Direct Thermal Labels (4x6, 4x4, 100x150mm) – Shipping Label Rolls UK

Direct thermal labels are the fastest way to print shipping labels, barcode labels and warehouse ID labels without ink, ribbon or toner. Our UK stock range is built for busy ecommerce sellers, warehouses and fulfilment teams, with the most searched sizes first: 4x6 (100x150mm) shipping label rolls and 4x4 direct thermal labels for courier despatch, plus smaller sizes like 4x2, 3x2 and 3x1.5 for product labelling, shelf labels and stock control.

These rolls are widely used for Royal Mail and DPD shipping, as well as eBay, Amazon, Etsy and other platforms that support the standard 100x150mm format. Choose white thermal labels for clean, sharp barcode printing, or use coloured thermal labels (blue, red, yellow, orange) to colour-code picking waves, returns and routing.

All labels are direct thermal with a strong hot-melt adhesive that bonds well to cardboard, film and most plastics. Compatible with popular 4” printers such as Zebra GK420 / ZD, Citizen CL-S and TSC DA/TE. Bulk packs are available for trade buyers, with same-day despatch before 5pm (Mon–Fri), VAT invoices included, and best-selling 4x6 rolls from £4.99 each (Inc VAT).

These formats are commonly used by UK sellers printing Royal Mail, eBay, Amazon and other courier labels in a 4×6″ layout.

How to Pick the Right Size

Courier labels – choose 4×6″ (100×150 mm)
Barcodes/SKUs – 4×2″, 3×2″ or 3×1.5″ depending on text length
Colour-coding – pick a colour that fits your wave or area code

Sustainability

Direct thermal labels reduce consumables by removing ribbons and toner. Choose fanfold or coreless to cut plastic waste. Recycle label cores and cartons where facilities exist.

Frequently Asked Questions

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

Do these labels work with Royal Mail Click & Drop and DPD labels?

Yes. 4x6 (100x150mm) is the standard format used for most courier shipping labels, including Royal Mail Click & Drop and DPD. As long as your printer supports 4-inch wide direct thermal rolls, they will print clearly.

Do these labels work with Shopify, eBay and Amazon shipping labels?

Yes. These 4x6 (100x150mm) direct thermal labels are widely used for shipping labels generated through Shopify, eBay and Amazon. As long as your label printer supports 4-inch wide direct thermal rolls, they will print cleanly.

Are these 4x6 thermal labels compatible with Zebra printers?

Yes. These 4x6 (100x150mm) direct thermal labels work with most 4-inch Zebra printers including the Zebra GK420d and GK420t that support roll-fed media.

Will these labels work in Citizen and TSC printers?

Yes. These 4x6 direct thermal labels are widely used with Citizen CL-S series and TSC DA/TE printers. They suit most 4-inch direct thermal printers that accept 100mm wide label rolls.

Do I need ink, toner or ribbon for these labels?

No. These are direct thermal labels, so you do not need ink, toner or a ribbon. Just load the roll and print.

How many labels are on each roll?

Each roll contains 500 labels per roll (4x6 / 100x150mm), with a perforation between each label for faster packing and clean separation.

What is the label size in millimetres and what is the core size?

Each label is 4x6 inches (100x150mm). The roll core is 1 inch (25mm), which fits most desktop thermal label printers.

What adhesive do these 4x6 labels use?

They use a strong hot-melt permanent adhesive, designed to stick well to cardboard boxes, poly mailers, shrink wrap and most plastics used in parcel shipping.

Will these labels stick to poly mailers and plastic packaging?

Yes. The hot-melt adhesive is designed to bond well to common ecommerce packaging materials including poly mailers, shrink wrap, mailing bags and most plastics, as well as cardboard boxes.

Are they water-resistant or long lasting?

These labels are designed for short-term shipping use. Direct thermal paper is not waterproof and the print can fade with moisture, heat, friction or strong sunlight. For wet conditions, we recommend protecting the label with a clear pouch or over-label.
