Individual mills may use different methods of calculating M-Weight so results are estimates only.
Certain products (particularly higher-caliper SBS and recycled board) can vary in basis weight and therefore, M-weight.
Moreover, actual selling M-weight may be calculated on the full width of the roll (i.e., size + waste), thereby increasing the M-weight.
Call your sales representative to confirm M-weight.
