Page Flags & Tabs vs. Tape Core Diameters
Comparing 2 standards across 12 specifications. 12 key differences identified.
Page Marker Flags (repositionable film index tabs and arrow indicators) are thin polyethylene terephthalate (PET) film strips measuring 0.5 inches (12 mm) or 1.0 inch (25.4 mm) in width by 1.75 inches (44 mm) in length. Featuring a translucent adhesive body and brightly colored tip, they flag contract signature lines ('Sign Here') and textbook pages without obscuring text.
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.
