These have been tried and tested in our warehouse, and they can, but they lose a little of their stickiness.

Ideally, yes. You can write on these if you absolutely must, but they don't hold ink particularly well. If you're wanting some more exciting designs on your sticky package counterparts, try our Ecostickers or Customisable Ecolabels.

Not all postage labels are made equal (or sustainable), but our Ecolabels are! They're home and industrial compostable.

A direct thermal label is embedded with a heat sensitive material that gets darker when exposed to heat. Science.

Thermal labels are heat sensitive, so they'll slowly fade when exposed to direct sunlight or heat. But! Do not fear! Even after 3 months in the sun, they'll still scan. We use these shipping labels for all our parcels, and we've found we can still scan them after 6 months. They'd have to sunbathe for an absurd amount of time to be unreadable.

So the long and short of it is, if you're printing something like a barcode that won't be in direct sunlight, you can expect it to stay scannable for up to a year. Just maybe don't take the package to your sunny beach holiday in Majorca.

Nope, a TSC Thermal Printer needs to print onto the good ol' heat sensitive stuff.

Right here, in our sunburnt country.
