Adhesive Options for Direct Thermal Labels

Direct thermal labels are a type of label that uses heat-sensitive paper to create images without the need for ink, toner, or ribbons. When exposed to a thermal printhead, the paper changes color, typically turning black where the heat is applied. This makes direct thermal labels a cost-effective and efficient option for short-term applications. However, because they are susceptible to fading and environmental damage, especially in high-heat or UV-exposed areas, they are best suited for applications where the label’s lifespan is relatively short.

Typical Applications and Industries

• Logistics and Shipping: Direct thermal labels are widely used for shipping labels and logistics, where quick, clear printing is essential, but the labels only need to last for a short duration during transit.
• Retail: Retail environments use direct thermal labels for price tags, product labeling, and barcodes, taking advantage of the technology’s efficiency and ease of use.
• Healthcare: Direct thermal labels are used in healthcare for patient records, specimen tracking, and other applications where temporary but accurate labeling is required.
• Food and Beverage: The food and beverage industry often uses direct thermal labels for perishable goods, such as deli items and grab’n go prepared foods, where labeling needs to be quick and effective, but the product’s shelf life is limited.

• Wet Environments: When faced with challenges like moisture and water exposure, adhesives that are water-resistant and waterproof adhesives are recommended. These adhesives are particularly useful for beverage labeling and outdoor applications where moisture is a concern.
• Cold Environments: In cold environments, such as frozen food packaging or cold storage, standard adhesives may fail. Freezer-grade and cold-temperature adhesives are designed to maintain their bonding strength even in low temperatures, ensuring labels stay in place.
