L-T7515 is an uhf laundry tag. As uhf RFID laundry tags, L-T7515 will encounter the erosion of ultra-high pressure and chemical laundry detergent during the automatic washing process, and will be used repeatedly in a high temperature and high pressure environment, generally requiring its life of more than 200 times. This requires the RFID tag on clothes to have a very strong ability to resist pressure and fold. The most vulnerable part of the RFID tag is the connection between the antenna and the chip. In order to solve this problem, our RFID tag laundry uses coupled antenna technology, and RFID chip waterproof in the middle is small in size, which has little impact to the force. The radiation antenna has strong flexibility and is not easy to break, thus enhancing the stability of the uhf laundry tag.
