Check the specifications of any adhesive with a test batch as the glues can vary considerably. The descriptions may not be misleading to those in the industry, but may be to an 'outsider'. For example, you can get a 'semi permanent label' that may seem to fit the bill at first glance, but what it means is that you can move the label around within the first couple of days, and then as the glue cures, it becomes permanent. Different manufacturers sometimes use differing terminology.
The tamper label should have a permanent glue, otherwise the tamper evidence can be defeated negating the point of putting one on in the first place.
I have dealt with the labelling at my works for over ten years and it causes no end of headaches. I have access to professional labelling machines to create my own, but I will be buying on-line from an established supplier for now.
It is finding a label of the correct size which I find is the problem. Thornes labels for 1 lb jars are 80mm wide by 51 mm deep with round corners. I can't find any of the normal label suppliers who sell anything like this size. Has anyone found a suitable supplier?
Amazingly, I also found the same company this morning and they are sending me a sample too! They do a 75 * 50 label which would be fine for one pound jars, the Thornes ones are 80 * 51, and a 63 * 46 which is exactly the same size as the Thornes half pound labels. Both have round corners and are available in high gloss white as well as various other finshes. The high gloss only works on laser printers but should make a better label. As has been pointed out before, poor quality labels will be a bad investment if you are planning to sell your honey.
