description 3M Post-it Notes Overview
3M Post-it Notes are paper notes with a pressure-sensitive adhesive strip that lets them be attached, removed, and repositioned for temporary use. 3M scientist Spencer Silver developed the underlying low-tack adhesive in 1968, and Art Fry later adapted it to make a bookmark that would stay in a hymnal. The product is used for reminders, annotations, sorting, and organizing work in offices, classrooms, and homes.
help 3M Post-it Notes FAQ
Why can Post-it Notes be removed and repositioned?
They use a pressure-sensitive, low-tack adhesive that holds paper to a surface without forming a permanent bond. That design lets a note be moved while leaving less residue than ordinary tape.
Who invented the adhesive used in Post-it Notes?
3M scientist Spencer Silver developed the low-tack adhesive in 1968. Art Fry later adapted it into a bookmark that could stick to and move within a hymnal.
When did 3M introduce Post-it Notes?
3M test-marketed the product in four U.S. cities in 1977 and launched it nationally in 1980. The original concept grew from Silver's 1968 adhesive and Fry's bookmark idea.
Are Post-it Notes more like paper or adhesive tape?
They are paper notes with an adhesive strip rather than rolls of tape. The strip uses 3M's removable pressure-sensitive adhesive, so the note can serve as a temporary label or reminder.
