The specifications of jumbo tape rolls are typically expressed as "width × length × thickness." "Width" refers to the width of the tape, usually measured in millimeters or centimeters; common widths include 60 mm, 48 mm, 45 mm, 40 mm, and 30 mm.
"Length" refers to the total length of the tape when unrolled, usually measured in meters or yards; common lengths include 50 m, 100 m, 150 m, 200 m, and 500 m. "Thickness" refers to the combined thickness of the BOPP base film and the adhesive layer, usually measured in microns, with a common range of 45 to 55 microns. An example specification would be "50 mm × 100 m × 50 microns."
Currently, there is no comprehensive national standard for the tape industry; instead, the industry primarily follows the standard "QB/T 2422-1998: BOPP Pressure-Sensitive Adhesive Tape for Sealing."
In the tape industry, the price of jumbo tape rolls is typically calculated based on the rate per square meter; the price for an individual roll is determined by multiplying the width by the length and then by the price per square meter.
