Abbott Label 4" x 6-1/2" White Direct Thermal Labels 900 per roll 4 rolls per carton

Product identity

These white direct-thermal labels measure 4" x 6-1/2" and come 900 to a roll with four rolls per carton. They are aimed at businesses that print high volumes of shipping or inventory tags in dry indoor environments. The permanent acrylic adhesive bonds well to corrugated board and plastic surfaces and meets FDA CFR 175.105 for indirect food contact. Buyers who need colour printing or waterproof outdoor durability should choose a different technology.

Sustained printing behaviour

The Fasson Direct-Therm 300LD facestock carries a high-sensitivity coating that keeps print density consistent across long runs without a ribbon. Because the coating is non-topcoated, exposure to moisture, oil, alcohol or other liquids will degrade the thermal layer and cause fading or unreadable barcodes. The labels are designed for dry applications only, so they perform reliably in climate-controlled warehouses but not in refrigerated or wash-down areas.

Installation and common issues

Each roll is perforated between labels, allowing clean separation on most industrial direct-thermal printers. Misalignment usually stems from incorrect sensor calibration or worn platen rollers rather than the media itself. Adhesive ooze can occur if rolls are stored flat under heavy weight for extended periods; storing them upright in original packaging prevents this. Ensure the printer’s heat setting matches the 300LD coating sensitivity to avoid over- or under-heating.
