For which application might it be preferable to use long rolls of construction-grade polyethylene film instead of salvage covers?

Using long rolls of construction-grade polyethylene film is particularly beneficial when covering a long retail display counter. This type of film is designed for large area coverage and provides a waterproof barrier, which is essential for protecting merchandise from water damage during firefighting operations or when dealing with overhead suppression systems.

When covering items with a significant length, such as a display counter, the seamless nature of the roll allows for easy application without requiring multiple smaller covers that may leave gaps. This prevents any potential exposure of the items to smoke, water, or other contaminants that can occur during fire suppression efforts or when managing water run-off.

In scenarios involving furniture in the middle of a room or a twenty-gallon fish tank, smaller covers might suffice and may be more practical for those specific needs. A vertical surface can also be covered effectively with smaller or more specialized options. Therefore, the choice of long rolls is optimal for larger, continuous surfaces such as a retail display counter where a comprehensive protective solution is needed.
