Ultra-thin and self-laminating labels on rolls

Brady B461 and I-Label M5937

Brady’s B461 material is a self-laminating polyester for small diameters. You print on a white area and wrap a transparent overlaminate strip around it to seal the print against moisture, friction, and solvents.

Our house reference M5937 is the I-Label equivalent of this material (same composition and performance). These labels have been developed for laboratory environments and perform well in liquid nitrogen and autoclaves.

  • Ultra-thin and flexible: adds hardly any diameter; fits easily into racks, holders, and cap handlers

  • Self-laminating shield: more resistant to abrasion, moisture, and commonly used lab solvents

  • Made for the lab: Brady says B461 is suitable for environments where the label is laminated around itself.

  • Thermal-transfer sustainability: Sharp 1D/2D codes with the right ink ribbons

  • Versatile: for vials, centrifuge tubes, test tubes, straws, drinking straws… for flat and curved surfaces

  • Wide range of printers: Brady’s portable M-series and benchtop models

Ultra-thin and self-laminating labels on rolls: print protected against moisture and friction

Ultra-thin, self-laminating labels on a roll are the most commonly used labelling materials for small diameters. The white print area is protected by a transparent overlaminate strip that is resistant to moisture, friction and solvents.

Wrap-around with protective laminate

The label is wrapped around the tube; the tail laminates the printed area and makes the barcode resistant to condensation, water baths, and chemicals. These labels are designed for cryogenic storage, but can also withstand autoclave cycles.

Ultra-thin carrier, fits in racks

The ultra-thin construction with long overlap tail is designed to stay close to the surface, preventing racks from jamming and labels from curling. The thin polyester base with clear overlaminate keeps your tubes stackable and scannable.

Fine detail, durable print

Print with thermal transfer for sharp barcodes and long-lasting contrast retention. For B461 Brady labels, black resin ribbons from the R4300 family are a common choice for chemical resistance and smudge resistance.
