SATO SR15LT-51168 4x6 Polypropylene Thermal Label
The SATO SR15LT-51168 is a 4" x 6" polypropylene thermal transfer label engineered for industrial and enterprise labeling operations requiring durability and reliability. Each case contains 4 rolls of 300 labels (1,200 total) wound on 1.5" inner diameter cores with 4.375" outer diameter, designed for seamless compatibility with SATO industrial thermal transfer printers. The polypropylene facestock combined with permanent acrylic adhesive delivers superior performance in moisture-heavy and high-wear environments where standard paper labels fail.

Industrial Applications
The SR15LT-51168 is ideal for warehouse inventory management, manufacturing asset tracking, distribution center operations, food packaging, retail labeling, and cold storage environments. The moisture-resistant synthetic construction makes it suitable for exposed environments, curved or textured surfaces, and applications requiring extended label lifespan. Common uses include inventory barcodes, shipping and logistics labels, product identification, and compliance labeling in industrial settings.

Polypropylene labels represent a step up from coated paper stock, offering genuine advantages in specific use cases. The permanent acrylic adhesive is engineered to bond reliably to non-ideal surfaces—textured plastics, curve-molded containers, and even condensation-prone environments. Unlike removable adhesives, permanent formulations won't peel under stress or humidity cycling.
The thermal transfer printing method ensures crisp barcode and text rendering essential for scanning accuracy in warehouse automation. Organizations should verify ribbon compatibility (the SR15LT-51168 works with wax, wax-resin, and resin formulations) and test edge cases like extreme temperatures before full deployment. For high-volume operations, bulk case ordering reduces per-label costs significantly.
This product fills a practical gap between budget paper stock and premium synthetic materials, making it a solid choice for mid-tier durability requirements in logistics and manufacturing.
