Thermal Labels for Shipping, Barcodes and Warehousing

Choose reliable thermal labels for daily despatch and stock control. Our range covers the UK’s most-used sizes including 4×6″ (100×150 mm) for courier labels, plus 4×2″, 3×2″ and 3×1.5″ for product ID and barcodes. Pick from white or coloured rolls (blue, red, yellow, orange) to colour-code waves, returns and routing. We also stock fanfold 4×6″ for tidy, high-speed printing on rear-feed printers. Suitable for ecommerce fulfilment, retail, logistics, manufacturing and warehouse operations of all sizes.

All labels are direct thermal (no ink, ribbon or toner needed) with hot-melt adhesive that bonds to cardboard, film and most plastics. Options include non-perforated for smooth continuous feed, or perforated where tear-off speed matters. Tested in real UK packing lines and used with popular printers such as Zebra GK420 / ZD, Citizen CL-S and TSC DA/TE that accept 4″ media.

We hold UK stock for same-day despatch before 5 pm (Mon–Fri) via Royal Mail Tracked and DPD Next Day, with a paid Saturday option. VAT invoices are included and POs are welcomed for trade accounts. 4×6″ (100×150 mm) remains the UK’s most used courier label size.

Frequently Asked Questions

Simple answers about Thermal labels sizes, printers, adhesive and bulk buying for UK warehouses and ecommerce.

Are 4×6″ labels the right size for courier shipping in the UK?

Yes. 4×6″ (100×150 mm) is widely used for UK courier labels and works across common platforms including e-commerce, eBay, Amazon and Shopify, as well as carriers such as Royal Mail, DPD, UPS, DHL and many others.

Do your labels work with Zebra, Citizen and TSC printers?

Yes. Our 4″ rolls and fanfold stacks are used daily with Zebra GK420/ZD, Citizen CL-S and TSC DA/TE printers. Always check width, core and feed path.

What is the difference between roll and fanfold labels?

Rolls are loaded on a 1″ core inside the printer. Fanfold feeds from a rear or bottom slot and returns in a neat stack, which keeps packing areas tidy.

Should I choose perforated or non-perforated labels?
Perforated labels tear off quickly at the bench. Non-perforated labels feed smoothly for continuous, high-speed printing. Pick the style that suits your workflow.

Are your labels waterproof or for long-term outdoor use?

Direct thermal paper is designed for short-term tasks in dry conditions. Print may fade with moisture, heat or strong sunlight.

Which sizes are best for barcodes and product ID?

Use 4×2″, 3×2″ or 3×1.5″ depending on text length and barcode height. Square 4×4″ provides extra space for larger graphics.

Do you offer coloured labels for wave picking and returns?

Yes. We stock white plus blue, red, yellow and orange in 4×6″ to support colour-coded workflows.

What adhesive do you use and what does it stick to?

Hot-melt permanent adhesive designed to bond to cardboard, film and most plastics used in packing and storage.

Can I order in bulk with a VAT invoice and PO?

Yes. We provide tiered pricing, VAT invoices and accept Purchase Orders for trade accounts. Pallet shipping is available.

How fast is delivery and do you offer Saturday service?

Orders placed before 5 pm Monday–Friday despatch the same day via Royal Mail Tracked or DPD Next Day. DPD Saturday is available as a paid upgrade.
