Performance Advantages

The synthetic polyester construction of the SR15LT-53181 provides superior durability compared to traditional paper labels. This material withstands exposure to chemicals, moisture, extreme temperatures, and UV radiation without fading, peeling, or degradation. The gloss white finish ensures excellent print quality and barcode readability while providing a professional appearance suitable for customer-facing applications.

When printed with SATO R333A or R435B Premier I resin ribbons, labels achieve UL Recognition status, enabling use in regulatory compliance applications such as electrical equipment identification and safety labeling. The permanent acrylic adhesive ensures labels remain securely affixed even in high-vibration manufacturing environments or outdoor conditions.

Applications

The 4" x 2" format and robust construction make these labels ideal for:

• Asset tracking and inventory management in warehouses and distribution centers
• Shipping and logistics labeling
• Manufacturing equipment identification and serialization
• Barcode labeling for supply chain operations
• UL-compliant electrical and equipment identification
• Outdoor product labeling and identification

The SR15LT-53181 represents a practical choice for operations requiring high-volume label production with superior durability. The 3,400-label case quantity reduces changeover frequency while the perforated design enables efficient single-label dispensing without scissors or additional cutting. For environments where labels face chemical exposure, temperature fluctuations, or outdoor conditions, the synthetic polyester construction eliminates common failure modes associated with paper alternatives.

UL Recognition capability through compatible ribbon selection adds compliance value for regulated industries without requiring separate label SKUs.
