Durable Labels for Warehousing, Shipping & Field Applications
What sets Ultramax DT apart from ordinary direct thermal paper is its advanced topcoat technology, which delivers durability far closer to thermal transfer labels than standard paper stock. These labels are built for demanding applications across warehousing and logistics, shipping and parcel delivery, retail, inventory management, and field service — anywhere labels face constant handling, moisture, abrasion, and temperature changes. The strong permanent adhesive bonds securely to corrugated boxes, plastic totes, and packaging, keeping your barcodes scannable and human-readable long after conventional labels would fade, smear, or fail a scan.
Typical Applications
- Shipping & parcel labels printed on the spot from a mobile printer
- Warehouse receiving & put-away labeling at the dock or in the aisle
- Inventory & asset tracking that survives months of handling
- Field service & delivery routes where labels are printed and applied on location
- Retail back-room & stockroom labeling applications
Can Ultramax DT Paper Labels Be Used Outdoors?
Yes — these labels are rated for both indoor and outdoor use. Ultramax DT paper labels are engineered to withstand UV exposure and direct sunlight, perform in heat up to 70°C (158°F) and sub-zero cold, and remain 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, and saltwater exposure.
Whether your labels live on a pallet in the summer sun, a package riding a delivery route through the seasons, or a tote that gets washed down regularly, Ultramax DT keeps working — no ribbon, no fading, no failed scans.
