Labels and hangtags are mainly used for identification and traceability of steel or other metal casting products during high-temperature production processes, requiring sustained high-temperature resistance. The main materials are PI, aluminum foil and stainless steel. The labels are made of high-quality base materials and high-temperature resistant glue specially designed for the steel industry. The maximum temperature resistance can reach 600℃, and the tags can withstand a maximum temperature of 900℃.
