SATO SR15LD-20123 4x4 Thermal Transfer Paper Label
The SATO SR15LD-20123 is a 4" x 4" thermal transfer paper label engineered for high-volume industrial and enterprise labeling operations. Each case contains 1,800 labels across 4 rolls (450 labels per roll), designed for seamless integration with SATO industrial thermal transfer printers. The thermal transfer paper facestock delivers excellent print quality for barcode reproduction, asset tracking, and human-readable identification across warehouse, manufacturing, logistics, and distribution environments.
Key Features
- 4" x 4" label format—versatile sizing for barcodes, asset tags, shipping labels, and product identification
- Thermal transfer paper facestock with permanent acrylic adhesive for reliable adhesion to cartons, packaging, and surfaces
- 1,800 labels per case: 4 rolls × 450 labels each
- 1.5" core ID with 4.375" outer diameter for standard SATO printer compatibility
- Perforated between labels for efficient tear-off dispensing
- Compatible with wax (T101A), wax-resin (T110A Premier II), and resin (R333A) thermal transfer ribbons
Technical Highlights
The SR15LD-20123 combines a thermal transfer paper facestock with permanent acrylic adhesive to ensure reliable adhesion across temperature ranges typical in industrial environments. The perforated design enables fast, clean label separation during dispensing, reducing operator fatigue and improving throughput. Multiple ribbon compatibility—wax, wax-resin, and resin options—allows you to balance print durability with cost, depending on label exposure and handling requirements.
The 4" x 4" format provides sufficient real estate for high-density barcodes, QR codes, and clear text while maintaining compatibility with standard printer widths. Roll configuration with 1.5" cores ensures fit across SATO's full range of industrial thermal transfer printers without adapter requirements.
Ideal Applications
- Warehouse and inventory management labeling
- Manufacturing shop-floor asset and component tracking
- Shipping and parcel identification labels
- Product labeling and batch identification
- Compliance and regulatory labeling in distribution centers

The SR15LD-20123 represents a reliable mid-tier choice for organizations running high-frequency labeling operations on SATO platforms. The 4x4 format strikes a practical balance—large enough to accommodate dense barcodes and readable text without excessive label waste or printer strain. The permanent acrylic adhesive is well-suited to industrial environments where labels face moderate handling and temperature variation; it performs consistently on corrugated, plastic, and coated surfaces without edge lift or premature failure.
The three ribbon options merit consideration: wax ribbons are cost-effective for short-term labels in controlled environments; wax-resin blends offer improved smudge and moisture resistance at moderate cost; resin ribbons provide maximum durability for harsh conditions or long-term archival labeling. For most warehouse and manufacturing workflows, wax-resin (T110A Premier II) offers the optimal cost-to-performance ratio. The perforated roll design is a productivity feature—manual label separation is faster and more reliable than cutting, reducing errors during high-volume label runs.
