Multilayered adhesive tapes known as Seam Sealing Tapes are applied to sewn seams to keep air and moisture out. The multilayered tapes used for seam sealing are constructed from paper, fabric, foam, plastic film, and foil and are covered in adhesive. They are thermally activated and applied using a hot air taping machine. The tapes are used in a variety of products, including military clothing, tents, waders, footwear, and outerwear.
Seam Sealing Tapes are run through a hot air taping machine and have numerous uses in the industrial sectors for shoes, tents, clothing for the workplace, waders, and uniforms for the military. In order to stop moisture infiltration and strengthen the seam joints, seam sealing tape is an adhesive tape that is applied to the seams of clothing and other manufactured goods. Seams are sealed with multi-layered tapes comprised of aluminium foil, fabric, plastic film, and adhesive-coated sheets. In addition to waterproofing, seam sealing tapes also provide additional strength and durability to seams. Seams that are not sealed are more likely to fray and tear over time, especially in high-stress areas such as elbows and knees. Seam sealing tapes help to reinforce these areas and prevent them from becoming weak points. The application technique for Seam Sealing Tapes varies depending on the type of tape and the material being sealed. The most common application techniques include: Hot air sealing is the most common technique for applying hot-melt seam sealing tapes. The tape is placed over the seam, and a hot air sealing machine is used to melt the tape and fuse it to the fabric. Hot air sealing is a quick and efficient method that produces durable and long-lasting seams. Pressure-sensitive Seam Sealing Tapes can be applied using pressure alone. The tape is placed over the seam, and pressure is applied using a roller or a press. The pressure-sensitive adhesive forms a bond with the fabric, creating a watertight seal. Weldable Seam Sealing Tapes can be applied using radio frequency (RF) or ultrasonic welding techniques. RF welding uses electromagnetic waves to generate heat that melts the tape and fuses it to the fabric. Ultrasonic welding uses high-frequency vibrations to create heat that melts the tape and fuses it to the fabric. Both techniques produce highly durable and long-lasting seams.
