SATO SF300 DuraMark 4x6 Gloss White Polyester Label – SR30LT-18386
The SATO SR30LT-18386 is a premium 4" x 6" synthetic polyester thermal transfer label engineered for demanding industrial and enterprise environments. Built on the SF300 DuraMark platform, this gloss white polyester facestock with permanent acrylic adhesive delivers exceptional durability where standard paper labels fail. Each case includes 4 rolls of 1,000 labels (4,000 total) wound on 3" inner diameter cores with 8" outer diameter, configured for seamless integration with SATO industrial thermal transfer printers.
Key Features
- Gloss White Polyester facestock with permanent acrylic adhesive for reliable industrial bonding
- SF300 DuraMark construction for superior chemical, heat, and UV resistance
- 4" x 6" label format with perforation for efficient tear-off dispensing
- 1,000 labels per roll, 4 rolls per case (4,000 labels total)
- 3" core ID with 8" outer diameter for SATO printer compatibility
- UL Recognized when printed with SATO R333A or R435B Premier I resin ribbons
- Thermal transfer print method for crisp, durable barcode and text imaging
Technical Highlights
The synthetic polyester construction of the SR30LT-18386 provides excellent resistance to oils, solvents, temperature extremes, and outdoor UV exposure—critical for asset tracking labels, electrical equipment identification, and harsh-environment applications. The gloss finish enhances barcode readability and image clarity, while the permanent acrylic adhesive ensures labels remain affixed through handling, washing, and environmental stress. Perforation between labels enables rapid, hands-free dispensing in wound-in orientation, reducing operational friction in high-volume labeling workflows.
When paired with SATO R333A or R435B Premier I resin ribbons, these labels achieve UL Recognition status, meeting regulatory compliance requirements for electrical safety, equipment labeling, and certified asset identification programs.
Ideal Applications
The 4" x 6" format and synthetic durability make the SR30LT-18386 suitable for:
- Barcode and asset tracking in manufacturing and warehousing
- Shipping and logistics labeling
- Electrical equipment and component identification
- Equipment maintenance and certification labeling
- Outdoor and harsh-environment asset management
- Chemical and temperature-resistant product identification

The SR30LT-18386 represents a strategic choice for operations requiring label longevity beyond standard thermal paper. Synthetic polyester labels cost more per unit but deliver measurable ROI in high-churn environments—chemical plants, outdoor facilities, and temperature-cycling operations see dramatically reduced label deterioration and reprinting costs. The UL Recognition pathway (via certified resin ribbons) is essential for regulated industries; verify your specific ribbon pairing early to ensure compliance.
For organizations already running SATO industrial equipment, this label integrates seamlessly without printer firmware or configuration changes. The 4,000-label case quantity suits mid-to-large operations; smaller deployments may find initial spend higher but benefit from extended shelf life and minimal waste due to superior adhesion durability.
