Heat-sealing tape is heated by special equipment, and the heat-sealing tape is sewn on the knitted bone pinholes of waterproof and air-proof series products such as raincoats, tents, and air balloons to achieve sealing (water-leakage, air-leakage) effect. adhesive 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, only a few countries in the world used it, 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.
