a foot print of at least 3 feet by 3 feet, and a height of almost 4 feet – building a solid wall of sand, 400 regular ...
A standard flexible intermediate bulk container can hold 500 to 1,000 kg (1,100 to 2,200 lb) and manufacturers offer bags with a volume of 285–2,830 litres (10–100 cu ft). [2] Flexible intermediate bulk containers are made of woven polyethylene or polypropylene or other heavy polymers.

Unit loads can be used both for in-process handling and for distribution (receiving, storing, and shipping). Unit load design involves determining the type, size, weight, and configuration of the load; the equipment and method used to handle the load; and the methods of forming (or building) and breaking down the load.
Specific surface area (SSA) is a property of solids defined as the total surface area (SA) of a material per unit mass, [1] (with units of m 2 /kg or m 2 /g). Alternatively, it may be defined as SA per solid or bulk volume [ 2 ] [ 3 ] (units of m 2 /m 3 or m −1 ).
