Applications

Use this material for indoor packing lists, general-purpose tickets and work-in-process tags where direct thermal printing fits your workflow. Match the roll dimensions to your printer before ordering; the material family alone does not establish printer compatibility.

Up to 25-year image legibility under archival conditions

Zebra specifies that images can remain legible for up to 25 years when properly formed and when receipts are handled and stored under the required conditions. Protect archival receipts from light, heat, water, solvents, cleaners, plasticizers and oils, including vegetable and skin oils. Store with compatible materials below 77°F at 45–65% relative humidity. Image durability depends on the energy used during printing. This is a conditional archival claim, not an unconditional service-life guarantee.

Printer fit and application testing

Confirm that your printer accepts 4-inch-wide media, a 0.75-inch core, a 2.25-inch roll outer diameter and 3.2 mil paper. Verify appropriate print settings for this exact material with Zebra or your printer documentation. Pre-test the paper against your intended end-use requirements.

Exposure limitations

The material sheet marks alcohol, ammonia, bleach, IPA, gasoline, grease, oil, acetone, IR reflow, MEK, TCE and xylene as not recommended. Do not treat the paper as suitable for outdoor exposure or as waterproof.
