Is shrink film calculated by the roll or for the product pallet? If on the pallet, what’s the best way to calculate this?

Shrink/stretch film is calculated for the product pallet to understand how much length x width of film required to wrap each pallet.

It can be measured/calculated manually, but approximate values are also acceptable. Approximate values can be decided by checking how much film is required for single wrap and multiply it by the number of wraps to be done per pallet.
