Packaging Tape vs. Tape Core Diameters
Comparing 2 standards across 12 specifications. 12 key differences identified.
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.
Adhesive Tape Core Diameters are standardized inner spool dimensions governed by PSTC (Pressure Sensitive Tape Council) and ASTM D3652. Operating on two non-interchangeable industry formats: 1.0-inch (25.4 mm) cores for compact desktop tape dispensers and 3.0-inch (76.2 mm) cores for heavy commercial desk dispensers and handheld packaging tape guns.
