The specification of BOPP sealing tape is expressed as "width x length x thickness", where "width" refers to the width of the tape, usually expressed in mm or cm, generally ≥ 10mm. Before the 1980s, common specifications included 72mm, 60mm, 50mm, 30mm, etc; Nowadays, it has gradually been changed to 60mm, 48mm, 45mm, 40mm, 30mm, etc; The "length" refers to the total length of the tape after it is pulled open, usually expressed in "m" or "code" (1 code=0.9144m). Common lengths include 50m, 100m, 150m, 200m, 500m, etc; Thickness refers to the total thickness of BOPP film and adhesive layer (unit: micrometers, μ m), commonly ranging from 45 to 55 μ m. Such as "50mm × 100m × 50 μ m".
The calculation method for the unit price of each roll of tape: The tape industry usually uses "yuan/square meter" to calculate the price of tape, so "the price of each roll of tape=width (m) * length (m) * square price".
