FAQs

Do You Provide Free Delivery?
Yes, we do. You can get free delivery on all orders over £50.
What are 100mm x 150mm Thermal Labels used for?
100mm x 150mm Thermal Labels are primarily shipping & postage labels, parcel/barcode printing, e-commerce packing slips, and warehouse asset tags—in effect, the standard size for 4x6 shipping labels used by couriers and online sellers.
Will these 100×150 mm labels work in my printer?
They will work in the majority of label printers using direct-thermal that can accept 4-inch (or 100 mm or so) wide media - but never assume the printer takes the roll/fanfold format, core diameter, and label length (150 mm). Unless a printer can accept proprietary cartridges or labelwriter-style rolls, then it might not be compatible.
Do I need ink, toner or ribbon to print on 100×150 mm thermal labels?
No - direct-thermal 100 x 150 labels do not require ribbon, ink, or toner (the printer head heats the thermal coating of the label). By comparison, thermal-transfer labels need a ribbon. Direct thermal is used in instances where inkless printing is desired.
How long will a direct-thermal 100×150 mm print last? Is it waterproof?
Direct-thermal prints perform for a shorter term - years in regular indoor conditions, including months (usually 12–24 months)—and they are more susceptible to heat, sunlight, oil or abrasion. Most are not typically waterproof unless they are printed on a specially coated or synthetic label stock (thermal transfer polyester/BOPP types are more durable).
What sizes/cores/pack counts do 100×150 mm labels come in?
Roll format (various core diameters: e.g., 25 mm / 1 inch, 38 mm, 76 mm) or fanfold stacks are common constructions, and typical commercial packs are 500 labels/roll/pack (though you also have 1000/2000 rolls of high volume). Always check the core size and labels per roll prior to ordering.
How should I store 100×150 mm direct-thermal labels to maximize life and print quality?
Keep in a cool, dry, dark place (a temperature of about 18–24°C / 65–75°F and 40–55% RH is suggested). Protect against heat and direct sunlight, solvents, and pressure to the printed surface - under good storage conditions unused labels retain optimum performance for up to 12-24 months depending on material.
