Direct Thermal Polypropylene Label Designed to Withstand Extreme Heat and Cold, Water Resistant and Exposure to a Wide Range of Chemicals. Zebra's Most Rugged Synthetic Direct Thermal Label Suitable for Demanding Environments and Applications

When you need a direct thermal label that will withstand the most demanding environments, Zebra’s ThermaLock 4100D delivers. This direct thermal label can handle extreme cold, direct sunlight, rain, snow and exposure to a wide range of chemicals. You get a unique combination of benefits — the simplicity of direct thermal printing, with great outdoor performance and lifecycle. The label remains crisp and highly legible with easy-to-scan barcodes for up to 12 months outdoors — and even longer in indoor and shaded areas. Compatibility with Zebra’s direct thermal mobile, desktop and industrial printers enables maximum application flexibility — use it in indoor and outdoor facilities, as well as out in the field. On-the-spot printing is exceptionally easy — there are no ribbons for workers to carry or change. And the new technology in this next generation of Zebra’s trusted and popular ThermaLock 4000D increases chemical and moisture resistance, making the ThermaLock 4100D Zebra’s most rugged direct thermal label yet.

  • Designed for the toughest environments and applications
    While traditional direct thermal media are susceptible to UV light, heat and chemicals, the ThermaLock 4100D uses a unique print technology to produce an image that will last up to a year — even in the most demanding conditions. The labels are designed to withstand temperatures — as low as -65°F/-54°C and up to 165°F/74°C — as well as exposure to sunlight, a wide range of chemicals, moisture and more. And the permanent acrylic adhesive keeps these labels in place, regardless of the environmental conditions when they were applied.
  • Save time and improve labeling accuracy with on-the-spot printing
    The ability to print labels with unique data at the point of application improves worker productivity and workflow efficiency. The need to travel back and forth to a centralized desktop printer to retrieve labels and the opportunity to inadvertently apply the label to the wrong asset are eliminated.
  • Health- and environmentally-conscious engineering
    These BPA/BPS-free/Phenol-free labels protect the environment and the safety of everyone who comes in contact with them — from workers who load label stock into the printers and apply the labels to customers who purchase labeled goods.
  • High quality, trouble-free printing
    This premium grade label is specially coated to provide optimal print performance at up to 4 inches per second (4 ips).
  • The flexibility for many indoor and outdoor labeling applications
    ThermaLock 4100D labels are ideal for: shipping containers in a port; inventory in outdoor areas — such as a warehouse yard, garden center or vehicles in an outdoor auction yard; work-in-process and raw materials in a manufacturing plant; no-fade citation labels that can be printed even in the rain or snow; smudge-free specimen labels in a laboratory; blood bags collected at local blood drives; plants at a farm or indoor growing facility and more.
  • Simplified printing — no ribbon required
    The ThermaLock 4100D is compatible with Zebra’s direct thermal mobile, desktop and industrial printers, providing all the benefits of direct thermal printing — there’s no ribbon to stock, monitor and replenish.
