Technical Field
[0001] This utility model relates to the field of tape technology, and in particular to a waterproof PFA film tape. Background Technology
[0002] Adhesive tape consists of a support ring, a tape body wound around the support ring, and an adhesive layer coated on the inner surface of the tape body. The outermost layer of the tape body has a tape break. During use, two or more unconnected objects are joined together through the adhesive layer. Due to its convenience, practicality, and low price, adhesive tape is widely used in various fields of daily life and production. Depending on its application, adhesive tape can be classified into heat-sealing tape, butyl tape, transparent tape, insulating tape, anti-corrosion tape, shielding tape, Mara tape, metal sheet composite tape, foam tape, floor tape, etc. Currently, during use, it is necessary to first locate the tape break on the outermost layer of the tape body, as the tape break and... The lower layers of tape are of similar or identical color, making them difficult to identify. This results in a longer time spent searching for tape breaks, reducing the ease of use of the tape and affecting work efficiency. For example, China has disclosed "a kind of tape" with the application number "CN202123010888.1". It adds a color-changing coating to the release film of the tape. When the tape is accidentally exposed to ultraviolet light and fails prematurely, the color-changing coating on the release film will change color simultaneously, serving as a warning and identification function. However, it cannot ensure the overall waterproofness of the tape and prevent water penetration and damage. It cannot be directly removed for the next use and cannot avoid the trouble of finding and dealing with tape ends, thus failing to improve work efficiency. Utility Model Content

Through the cooperation of a tough layer, a flame-retardant layer and a waterproof coating, the tough layer provides good flexibility and impact resistance, which helps the tape maintain stability in changing temperature and humid environments. The waterproof coating ensures the overall waterproofness of the tape, preventing water penetration and damage. The flame-retardant layer can effectively reduce the spread of flames and enhance safety. Through the cooperation of the groove, slider, connecting rod and fixing plate, the open end of the tape can be stuck to the fixing plate after each use, so that it can be directly removed for the next use, avoiding the trouble of finding and disposing of the tape end and improving work efficiency.
