Adhesive tape

In 1928, Richard Drew invented transparent tape in St. Paul, Minnesota, USA. Adhesive tape can be divided into high-temperature tape, double-sided tape, insulation tape, special tape, pressure-sensitive tape, and die-cutting tape according to its functions. Different functions are suitable for different industry needs. A layer of adhesive is applied on the surface of the tape to make it stick to objects. Early adhesives came from animals and plants, and in the 19th century, rubber was the main component of adhesives; In modern times, various polymers are widely used.

Invention process

In 1928, Richard Drew applied for transparent tape in St. Paul, Minnesota, USA. On May 30, 1928, Drew developed a very light, one press adhesive, but the initial attempt was not sticky enough. Therefore, Drew was told, "Take this thing back to your Scottish bosses and ask them to put more glue!" ("Scotland" means "stingy"). However, during the Great Depression, people found hundreds of uses for this tape, from repairing clothes to protecting broken eggs.
