Problems solved by technology

[0002] In production and life, people have developed many identification products such as paper labels, metal signs, and heat-shrinkable identification tubes to identify cables. Although they have their own characteristics, they cannot fully meet the needs of special occasions and harsh conditions. At the same time, with the development of social economy, people's awareness of safety and environmental protection is getting stronger and stronger, and it is necessary to provide a better environmentally friendly, safe and practical marking product
