SATO SR15LD-20122 4x3 Thermal Transfer Paper Label

The SATO SR15LD-20122 is a 4" x 3" thermal transfer paper label engineered for high-volume industrial and enterprise labeling operations. Designed for seamless integration with SATO industrial thermal transfer printers, this label stock delivers crisp barcode reproduction, clear text rendering, and reliable adhesion across warehouse, manufacturing, and distribution environments.

Key Features

4" x 3" thermal transfer paper facestock with permanent acrylic adhesive

650 labels per roll; 4 rolls per case (2,600 total labels)

Perforated between labels for efficient tear-off dispensing

1.5" inner core diameter with 4.375" outer diameter

Compatible with wax (T101A), wax-resin (T110A Premier II), and resin (R333A) ribbons

Optimized for carton, packaging, and product surface adhesion across temperature ranges

Technical Specifications

Material Composition: The thermal transfer paper facestock ensures excellent print contrast and image clarity for barcodes, QR codes, and text-based identification. The permanent acrylic adhesive provides reliable adhesion to corrugated cartons, plastic cases, metal surfaces, and labware—critical for cold chain, ambient, and heated storage conditions.

Ribbon Compatibility: The SR15LD-20122 supports three ribbon formulations, allowing users to optimize for application requirements. Wax ribbons provide cost-effective printing on coated surfaces; wax-resin ribbons offer enhanced durability for moderate-temperature environments; resin ribbons deliver maximum print permanence for harsh chemical, moisture, and abrasion exposure.

Roll Configuration: Each case contains 4 rolls of 650 labels, totaling 2,600 labels. The 1.5" inner core and 4.375" outer core diameter are standard SATO printer specifications, ensuring drop-in compatibility without reconfiguration.

Applications

Shipping & Logistics: Address labels, packing slips, and package identification

Warehouse Management: Bin location labels, inventory tags, and asset tracking

Manufacturing: Work-in-progress tracking, batch identification, and product labeling

Distribution: Multi-carrier compliance labels and barcode-driven order fulfillment

Retail: Price tags, product labeling, and promotional stickers

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The SR15LD-20122 strikes a practical balance between label capacity and print quality for mid-to-high-volume operations. The 4" x 3" format accommodates full GS1-128 barcodes, shipping routing information, and human-readable text without sacrificing readability or label density. The perforated design minimizes operator handling time and reduces label curl during dispensing.

The three-ribbon compatibility strategy reflects SATO's modular approach: organizations can start with cost-effective wax printing and upgrade to wax-resin or resin formulations as application requirements change—without replacing label stock. This flexibility is valuable in environments where label durability requirements vary by product line or shipping destination.

For operations processing 2,600+ labels per case, the four-roll configuration reduces changeover frequency while maintaining manageable roll weight and storage footprint. Best practice: integrate roll-tracking into inventory management systems to prevent unexpected stockouts during peak shipping periods.
