PVC labels are widely used in the medical industry due to their ability to withstand rigorous sterilization cycles. This article will focus on how PVC labels are designed to endure high temperatures and harsh sterilization chemicals, such as ethylene oxide (EtO) gas, for up to 100 cycles without peeling or fading. In particular, low-temperature adhesives are selected for these labels to maintain their integrity under extreme conditions. By understanding the unique properties of PVC labels, healthcare professionals can ensure long-term labeling reliability, improving the traceability and safety of medical instruments. We will also discuss the key characteristics that make PVC labels suitable for medical applications, and how they contribute to the durability of medical devices.
