How is the waterproof performance of thermal paper express label?
Publish Time: 2025-02-18
In the rapidly developing logistics industry, express labels are the key link between goods and information. Their performance and quality directly affect logistics efficiency and customer satisfaction. Among them, waterproof performance is one of the important indicators to measure the quality of express labels. Thermal paper express labels are widely used in the express industry because of their convenient printing and low cost, but their waterproof performance has always been the focus of users.The printing principle of thermal paper express label is to heat the thermal coating on the surface of thermal paper by heating the print head, so that the text and images appear. This printing method does not require carbon ribbon and ink, simplifies the printing process and increases the printing speed. However, due to the relatively fragile surface of thermal paper, its waterproof performance is relatively weak. In a humid environment, the text and images on the label are easily blurred or fall off, affecting the readability of the information and the durability of the label.In order to improve the waterproof performance of thermal paper express labels, manufacturers have adopted a variety of technical means. A common method is to apply a special waterproof coating on the surface of thermal paper. This coating can form a protective film to effectively prevent moisture from eroding the thermal coating. Another method is to improve the manufacturing process of thermal paper and use more water-resistant and moisture-resistant materials to fundamentally improve the waterproof performance of the label.In actual applications, the waterproof performance of thermal paper express labels varies depending on the brand, model and manufacturing process. Some high-end thermal paper express labels, after special treatment and optimization, can resist rain and moisture to a certain extent, ensuring that the information can still be clear and readable in bad weather. However, for some express parcels that are exposed to humid environments for a long time, such as fresh products such as seafood and fruits, ordinary thermal paper express labels may not meet their waterproof needs, and more professional waterproof label materials are needed.In addition, it is worth noting that the waterproof performance of thermal paper express labels is not static. Over time, the waterproof coating on the label may gradually age and fall off, thereby reducing its waterproof effect. Therefore, during use, users should try to avoid exposing express labels to humid environments for a long time to ensure the accuracy and durability of their information.In summary, the waterproof performance of thermal paper express labels is one of the important indicators to measure their quality. Although the waterproof performance of ordinary thermal paper express labels is relatively weak, its waterproof performance can be significantly improved by adopting special coating treatments, improving manufacturing processes, and other means to meet the needs of different application scenarios.
