Designed for shipping and labeling tasks, these 4 x 6 inch direct thermal labels are used for printing postage labels, shipping labels, and package identification. The label size provides space for addresses, tracking information, and barcodes used in order fulfillment and returns processing. The roll format supports continuous printing without sheets or manual cutting. Each roll uses direct thermal label paper that prints black text on a white background and works with compatible direct thermal printers. Text, numbers, and barcodes remain readable for sorting, handling, and delivery processes. The matte white surface helps provide clear contrast for printed information on boxes, poly mailers, and envelopes. Perforations between each label allow easy separation during application. The adhesive backing is designed to attach to common packaging materials such as cardboard boxes, paperboard, and poly mailers used in shipping and fulfillment operations. These labels are commonly used for postage labels, shipping labels, return labels, carton labeling, and package relabeling in e-commerce, warehouse, and office environments. The roll format helps support consistent label feeding during printing for order processing and shipping workflows.
