Direct Thermal Labels

Direct Thermal Labels for Shipping, Barcoding and Retail Pricing

Direct thermal labels are the workhorse of Australian shipping, retail and logistics operations. These labels print using heat alone, with no ink, toner or ribbon required, making them the most cost-effective labelling solution for high-volume applications. Vision Supply stocks a full range of direct thermal label rolls in every popular size, from compact 40x28mm barcode labels through to standard 100x150mm shipping labels, with core sizes to match desktop, commercial and industrial thermal printers.

Every direct thermal label roll in our range is manufactured from quality thermal paper with a consistent coating that produces sharp, scannable barcodes and clear text on first pass. We supply businesses across Australia, from small eCommerce sellers printing a handful of shipping labels daily to large warehouse operations processing thousands of labels per shift.

How Direct Thermal Label Printing Works

Direct thermal printing relies on a chemical reaction between the printer's heated print head and the label's thermochromic coating. When the print head applies focused heat to specific points on the label surface, the coating darkens to form text, barcodes and graphics. Because the image is created by heat alone, there is no ribbon to load, replace or dispose of. This makes direct thermal printing faster to set up, simpler to maintain and cheaper to run per label than alternatives like laser, inkjet or thermal transfer printing.

The trade-off is durability. Direct thermal prints are sensitive to heat, prolonged sunlight and abrasion. This makes them ideal for short-to-medium-term applications such as shipping labels, warehouse pick labels, retail pricing, supermarket scale labels and receipt printing, but less suitable for labels that need to last years outdoors or withstand harsh chemical exposure. For those situations, thermal transfer labels paired with a resin ribbon are the better choice.

Direct Thermal Label Sizes and Core Options

We stock direct thermal labels in a wide range of sizes to cover every common application in Australian business. The 100x150mm format (also referred to as 4x6 inch) is the Australian standard for shipping labels and is compatible with Australia Post, StarTrack, Sendle, Aramex and all major courier platforms. We carry this size in rolls of 350 and 1,000 labels with both 25mm and 76mm cores.

For barcode and product identification, popular sizes include 100x100mm, 100x73mm, 50x28mm and 40x28mm. Supermarket and fresh food operations commonly use 56x25mm scale labels and 60x40mm pricing labels. We also stock specialty formats including 40x140mm produce crate labels and 102x150mm address labels.

Core size matters because it determines printer compatibility. Our 25mm core labels fit desktop printers like the Zebra GK420d, GX420d, ZD420 and Brother QL series. Our 40mm core labels are designed for mid-range commercial printers. Our 76mm core labels suit high-speed industrial printers such as the Zebra ZT410, ZT610, Sato CL4NX and TSC TTP series.

Direct Thermal Labels for Australian Shipping and eCommerce

If you run an online store, fulfilment centre or warehouse, direct thermal shipping labels are an essential consumable. The 100x150mm perforated label roll is the standard format accepted by every major Australian carrier. Our perforated labels separate cleanly from the roll backing for fast, jam-free printing at high speed. Permanent adhesive ensures each label stays securely attached to cartons, satchels, bags and poly mailers throughout the entire delivery journey.

For businesses printing more than 200 labels daily, our 1,000-label rolls on 76mm cores reduce roll changes and keep throughput high. Smaller operations can start with our 350-label rolls on 25mm cores and scale up as order volumes grow.

Fluorescent and Coloured Direct Thermal Labels

Need high-visibility labels for markdown pricing, warehouse sorting or promotional tagging? Our fluorescent direct thermal labels are available in pink, yellow, orange, green and blue. These bright labels print with the same ease as standard white thermal labels but deliver instant visual impact on the shelf or in the warehouse. Fluorescent labels are commonly used for clearance pricing, colour-coded inventory systems, priority shipment flagging and retail promotions.
