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, 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. The tape can be used for packaging or temporary fixing of objects. It can be easily torn without any tools. There is no 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 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.
