Why Thermal? Thermal Transfer Jewelry Tags are the most durable tags available on the market. Stuller’s jewelry tags are guaranteed to perform when it comes down to harsh ultrasonic and steam cleaning processes, hot display lighting and skin acids. They are also preferred for security purposes because of their tear-resistant polyester. Other advantages of thermal transfer printed jewelry tags include: Professional looking displays, better durability than handwritten tags, and faster application. Our standard solid 2 mil thick glass polyester material with an aggressive permanent adhesive is the most used in the industry. The label tails or shanks are free of adhesive. When printed with our resin ribbon it becomes a very durable, scratch resistant tag that easily survives many cleaning processes. Our signature transparent (clear-shank) material features heavy-duty 3 mil glass polyester for a tear-resistant tag. It uses an aggressive, permanent adhesive except in the unique clear shank or tail zones. When printed with our resin ribbon it creates a very durable, scratch resistant tag that easily survives many cleaning processes.
