Standard input-output norms govern permitted raw-material proportions for BOPP film exports, specifying allowed inputs by product type.

Standard Input-Output Norms set permitted constituent materials and their proportions for three BOPP film export products. Each product specifies which input items are allowed: MTG permits items 1, 2, 3, 4 and 5; Matte permits items 1, 2, 3 and 5 with a fixed allowance for item 5; Thermo Lamination permits items 1, 2, 3, 4 and 6.
