When was sellotape made

At the time, 3M only made sandpaper. The brand Scotch came about while Richard Drew was testing his first masking tape to determine how much adhesive he needed to add. The troops needed a waterproof tape that could seal considers and repair equipment. The cloth tape was coated with Polyethylene and Duct Tape was born. The full understanding of adhesion and adhesive tapes continued to evolve and will only lead to new adhesive tape in the future. Today, there are too many adhesive formulations and applications to name, but we provide a pretty darn good list of tapes here.

It is interesting that our discovery and adhesive tape history all started with tree sap! Here is a well made video from the Science Channel to help you understand how tape is made. Adhesive Tape Consultant. Tape Tape History. In , Soviet scientists showed that triboluminescence caused by peeling a roll of an unidentified Scotch brand tape in a vacuum can produce X-rays.

In , American scientists performed an experiment that showed the rays can be strong enough to leave an X-ray image of a finger on photographic paper.

Once the acetate film is produced, it is wound on large spools and loaded into a machine that applies the adhesive.

This drawing shows the makeup of a layer of cellophane tape. The release coating makes the tape easier to unwind, while the primer helps secure the adhesive to the film. Periodicals Axinn, David.

He developed a policy known as the 15 percent rule, which allows engineers to spend 15 percent of their work hours on passion projects. Give people the room they need. The 15 percent rule has deeply influenced Silicon Valley culture—Google and Hewlett Packard are among the companies that give their employees free time to experiment.

The Scotch tape story is now a classic business school lesson, a parable of the value of instinct and serendipity, which Drew once called , "the gift of finding something valuable in something not even sought out.

After his tape successes, Drew was tapped to lead a Products Fabrication Laboratory for 3M, where he was given free rein to develop new ideas. He and his team would file 30 patents, for inventions from face masks to reflective sheeting for road signs. He would also become known as a great mentor, someone who helped young engineers hone their instincts and develop their ideas.

Drew retired from 3M in and died in , at the age of In , he was posthumously inducted into the National Inventors Hall of Fame.
