Some Popular Science Knowledge about Sealing Tape

2021-03-19

There were many newly-invented adhesive products in the 20th century. And the most eye-catching things of it was Sealing Tape, which was invented by Richard Drew in 1925.
There are three key layers in the sealing tape invented by Lu. The middle layer is cellophane, a plastic made of wood pulp, which gives the tape mechanical strength and transparency. The bottom layer of the tape is the adhesive layer, and the top layer is the most important. It is a layer of non-sticky material. Most substances have a very low surface tension when in contact with it and cannot easily wet it (so we will use it to make non-stick pans). Applying it to the tape is really a wonderful way, which means that the tape can be attached to itself, but it will not stick to each other permanently, so that it can be made into tape rolls.
For people who are not good at tearing tape, they should like to use electrical tape, which can be torn apart without scissors. Because the fabric fibers run through the entire roll of tape for reinforcement, it makes it easier to tear. At the same time, electrical tape is also a daily necessity for electricians.

The strength of the tape comes from the fabric fiber, and the adhesiveness and flexibility come from the plastic and the adhesive layer.
