Ultramax DT Mobile Direct Thermal 4" x 6" Durable BOPP Labels – 90/Roll – 0.75" Core | 2.22" OD
Ribbon-free, weatherproof direct thermal labels engineered for mobile printing — indoors and out.
The Ultramax DT Mobile Direct Thermal 4" x 6" Durable BOPP Label combines premium synthetic durability with true on-the-go convenience. Built on a tough polypropylene (BOPP) film with an advanced patent-pending topcoat, these labels print sharp, dark barcodes and text on any direct thermal mobile printer — no ribbon required — and then stand up to the real-world conditions that destroy ordinary paper labels. Each roll contains 90 labels on a 0.75" core with a maximum roll diameter of 2.22 inches, and features perforations for easy tearing plus a black sensor mark printed on the back for accurate media detection. Price is per roll, with 24 rolls per case (sold by the case).

Durable Labels for Demanding Applications
What good is a label if it can't survive the job? Ultramax DT 4" x 6" BOPP labels are engineered to withstand the scuffing, moisture, temperature swings, and chemical exposure that cause standard direct thermal labels to fail. The permanent all-temperature adhesive grabs firmly to corrugated boxes, plastic totes, pallets, and bins — and holds on through cold storage and rough handling.
These durable labels are ideal for a wide range of applications, including:
- Shipping & parcel labels that stay scannable from dock to doorstep
- Warehouse rack, bin, and shelf labeling built for years of indoor use
- Outdoor asset and equipment labeling exposed to sun, rain, and weather
- Vehicle & fleet labeling for auto lots, rental fleets, and auction houses
- Retail, nursery & garden centre tags that resist moisture and humidity
- Manufacturing & work-in-progress tracking on the plant floor
- Field service & logistics labels printed and applied on the spot
The Best Direct Thermal Labels for Outdoor Use
If your labels live outside, ordinary direct thermal paper simply won't cut it. Ultramax DT labels are specifically engineered for outdoor performance: they can be exposed to direct sunlight and UV rays, heat up to 70°C (158°F), and cold temperatures down to -65°F (application as low as -20°F) while remaining scannable and human-readable for up to 1 year outdoors — and up to 2 years in indoor warehouse conditions.
They're also chemical resistant, standing up to alcohol, bleach, IPA, ammonia, acetone, xylene, and saltwater. And because they're BPA-free, BPS-free, and No-Phenols-Added, they're as safe for your team as they are tough on the job. Whether it's a pallet sitting in the summer sun or a tote washed down with cleaning agents, these labels keep working.
