Specifications: 4 X 3 inch fanfold direct thermal labels, 1 stack with 1000 labels. Matte white thermal label paper with permanent adhesive and perforations between each label for clean separation. Prints without ink, toner, or ribbons. Barcode and Inventory Workflows: Built for 4X3 barcode stickers, SKU labels, and product identification. Ideal for bin locations, shelf tags, asset tracking, FNSKU relabeling, and internal routing where compact formatting and high-volume runs matter. Scan-Ready Prints: Direct thermal printer labels produce sharp barcodes and readable text for consistent scanning. Fanfold stacks feed smoothly through rear-feed paths to reduce skewing and alignment issues during batch printing. Reliable Adhesion: Permanent adhesive thermal label stickers bond securely to corrugated cartons, poly bags, shrink wrap, metal shelving, and plastic containers. Designed to stay in place through handling and warehouse movement. Compatibility: Thermal label printer paper works with MUNBYN, Zebra, Elton, Fargo, Intermec, Rollo, iDRPT, Polono, Jiose, K Comer, LabelRange, OFFNOVA, JADENS, Phomemo, and NefLaca. Not compatible with DYMO or Brother. These 4x3 thermal labels are designed for compact barcode and product identification workflows that require consistent output in high-SKU environments. The fanfold stack format feeds from a folded bundle rather than a spindle, supporting stable alignment and extended print runs without frequent reloads. Commonly used as barcodes and SKU labels, the 4 x 3 format fits bin locations, shelf markers, asset tracking, FNSKU relabeling, and small product packaging where space is limited but scan accuracy is critical. The compact footprint allows clear product identification while preserving room for item details, lot codes, or internal tracking data. Fanfold stacks sit flat behind or beneath compatible printers, reducing tension and minimizing lateral shifting that can occur with short formats. Perforations between each piece create consistent stopping points to support accurate positioning during batch jobs. The direct thermal construction produces dark, readable barcodes and text without ink, toner, or ribbons. This makes the format suitable for warehouse labeling, inventory control systems, and internal logistics processes that rely on dependable scanning performance. A permanent adhesive bonds securely to corrugated cartons, poly bags, shrink wrap, plastic containers, and metal shelving. Once applied, the label remains in place through routine handling and stock movement. For teams managing growing catalogs, implementing location tracking, or organizing storage systems, 4x3 thermal label paper provides a space-efficient solution for structured inventory and operational control.
