In , Richard Drew joined the 3M company located in St. Paul, Minnesota. 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. Tape Glossary. PSA Tape. All pressure-sensitive tapes share two common, but deceptively simple, traits: They all have some sort of adhesive attached to a backing.
Yet to make this dynamic duo work requires as many as 30 raw materials and a bit of complex chemistry. Certain portions of distillate from crude oil are chemically reacted to form the desired raw materials.
These materials are combined in water or a hydrocarbon solvent in carefully controlled proportions and are polymerized to form the final adhesive product. As for the cellulose acetate backing, its manufacture begins with wood pulp or cotton linters.
These cellulose fibers are broken down by chemical and physical means to their basic fiber structure. A plasticizer is added to the cellulose acetate, which is then formed into sheets of film. Finally, the surface of the film is treated to give it a matte finish.
The finished film is wound up in large rolls, ready to be coated with adhesive. Once the adhesive and backing are ready, several steps are required to produce a roll of tape. First, the cellulose acetate film is surface treated. One side of the film is treated with a release coating, which makes the tape easy to unwind. The other side is treated with a primer that ensures good anchorage of the adhesive film.
A thin coating of pressure-sensitive adhesive is metered onto the film and dried. The adhesive-coated tape is wound up to form a large jumbo roll. The jumbo roll is then split into narrow bands, which are wound on individual cores to produce the retail or commercial size rolls of tape. While the tape itself worked great once it was applied, getting it off the roll wasn't easy.
The end had to be picked loose with a fingernail or other sharp instrument. Once free, the tape didn't stay that way for long. Invariably, the loose end would curl back into place on the roll, become virtually invisible, and hard to locate. Frequently, the tape tore before the desired length was cut. Even if users succeeded in getting the right amount of tape, it had to be cut off with scissors or torn haphazardly, a time-consuming and awkward task. As a result, tempers flared and complaints rolled in.
Clearly the long-term success of this new product hinged on finding a better way to mete it out. But what? John Borden, a 3M sales manager, took on the task. In , after eighteen months of experimenting, Borden developed an efficient dispenser with a built-in cutter blade. The dispenser allowed the tape to be unwound, cut, and applied in seconds.
It even kept the end of the tape free for the next application. Although there would be changes over the years—including the introduction of the iconic snail-shaped tape dispenser in —Borden's basic design has remained a standard. Borden's dispenser became a key element in the growing market for cellophane tape. This marks 3M's entry into the tape business. The first tape was a two-inch-wide tan paper strip backed with a light, pressure-sensitive adhesive.
More than different types of Scotch tapes had been developed to meet wartime requirements. The famous plaid design is introduced to Scotch tape packages. More than just transparent, the matte finish tape is virtually invisible on light-colored paper and can be written on with pen, pencil, or marker.
The exhibit features more than simple items, including Scotch tape, that are described as "masterpieces of design deserving our admiration. Paul, Minnesota. The text of the plaque commemorating the landmark reads:. Introduced during the Great Depression, Scotch Transparent Tape quickly filled the need of Americans to prolong the life of items they could not afford to replace.
These inventions have grown to a family of more than pressure-sensitive tapes used by professionals and consumers in office, medical, electrical, construction, and many other applications.

Tape, as we know it today, was invented in by a surgeon. Before tape, there was cloth and there were all kinds of adhesives, but nobody ever combined the two into what we know as tape. The key component to modern tape is that the adhesive is pressure-sensitive.
Adhesives that came before the one Dr. Day created just stuck to stuff indiscriminate of pressure. Tape has evolved tremendously since it was invented nearly years ago. The wide variety of tape one can purchase today would boggle the mind of humble old Dr.
Richard Drew of 3M invented masking tape in to help solve the problem of paint bleeding through while painting new automobiles.
