In 1928 in St. Paul, Minnesota, Richard Drew invented Scotch tape. Tape can be divided into the high-temperature tape, double-sided tape, insulating tape, special tape, pressure-sensitive tape, and die-cutting tape according to its function. Different functions are suitable for different industry needs. The surface of the tape is coated with a layer of adhesive to make the tape stick to the object. The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; in modern times, various polymers are widely used.
1. The principle of use of tape
Adhesive tape is composed of two parts: substrate and adhesive, which connect two or more disjoint objects by bonding. Its surface is coated with a layer of adhesive. The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; in modern times, various polymers are widely used. Adhesives can stick to things because their molecules form bonds with the molecules of the object to be connected, and this bond can firmly bind the molecules together. The composition of the adhesive, according to different brands, and different types, there are various polymers.
2. Classification of tapes
The base material: can be divided into BOPP tape, cloth tape, kraft paper tape, masking tape, fiber tape, PVC tape, PE foam tape, etc.
According to the scope of application: it can be divided into warning tape, carpet tape, electrical tape, protective film paper tape, wrapping film tape, sealing tape, module tape, etc.
The market penetration rate: can be divided into the ordinary tape and special tape.
According to the application environment temperature: can be divided into low-temperature tape, normal-temperature tape, and high-temperature tape.
According to the adhesiveness: single-sided tape and double-sided tape.
3. Specifications of tape
(1) The Jumbo Roll master roll, that is, the prototype tape on and off the machine, has a width of 1 meter to 1.5 meters, and a length of several hundred meters to several kilometers, depending on different substrates.
(2) Log Roll is the product after the rewinding of the parent roll, the width is unchanged, and the length varies according to the requirements (usually 100 meters, 50 meters, 25 meters, 10 meters, 5 meters, etc.).
(3) Slit Roll (finished roll) is a product on the general market.
