Advantages

Constructed from high-performance polyester material, these self-adhesive printer labels offer exceptional resistance to harsh environmental conditions, including abrasion, extreme temperatures, weathering, and exposure to fuels, oils, and solvents. The permanent acrylic adhesive ensures a secure bond on smooth, rough, and powder-coated flat surfaces. Additionally, the halogen-free construction provides enhanced safety for various industrial, commercial, and office applications while maintaining compliance with recognized industry certifications.

Suitable for

• Labelling industrial equipment and machinery components
• Identifying circuit boards and electronic panel parts
• Creating durable barcodes for asset tracking
• Organizing cables, wires, and workspace inventory

These labels may not be suitable for temporary marking tasks where clean, residue-free removal is required, as the permanent adhesive is engineered for long-term bonding. They are also not designed for application on highly flexible or continuously bending soft-plastic surfaces where rigid polyester material might lift.
