The historical source of adhesive tape, how to distinguish the quality of tapes from the history of tape 1928 Scotch Tape the United States of America, Minnesota, May 30, 1928, in the UK and the United States filed applications, drew developed a lightweight, pressure-bonded binder that was initially not sticky enough to be told: "Get this thing back to your Scottish bosses and ask them to put some more gum on!"
