Perforation is a smaller, easily overlooked spec compared to label size or adhesive type, but it's worth understanding what it actually does — and why it matters far less for shipping labels than for some other label uses.
What perforation actually does
A perforated label has a line of small cuts running across the join between one label and the next, similar to a perforated page in a notebook, making it possible to tear labels apart cleanly by hand without scissors or a printer's built-in cutter.
Die-cut labels vs. perforation — related but different
It's easy to conflate perforation with die-cutting, but they solve different problems. Die-cutting (covered in our continuous roll vs die-cut guide) defines where one label ends and the next begins for the printer's gap sensor. Perforation is about how easily a human can physically separate two labels by hand — a die-cut roll can be perforated or not, independently of the die-cut spec itself.
Hand-tearing vs. printer-cutting
Most desktop thermal printers used for shipping labels — the models covered in our printer buying guide — either auto-cut or have a built-in tear bar that separates labels cleanly regardless of perforation. This is why perforation matters less for shipping labels than you might expect: the printer is doing the separating, not a person tearing by hand.
When perforation matters more
Perforation earns its keep in manual, non-printer contexts — labels being hand-torn from a roll at a packing bench without a cutter, or dispensed from a desktop label holder rather than fed directly through a printer. If your workflow involves separating labels by hand at any point, perforated stock is worth specifically requesting.
What to check before buying
For standard printer-fed shipping label use, perforation is a nice-to-have rather than a requirement — prioritise die-cut accuracy, correct core size and consistent adhesive over perforation specifically. If you're comparing suppliers, our UK supplier guide covers the specs that matter more for reliable dispatch.
Clean separation, printer or by hand
Our rolls cut cleanly through any standard thermal printer's built-in cutter or tear bar — no fumbling between labels.
