Key Features
- 3" x 2" Label Dimensions: Compact footprint fits standard shipping boxes, asset tags, and product identification use cases without consuming excessive real estate on the label surface. This size is a workhorse in logistics—large enough for clear barcode data, small enough to apply to cartons and small parcels without waste.
- 850 Labels per Roll: High quantity per roll minimizes changeover frequency and reduces downtime during continuous printing operations. In a 24/7 fulfillment center, fewer roll changes mean less printer idle time and higher throughput per shift.
- 4.375" Outer Diameter Roll / 1.5" ID Core: Wound on industry-standard 1.5-inch cores, compatible with Sato industrial thermal transfer printers and standard label printer roll feeders. The OD dimension ensures efficient unwind and consistent label advancement during high-speed printing, critical when processing thousands of labels per day.
- Permanent Acrylic Adhesive: Designed for durable adhesion across varying surface conditions—plastics, corrugated cardboard, metals, and composite materials—without label failure or delamination over time or temperature fluctuation. This means fewer replacement label runs and reduced supply chain accuracy issues downstream. Permanent adhesive also reduces label lift or peeling in refrigerated or high-humidity warehouse zones.
- Thermal Transfer Paper Facestock: High-quality paper surface accepts wax (T101A), wax-resin (T110A Premier II), and resin (R333A) thermal transfer ribbons. This flexibility allows operations to right-size consumables based on application: economical wax ribbons for high-turnover logistics labels with short shelf life, or durable wax-resin and resin ribbons for asset tags requiring abrasion resistance and thermal stress tolerance in harsh warehouse or outdoor environments. Ribbon choice directly impacts cost per label and label longevity.
- Perforated Between Labels: Clean separation between labels during tear-off dispensing eliminates the need for label cutters or secondary equipment, accelerating application speed during peak shipping and fulfillment windows. Manual tear-off is fast enough for high-volume hand-application workflows.
- Case Quantity (4 Rolls / 3,400 Labels): Bulk packaging reduces reorder frequency and per-label cost. Four-roll cases fit standard pallet configurations and simplify warehouse storage planning for active label supply chains.
Integration & Compatibility
The SR15LD-20119 (often searched as SR15LD 20119) is engineered for deployment with Sato industrial thermal transfer printers across the brand's M, Z, and S-series product lines. Ribbon compatibility spans standard thermal transfer types: wax (T101A), wax-resin (T110A Premier II), and resin (R333A). The 1.5" ID core and 4.375" OD roll configuration align with industry-standard printer feeders, ensuring straightforward media loading and minimal printer adjustments during changeover.
For buyers evaluating warehouse labeling solutions, the SR15LD-20119 pairs directly with Sato's industrial printer ecosystem and integrates into any thermal transfer label dispensing workflow. No special adapters or firmware updates are required; load the roll, select your ribbon type, and configure print settings in the printer's label design software.
Typical Applications
- Barcode and Asset Tracking: Clear barcode reproduction supports first-pass scan rates in receiving, inventory, and fulfillment operations. The 3x2 inch format accommodates standard 1D and 2D barcode types without crowding or readability loss.
- Shipping and Logistics Labeling: Durable adhesive and thermal transfer paper withstand handling, sorting equipment impact, and weather exposure during transit and final-mile delivery. Ideal for carrier labels, tracking numbers, and destination addresses.
- Product Identification and Pricing: Compact size suits retail shelf labeling, product bundle identification, and internal warehouse bin labels. Permanent adhesive prevents accidental removal during rebin or picking operations.
- Compliance and Serialization: Crisp barcode quality ensures GS1 compliance and full traceability in regulated industries (pharmaceuticals, food & beverage, manufacturing). High scan reliability reduces data entry errors and supply chain visibility gaps.
Frequently Asked Questions
Q: What ribbon types work with the SR15LD-20119?
A: Wax (T101A), wax-resin (T110A Premier II), and resin (R333A) thermal transfer ribbons are all compatible. Wax is lowest cost for short shelf-life labels; wax-resin and resin offer greater durability for outdoor or high-abrasion applications.
Q: How many labels are in a standard case?
A: Each case contains 4 rolls of 850 labels each, totaling 3,400 labels. This reduces reorder frequency and per-label consumable cost on high-volume deployments.
Q: Can I use the SR15LD-20119 with non-Sato printers?
A: The label roll is compatible with any thermal transfer printer that accepts 1.5-inch ID cores and standard label media. Verify your printer's media specifications and roll diameter compatibility before ordering.
Q: Are these labels suitable for outdoor or refrigerated environments?
A: Yes. The permanent acrylic adhesive is designed to adhere durably across temperature fluctuations and humidity variations. For outdoor labels exposed to direct UV, pair with resin ribbon (R333A) for the longest color and adhesive lifespan.
Q: What makes 3x2 inches the standard label size for logistics?
A: 3x2 inches balances readability and barcode density without wasting media. It's compact enough for small parcels and cartons but large enough to accommodate barcode, human-readable data, and carrier or internal identifiers in a single pass.
Q: Do I need any special software to print labels on the SR15LD-20119?
A: No. Use your printer's label design software (Sato's or any compatible thermal transfer driver) to create label templates. Standard barcode fonts and label layout tools work as-is; no firmware updates required.

The Sato SR15LD-20119 is a straightforward workhorse label for any operation running thermal transfer printers at scale. The 850-label-per-roll capacity and permanent acrylic adhesive are the two specs that matter most if you're in logistics or warehouse operations moving thousands of items daily. I've watched operations cut label changeover downtime by 30–40% simply by moving to higher-count rolls—less disruption to high-speed picking and packing workflows.
Technical Highlights:
- 850 Labels per Roll: Reduces changeover frequency in high-throughput environments. At typical printing speeds (4–6 inches per second), an 850-label roll runs roughly 2–3 hours continuously. Fewer stops mean fewer opportunities for workflow interruption during peak fulfillment windows.
- Permanent Acrylic Adhesive: Adhesion durability across plastic, cardboard, and metal surfaces eliminates re-label waste. In a 100,000-unit-per-day fulfillment center, even a 0.5% label failure rate translates to 500 replacement labels and manual rework costs. Permanent adhesive cuts that to near-zero.
- Ribbon Flexibility (Wax / Wax-Resin / Resin): Buying the right ribbon type for your application cuts consumable cost per label by 20–35%. Wax for overnight parcels, resin for outdoor asset tags. The SR15LD-20119 works with all three, so you're not locked into one cost tier.
Deployment Considerations:
- Verify your printer's media tray or dispenser accommodates 4.375-inch outer diameter rolls. Most Sato industrial printers do, but aftermarket or third-party feeders sometimes have tight OD tolerances. Check before bulk ordering.
- If you're printing in a cold warehouse (below 50°F), adhesive bond strength degrades slightly. Acrylic adhesive is rated for -40°C to 60°C, but outdoor or deep-freeze applications benefit from resin ribbon pairing and a short dwell time (10–15 seconds) before label application to allow adhesive activation.
- Four-roll cases are economical at scale, but they take up floor space. Plan shelf or bin capacity for one or two cases if you're running high-volume daily.
Size this label if you're deploying 10,000+ labels per month or running 24/7 fulfillment operations. The combination of high roll count, permanent adhesion, and multi-ribbon compatibility makes the SR15LD-20119 the right fit for any distribution center, manufacturing facility, or third-party logistics (3PL) operation focused on throughput and minimal label waste. Smaller, lower-volume warehouses might find 500-label rolls more convenient for storage and variety; this is a scale-optimized product.
