Zebra 10002627 Z-Ultimate 4000T White Gloss Polyester Labels
Overview
The Zebra Z-Ultimate 4000T White label — part number 10002627 — is a premium thermal transfer polyester label built for environments where paper simply won't hold up. At 4 x 2.5 inches (101.6 x 63.5mm) with a high-gloss finish and high-performance permanent acrylic adhesive, these labels are specified for UL compliance marking, top-side PCB identification, automotive part labeling, and product identification on finished goods that will see outdoor exposure, chemical washdown, or wide temperature swings. If you've had labels delaminate off a part rack mid-cycle or fade off a PCB after conformal coating exposure, this is the label stock to reach for.
Each box of 10002627 contains 4 rolls of 2,240 labels each — 8,960 labels per box — wound on a 3-inch core compatible with Zebra's industrial and desktop thermal transfer printers. Thermal transfer printing (ribbon required) locks resin or wax-resin ink into the polyester surface for print permanence that direct thermal paper can't match on permanence or scratch resistance.
Key Features
- 3-Year Outdoor Durability: The Z-Ultimate 4000T polyester substrate resists UV, moisture, and atmospheric exposure rated to 3 years outdoors — relevant for exterior asset tags, utility equipment labels, or anything mounted on enclosures that live outside. Standard paper labels begin degrading in weeks under the same conditions.
- 300°F Temperature Resistance: Rated to 300°F (approximately 149°C), these labels survive autoclave-adjacent environments, wave solder proximity, and under-hood automotive applications where label stock and adhesive integrity matter. That ceiling puts them well above what polypropylene or paper-based alternatives can handle.
- Permanent Acrylic Adhesive: The high-performance permanent acrylic adhesive bonds reliably to metals, plastics, and coated surfaces common in electronics manufacturing and industrial assembly. It won't creep or flag at temperature — important when a label on a PCB must still be readable at end-of-life inspection.
- Freeze-Thaw Cycle Resistance: Repeated freeze and thaw cycles do not cause delamination or adhesive failure — making these appropriate for cold-chain asset tracking, refrigerated warehouse equipment, or outdoor environments in northern climates that cycle hard seasonally.
- Gloss Finish with Topcoat: The high-performance coated gloss surface delivers sharp barcode print contrast for scanner-readable codes and is topcoated for fanfold compatibility. If you're running fanfold label stock through a print-and-apply applicator, the topcoating prevents inter-leaf adhesion.
- Chemical Resistance: Rated for resistance to moderate chemical exposure — smear and scratch resistance is described as unparalleled in the product documentation. For PCB labeling that may see flux residue, isopropyl alcohol cleaning steps, or light solvent exposure, that durability matters more than it sounds.
- FDA 175.105 Compliance: Meets FDA 175.105 for indirect food contact — meaning these labels can be used on packaging, equipment, or surfaces that may incidentally contact food without triggering indirect food contact compliance gaps. Relevant for food manufacturing facilities labeling equipment or secondary packaging.
- High-Volume Pack Format: 2,240 labels per roll, 4 rolls per box = 8,960 labels per order unit. For high-throughput label operations on Zebra industrial printers, the roll count reduces changeover frequency and keeps lines running.
- 3-Inch Core: The 76.2mm (3-inch) core is the standard for Zebra industrial-class thermal transfer printers. Verify your printer model supports a 3-inch core before ordering — some Zebra desktop models are keyed for 1-inch cores only.
Integration and Compatibility
The 10002627 is a thermal transfer label — it requires a ribbon (wax-resin or full resin recommended for polyester substrates) and a thermal transfer-capable label printer. Zebra's own Z-Select, ZT Series, and ZD Series industrial and desktop printers accept this roll format on 3-inch cores. For PCB labeling and UL compliance marking, pair with a resin ribbon to maximize chemical and abrasion resistance — wax ribbons will not match the durability spec on a polyester face stock.
The 4 x 2.5-inch format is a common general-purpose label size for product identification, shipping compliance, and serialized asset tags. If your label supply workflow is managed through Zebra's ZPL-based printers, this size can be called directly in ZPL programming without media calibration changes if your printer is already configured for this format.
UL-listed compliance labels and top-side PCB labels often require specific adhesive and substrate combinations for regulatory purposes — verify with your compliance engineer that the permanent acrylic adhesive and polyester substrate combination meets your specific UL or IPC standard before committing to a run.
Frequently Asked Questions
Q: Does the Zebra 10002627 work with direct thermal printers?
A: No. The Z-Ultimate 4000T is a thermal transfer label and requires a ribbon and a thermal transfer printer. It will not produce a print image in a direct thermal-only printer.
Q: What ribbon type should I use with the 10002627 on a polyester substrate?
A: For full durability performance — especially chemical resistance and scratch resistance — pair with a full resin ribbon. Wax-resin ribbons will print but will not deliver the same resistance properties on the polyester face stock.
Q: How many labels are included in a box of 10002627?
A: Each box contains 4 rolls of 2,240 labels each, for a total of 8,960 labels per box. Each roll is wound on a 3-inch (76.2mm) core.
Q: Are these labels suitable for outdoor use?
A: Yes. The Z-Ultimate 4000T polyester substrate is rated for up to 3 years of outdoor exposure, including UV and moisture resistance.
Q: Are the 10002627 labels FDA compliant for food contact applications?
A: They meet FDA 175.105 for indirect food contact, meaning they are appropriate for labeling food packaging or equipment surfaces where incidental food contact may occur. They are not intended for direct food contact.
Q: Can these labels handle high-temperature environments?
A: Yes. The Z-Ultimate 4000T is rated to 300°F (approximately 149°C), making it suitable for applications near heat sources, automotive under-hood environments, and some electronics manufacturing processes.
I spec the 10002627 whenever a project has a hard outdoor durability or temperature requirement that rules out paper or polypropylene — the 3-year outdoor rating and 300°F ceiling on the Z-Ultimate 4000T are real, tested thresholds, not marketing estimates. This is the label stock that belongs on exterior electrical enclosures, PCB top-side serialization, and automotive part marking where the label has to outlast the inspection cycle.
Technical Highlights:
- 300°F Temperature Resistance: That ceiling (approximately 149°C) covers most industrial heat exposure scenarios short of direct oven processing — automotive under-hood, reflow soldering proximity, and industrial dryer environments all fall within spec.
- Permanent Acrylic Adhesive: The high-performance permanent acrylic formula maintains bond integrity through freeze-thaw cycling and moderate chemical exposure — the combination of substrate and adhesive is what makes this appropriate for UL compliance and PCB labeling, not just the face stock alone.
- 8,960 Labels per Box: Four rolls of 2,240 on 3-inch cores means fewer changeovers on a high-volume line. For serialized PCB labeling or compliance marking runs, that roll count keeps the printer running longer between interventions.
Deployment Considerations:
- This is a thermal transfer-only label — confirm your printer supports TT mode and is loaded with a resin or wax-resin ribbon before pulling from stock. Running polyester face stock with a wax ribbon will produce readable print but will not hold up to the chemical or scratch resistance the spec implies.
- The 3-inch core is standard for Zebra industrial printers (ZT410, ZT420, ZT610 series) but not universal across all desktop models — verify core compatibility before committing to this SKU at volume.
Best-fit scenario: electronics manufacturing or automotive parts operations running serialized compliance labels that must survive the full product lifecycle — from assembly line to field service inspection — without reprint or relabeling. That's where the durability spec justifies the premium over general-purpose paper label stock.
