MUNBYN 4x6 Thermal Shipping Labels 220/roll — Direct-Thermal, Waterproof & Scratch-Resistant

MUNBYN 4" x 6" thermal shipping labels are direct-thermal, waterproof, oil- and scratch-resistant labels supplied 220 per roll for fast, ink-free shipping.

These 4x6 labels are designed for high-volume shipping and barcode printing, delivering crisp, scannable text and durable adhesion without ink or toner. Each roll contains 220 labels on a 1" core, compatible with most direct thermal desktop and industrial printers that accept 4" x 6" media. Upgraded materials improve print contrast and resist smudging while an alignment hole and perforation make peeling and applying quick and accurate.

Which printers will these labels work with?

These labels are made for direct thermal printers and fit many popular makes and models. They are compatible with a wide range of Munbyn models and common direct-thermal brands, but they do not work with laser or inkjet printers and are not compatible with Brother thermal models.

• Compatible examples: Munbyn 130B, 941BP, 129B, 941U, 941AP, RW401AP, RW403B.
• Also works with many Rollo, Jadens, Nelko, Pedoolo, 450 series, 5XL printers and extra-large labels (Lw 1744907 series).
• Not for use in Brother printers or non-thermal devices—ensure your printer uses direct thermal technology.

How durable are these labels for real-world shipping?

The stock is engineered to withstand moisture, oils and rough handling so barcodes and addresses remain legible through transit. A scratch-resistant surface and upgraded thermal coating reduce the chance of smudging or fading during handling and scanning.

• Waterproof and oil-proof face stock protects printed data from spills and grease.
• Scratch-resistant surface preserves barcode integrity during packing and transport.
• Enhanced brightness and contrast improve scanner readability and courier scanning success.

How easy are these labels to use and apply?

Each roll is built for quick loading and fast application, minimizing downtime during packing. The labels include a perforation and a central alignment hole so you can tear and peel consistently and position labels precisely on packages.

• 220 labels per roll with a 1" core and 3.15" roll diameter for standard label holders.
• Perforated edge and center alignment hole speed up peeling and placement.
• Ultra-strong adhesive ensures labels stick securely to corrugated boxes, poly mailers, and other surfaces.

Are these labels safe and eco-conscious?

The paper has been tested to be free of BPA and BPS, helping reduce the use of harmful chemicals during handling. Because these are direct thermal labels, there’s no need for ink, toner, or ribbons, which cuts consumable waste and running costs.

• No BPA or BPS in the label stock, based on manufacturer testing.
• Direct-thermal printing eliminates ink, toner, and ribbon consumables.
• High-yield rolls reduce roll changes and packaging waste for busy shipping stations.

Who is this for: Small businesses, e-commerce sellers, warehouse pack stations and fulfillment centers that need reliable 4" x 6" direct thermal labels in volume. If you run a shipping desk with compatible direct-thermal printers and want durable, easy-to-apply labels without ink or ribbon maintenance, these 220-label Munbyn rolls are built to streamline packing and improve scan rates during transit.
