Heat Sealing Tape
Mar 14, 2018


The heat sealing tape is heated by special equipment (hot air seam sealing machine or high frequency heat sealing machine) and sewed in the knitted bone position pinholes of waterproof, airproof products such as raincoats, tents, and air balloons to achieve sealing (water leakage prevention , anti-leakage) effect of a tape.


It is well known that garments will have pinholes in the production process. Of course, the waterproof series is no exception. How to ensure that these needles do not leak water, this seemingly simple problem also puzzled us for thousands of years, because the ordinary tape does not have the power to meet the water.


In the 20th century, only a handful of countries in the world used them. The materials are very expensive. They have only emerged in the developed countries such as the United States and the Soviet Union, and they are only used in space science and technology. It is even more technically confidential in other countries.
