Packaging Tape
Sticky Notes

Packaging Box Sealing Tape (standardized under ASTM D5486 and PSTC-101) is a high-tensile biaxially-oriented polypropylene (BOPP) tape measuring 2.0 inches (48 mm / 1.88 in) or 3.0 inches (72 mm / 2.83 in) in width. Engineered for corrugated carton sealing, it is categorized by adhesive chemistry (Acrylic vs Hot-Melt Rubber) and mil film thickness.
