Label roll SEIKO SLP-OPSRL — blue/white labels, 10.1 cm × 5.4 cm, 220 labels per roll

SEIKO SLP-OPSRL blue/white label roll contains 220 rectangular thermal labels per roll, each measuring 10.1 cm × 5.4 cm. The labels have a white printable surface with a blue underside designed to block underlying text or graphics. Intended for thermal/label printers compatible with SEIKO roll dimensions, these labels are suitable for applications where visibility, re-coding or over-labeling is required.

Advantages

The blue-backed labels provide reliable opacity to conceal previous text, barcodes or markings, enabling clear re-labelling and re-bar-coding. A uniform white printable surface ensures consistent print quality for text, barcodes and graphics. The roll format with 220 labels simplifies loading and reduces printer downtime. Labels are sized to accommodate standard product, shipping and inventory information while remaining compatible with thermal printing workflows.

Suitable for (tasks / use cases)

• Re-labelling products and packaging
• Over-labeling existing barcodes for re-bar-coding
• Shipping and address labels that require covering previous markings
• Inventory tagging in retail, warehousing and office environments
• Security or identification where underlying information must be concealed

Key specifications

• Label dimensions: 10.1 cm × 5.4 cm
• Labels per roll: 220
• Color: white printable face with blue underside for opacity
• Format: rectangular roll labels for thermal/label printers
• Printable surface suitable for text, barcodes and simple graphics

How to use

Load the roll into a thermal/label printer compatible with SEIKO roll dimensions following the printer manufacturer’s instructions. Adjust printer settings for label size (10.1 cm × 5.4 cm) and media type to achieve optimal print density and barcode readability. Feed the labels so the white printable face receives the print output while the blue underside faces the roll core. Test-print one label to confirm alignment and print quality before processing larger batches.

Usage recommendations

For best results, store rolls in a cool, dry place away from direct sunlight and extremes of temperature. Use labels within the printer’s recommended media specifications and run a test print when changing printers or media to ensure barcode scanners and downstream systems read the re-bar-coded labels reliably.
