Our labels are suitable for any number of purposes including food packaging. We have applied our labels to coffee bags, tea leaves, protein powders and pet food. There's obvious limitations to the lifespan and performance of the labels, if the paper labels get wet, they're going to get soggy and tear more easily, where as PET ones will last longer in the same conditions. Similar logic applies to labels that will be exposed to extreme or long period of light and sun exposure. We don't recommend attaching you labels directly onto your product without any packaging, it's certainly not going to taste any good!.
