Removable Labels
There are a number of label options on the market claiming to be removable, but most are just standard labels with a low grade adhesive.
These can be easily removed in the short term, the longer the label stays applied to the surface the harder the adhesive will become. These labels tend to be inexpensive, but will leave a sticky residue behind when removed.
If you require a true removable label, then the only option is a Prime Cote Removable. This label when removed will take the majority if not all of its adhesive with it.
