It is made of breathable non-woven fabric and spunlace fabric as the base material, coated with natural rubber and medical pressure-sensitive adhesive. It can firmly adhere to the skin while ensuring air circulation and sweat wicking, reducing allergies and discomfort caused by stuffiness and humidity. It has good skin affinity and low sensitization rate, and is widely used in wound dressing, plaster fixation and electrode pad bonding, providing people with a convenient and comfortable care experience.

[0003] Early adhesive application was mainly done manually. Workers used simple tools and relied on experience to apply glue to the surface of breathable adhesive tape. Although flexible, this method was inefficient, and it was difficult to guarantee the uniformity and consistency of the glue application, resulting in inconsistent product quality. With the advancement of industrial technology, various adhesive application equipment has emerged, greatly improving the flexibility and adaptability of adhesive application. However, existing breathable adhesive tape application devices still have many problems. The adhesive tape is prone to wrinkling during the application process, resulting in low application precision. This not only affects the appearance quality of the breathable adhesive tape but also makes it difficult to meet the core indicators of breathability and adhesion. Utility Model Content
