RONGTA 4x6 direct thermal shipping labels provide a convenient labeling supply for e-commerce sellers, warehouses, offices, small businesses and home shipping stations. The package includes one roll with 500 white labels, each measuring 4 by 6 inches for standard shipping and package-labeling applications. The direct thermal surface uses heat to create printed text and barcodes, so no ink, toner or ribbon is required. When used with a compatible direct thermal label printer, the labels are designed to produce clear, readable shipping information for routine order fulfillment. Strong adhesive helps the labels remain attached to common package surfaces during normal handling and transportation. The label surface is also designed to resist scratches, water and oil to help keep printed information legible through typical shipping workflows. Use these thermal shipping labels only with label printers that support 4 x 6-inch roll media. Before ordering, confirm your printer’s supported label size and roll requirements.
