In 1928 in St. Paul, Minnesota, Richard Drew invented Scotch tape. Tape can be divided into: high temperature tape, double-sided tape, insulating tape, special tape, pressure-sensitive tape, 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. 1928 Scotch tape Richard Drew, St. Paul, Minnesota, USA Filed in the UK and USA on May 30, 1928, Drew developed a very light, one-press adhesive, an initial attempt Not sticky enough, so 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 have found hundreds of uses for the tape, ranging from mending clothes to protecting broken eggs. Adhesive tape is composed of two parts: substrate and adhesive, which connect two or more disjoint objects together 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 own 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, different types, there are various polymers. According to the base material: it 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.
According to the market penetration rate: it can be divided into ordinary tape and special tape.
According to the application environment temperature: it 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.
Specification
(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. one-sided
The tape can be used for packaging or temporary fixing of objects. It can be easily torn without any tools. There is no glue residue on the adhered surface after tearing off. It is a single-sided tape with embossed PVC as the base material, which is easy to tear without and leaves no glue residue. The new product S8855B has been developed. In function, it can partially replace the existing waterproof cloth-based single-sided tape S9522R or 4701, and the price is more competitive. The tape has been tested in the Beijing East Road store. The color is earth brown in the early stage, and it can be cut and produced according to customer specifications. Heat sealing tape is heated by special equipment (hot air seam sealing machine or high-frequency heat sealing machine), and sewed on the knitted bone pinholes of waterproof and air-proof series products such as raincoats, tents, air balloons, etc., to achieve sealing (water leakage prevention). , anti-leakage) effect of a tape.
As we all know, there will be pinholes in the processing and production of clothing, and of course the waterproof series is no exception. How to ensure that these needles are not leaking, such a seemingly simple problem has puzzled us for thousands of years, because ordinary tape does not stick to water.
In the 20th century, it was used by only a few countries in the world, and the material was very expensive. It only appeared in countries with relatively developed military industries such as the United States and the Soviet Union, and it was only used in aerospace technology. The technology is kept secret from other countries.
