These 4 x 2 inch opaque white blockout laser labels are built to fully conceal existing printed text, barcodes, and addresses on boxes, mailers, envelopes, and other packaging surfaces. The opaque face stock prevents underlying print from showing through — a critical requirement when relabeling outbound shipments, correcting mislabeled cartons, or applying custom product or mailing labels over prior markings.

Laser printer compatibility makes these labels practical for warehouse receiving docks, fulfillment centers, retail distribution operations, and manufacturing facilities where high-volume relabeling is routine. A Microsoft Word template is available for formatting, allowing fast setup without specialized label software.

Each case contains 1,000 labels and weighs approximately 2.98 lbs, keeping storage and handling requirements minimal. Labels are sold by the case and ship via parcel carrier.
