Sato SR15LT-53177 2x1 Gloss White Polyester Thermal Transfer Label
The Sato SR15LT-53177 (often searched as SR15LT 53177) is a synthetic polyester thermal transfer label engineered for high-volume industrial and enterprise labeling operations. With a 2" × 1" format and gloss white finish, this label delivers exceptional durability and print quality across warehouse automation, manufacturing, distribution, and asset tracking environments. Each case contains 8 rolls of 1,650 labels—13,200 total labels per case—wound on standard 1.5" core diameter spools compatible with SATO industrial thermal transfer printers. The polyester construction resists chemicals, oils, UV exposure, and moisture far better than paper labels, translating to readable labels in cold storage, outdoor racks, or chemical-adjacent areas where paper would degrade within weeks.
Key Features
- 2" × 1" label format: Versatile sizing that accommodates both dense barcodes and readable text without oversizing the label footprint. Useful for asset tags, shipping labels, and variable data printing where space is constrained—eliminates the need to choose between barcode density and physical label size.
- Gloss white polyester facestock with permanent acrylic adhesive: The permanent adhesive ensures labels stick to textured, dusty, or oily surfaces commonly found in warehouses and manufacturing floors, reducing the risk of label lift or peeling over months of handling and environmental stress. Temporary adhesive variants would require replacement within days in these conditions.
- 2 mil facestock thickness: Provides genuine synthetic durability. The added material density resists scratches, abrasion, and chemical splashes far better than 1 mil alternatives—critical when labels must survive forklifts, conveyors, or regular contact with solvents or oils.
- 1,650 labels per roll; 8 rolls per case (13,200 labels total): Bulk quantity reduces per-label material cost while the 8-roll case format balances storage footprint with inventory replenishment frequency. Typical for organizations running 500+ labels per day; cases will last 2–3 weeks at that volume, avoiding both overstocking and stockouts.
- 1.5" inner diameter core with 4.375" outer diameter: Standard SATO industrial printer spool compatibility means no adapters, no commissioning delays, and no tape hassles when loading rolls into existing printer infrastructure. Mismatched core sizes cause jams and downtime—this standard fit prevents that entirely.
- Perforated between labels: Clean, consistent tear-off dispensing. Critical for high-speed manual or semi-automated label application workflows; reduces hand fatigue and label waste from ragged tears. Poor perforation can increase scrap rates by 5–10% in high-volume environments.
- UL Recognition when printed with SATO R333A or R435B Premier I resin ribbons: UL compliance enables deployment in regulatory-sensitive environments such as electrical equipment identification, safety-critical asset tagging, and hazard labeling. Proof of compliance reduces audit friction and speeds facility certifications. Non-UL-recognized labels in these environments create liability and may require relabeling during inspections.
Integration & Compatibility
The SR15LT-53177 is purpose-built for SATO industrial thermal transfer printers using either SATO R333A or SATO R435B resin ribbons. No cross-brand ribbon compatibility testing is documented; using non-SATO ribbons voids UL Recognition and may produce inconsistent print adhesion or image durability. The 1.5" core and 4.375" OD fit all SATO industrial printer roll carriages without modification. For label printing workflows with specific ribbon or printer requirements, verify your SATO model's compatibility before ordering large case quantities.
Recommended Use Cases
Electrical and equipment identification (UL-compliant hazard and asset labels), warehouse automation and inventory management (barcode and location tags), asset tracking and lifecycle management (serialization, warranty, service history), shipping and logistics (address and tracking labels), and regulatory compliance labeling (chemical containers, equipment nameplates). The polyester construction also suits outdoor storage racks, cold-chain logistics, and environments subject to frequent washdowns or chemical splashes. Paper alternatives will fail in these conditions within weeks; the synthetic facestock delivers 6–12 months of legibility even in harsh environments.
Frequently Asked Questions
Q: Can I use the SR15LT-53177 with non-SATO ribbons?
A: No. Using non-SATO ribbons voids UL Recognition and may result in poor print adhesion and shortened label life. SATO R333A and R435B Premier I resin ribbons are validated for this label stock. Cross-brand compatibility has not been tested or documented by Sato.
Q: What is the expected shelf life of the SR15LT-53177?
A: Polyester labels stored in a cool, dry environment (15–25°C, <60% humidity) remain usable for 12–24 months. Avoid direct sunlight, high heat, or extreme humidity, as adhesive performance may degrade over time.
Q: Will these labels work in cold storage environments?
A: Yes. Polyester labels with permanent acrylic adhesive perform well in cold storage (−20°C and below). Paper labels become brittle and delaminate in these conditions; polyester remains flexible and adhesive remains effective.
Q: How many labels does each case contain?
A: Each case contains 13,200 labels (8 rolls × 1,650 labels per roll). At 500 labels per day, a case will last approximately 26 days.
Q: Are these labels suitable for chemical or oily surfaces?
A: Yes. The permanent acrylic adhesive and polyester facestock are designed to adhere to textured, oily, and dusty surfaces commonly found in warehouses and manufacturing. Paper labels will not stick reliably in these conditions.
Q: What ribbon types are compatible with the SR15LT-53177?
A: SATO R333A and SATO R435B Premier I resin ribbons. These are the only validated ribbon types for UL compliance and optimal print quality.

The Sato SR15LT-53177 is built for environments where paper labels simply will not survive. The 2 mil polyester facestock combined with permanent acrylic adhesive is the real differentiator here—label adhesion to oily, dusty, or textured surfaces is reliable over 6–12 months, whereas paper and temporary-adhesive alternatives fail within weeks. If you're running a warehouse, manufacturing floor, or cold-chain operation, this is the baseline material choice.
Technical Highlights:
- 2 mil polyester facestock + permanent acrylic adhesive: Resists chemicals, oils, UV, and moisture far better than paper. Permanent adhesive grips textured and contaminated surfaces (typical in warehouses) where temporary adhesive peels off within days.
- 13,200 labels per case (8 rolls × 1,650 per roll): At 500 labels/day, a single case lasts ~26 days. Balances per-label material cost against storage footprint and reorder frequency—no need to stock weeks of inventory or deal with frequent small shipments.
- UL Recognition with SATO R333A or R435B ribbons: Compliance matters in regulated environments (electrical equipment ID, hazard labeling, safety-critical asset tagging). Non-compliant labels trigger audit findings and forced relabeling during inspections.
Deployment Considerations:
- Ribbon lock-in: SATO R333A or R435B resin ribbons only—non-SATO alternatives void UL recognition and produce inconsistent results. If you run mixed printer brands or don't maintain ribbon inventory discipline, this becomes a sourcing constraint.
- Standard core fit: 1.5" ID / 4.375" OD matches all SATO industrial carriages with no modification needed. If you have legacy third-party printers, verify spool compatibility before ordering bulk.
This is the right choice for warehouse automation and asset tracking in high-touch, high-contamination environments—cold storage, outdoor racks, chemical-adjacent areas, or any deployment where durability over 6+ months matters more than per-unit cost. In cleaner, temperature-controlled environments, lower-cost paper alternatives may suffice; in harsh conditions, SR15LT-53177 avoids costly relabeling cycles.
