Resin Ribbons: Everything You Need to Know

I. What are Resin Ribbons?

Resin ribbons are one type of thermal transfer ribbons used in thermal transfer printing. These ribbons are made from a resin-based ink formulation designed to be transferred to a substrate, typically a label or tag, using heat from the printer’s printhead. The resin ink is melted and fused onto the surface of the substrate, creating a durable and high-quality print.

Information printed with resin thermal transfer ribbons is highly durable and resistant to wear over time. These ribbons are used for the most demanding applications, such as labeling chemical containers, pharmaceuticals, engine parts, and outdoor equipment like pipes and machinery on offshore platforms.

Resin ribbons are best suited for smooth surfaces, typically synthetic materials such as PE, PP, and PET. However, they can also print on matte, synthetic, and coated paper. Some resins are even capable of printing on uncoated paper. Specialized products are available for textiles, rubber, Teslin®, and Tyvek® Brillion materials.

II. Composition And Applications of Resin Ribbon

1. Components

• Resin: Resin is the main component of the ribbon, providing high abrasion and chemical resistance. Common types of resin include phenolic resin, polyester resin, and polyurethane resin.
• Wax: Wax is an auxiliary component used primarily to adjust the ribbon’s melting point and adhesion properties. Resin-based ribbons contain a lower amount of wax to enhance their durability.
• Additives: Additives improve the performance of the ribbon, including antistatic agents, lubricants, and colorants, to enhance print quality and ribbon stability.
• Substrate: The substrate is the backing material of the ribbon, usually made of polyester film. Its role is to support the ribbon and ensure smooth transmission during printing.

2. Applications

Resin ribbons are ideal for industries where printed materials must withstand severe abrasion and exposure to chemicals, sunlight, extreme temperatures, and other harsh conditions. They are used in applications requiring long-lasting or high-impact prints that remain legible under adverse conditions.
