- Medical Industry:
Epoxy labels are widely used in the medical field for sterilization monitoring and identification. Many medical devices and pharmaceutical packages require ethylene oxide (EtO) sterilization, and epoxy indicator labels visually confirm whether items have been effectively sterilized. For instance, hospital Central Sterile Supply Departments (CSSD) often apply epoxy labels to instrument packs, where a color change—such as from red to blue—indicates successful sterilization. Pharmaceutical companies also use epoxy labels during the sterilization process of packaging to ensure aseptic conditions, while meeting regulatory requirements for traceability and verifiability of medical device sterilization. - Electronics and Electrical Industry:
In this industry, epoxy labels are commonly used for component identification and protection. Epoxy resin’s excellent electrical insulation properties make it ideal for insulating labels on components like rectifiers and transformers, protecting against electrical interference and short circuits. For electronics operating in harsh environments—such as outdoor telecom stations or industrial control systems—epoxy labels offer resistance to high temperatures, humidity, and chemical corrosion. They maintain legible information over time, aiding maintenance and management. Additionally, epoxy labels are used for part traceability and quality control throughout the electronics manufacturing process.
- Automotive Industry:
Epoxy labels play a critical role at various stages of automobile manufacturing. In component production, such as for engines and transmissions, they are used to mark model numbers, specifications, and production batches—facilitating traceability and inventory control. During vehicle assembly, epoxy labels are applied in high-temperature or oil-exposed areas—such as under-hood wiring and piping—where they provide strong adhesion and wear resistance, even in challenging conditions. As vehicles become increasingly intelligent, epoxy labels are also used to identify and protect electronic control units (ECUs), ensuring reliable operation in complex electrical environments. - Chemical Industry:
Due to their excellent chemical resistance, epoxy labels are ideal for marking corrosive or hazardous chemicals. They are commonly used on chemical drums and reagent bottles, displaying information such as chemical name, composition, hazard level, and handling instructions. This ensures clear safety warnings and operational guidance for users, helping to prevent accidents and misuse. - Handicrafts and Accessories Industry:
In the production of hardware accessories and decorative crafts, epoxy labels are often used for nameplates and branding. Epoxy resin can be processed to create labels with a glossy, three-dimensional appearance—enhancing the aesthetic and perceived value of products. High-end jewelry, commemorative coins, trophies, and similar items often feature epoxy labels to indicate brand, material, or specifications, while also serving as a form of anti-counterfeiting.
- Aerospace Industry:
The aerospace sector demands extremely high performance from materials. Epoxy labels, known for their resistance to heat, corrosion, and mechanical stress, are used in both component manufacturing and assembly. They help identify part numbers, production dates, and inspection data—ensuring traceability and quality assurance. In avionics, epoxy labels are also used for insulation and protection, supporting equipment reliability in the complex environments of high-altitude flight. - Food and Beverage Industry:
In this industry, epoxy labels are mainly used for packaging identification. Their water- and oil-resistant properties ensure that labels remain intact and legible throughout food processing, storage, and sales. Labels typically display product names, ingredient lists, production dates, shelf life, and nutritional information—supporting consumer transparency and food safety compliance. For refrigerated or frozen foods, epoxy labels maintain strong adhesion even in low-temperature conditions, preventing peeling.
