PSA Adhesives for Labeling

Pressure-sensitive adhesives (PSA) are essential for ensuring labels adhere reliably to a wide variety of containers, including PET, PE, PP, glass, aluminium, and metal. Modern PSA adhesives, such as polyolefin-based and rubber-based formulations, provide strong initial tack, flexibility, and clean bonding without bleeding through thin or sensitive paper labels. They also accommodate dimensional changes in containers caused by temperature or pressure variations, ensuring labels remain visually flawless and securely attached.

High-performance PSA adhesives enable high-speed production, with processing rates up to tens of thousands of units per hour. Polyolefin-based hot melts offer long thermal stability, low stringing, and reduced energy consumption, while maintaining consistent viscosity and smooth flow. These adhesives are approved for food contact applications and provide durable, flexible bonds that meet the demands of modern labeling lines.
