I have made several batches of jam over this summer and would like to label the jars.
I am printing the labels on my laser printer for a more professional look. Also, I want to reuse the jars, so getting the labels off again is a requirement. This rules out the usual sticker-type paper labels, as they are a pain to get off.
Until a few years ago, paper labels with some kind of water-soluble adhesive were the norm on store-bought jam (and other) jars in Europe (but are now increasingly being replaced by those pesky self-adhesive labels), and one approach I looked into was to replicate that.
Some folks out on the net have suggested gelatin: mix ground gelatin with water (1:1 by weight), heat it and apply it to the back of the label, then place it on the jar. I have tried that, and while it initially sticks well, most labels come off again once they dry.
Another option might be self-stick labels made of plastic rather than paper, which are less prone to tearing and can thus mostly be peeled off in one piece. However, they would need to be laser-printable, i.e. resist the usual temperatures found in the process and come in a size I would be able to feed into the printer.
A cheap hack would be to print the labels on regular office paper, and attach them with transparent tape, but that ends up looking cheap.
Has anyone found a feasible way to attach labels to jars so they can be peeled off easily, or come off in the dishwasher?*
*) While some self-stick labels do come off in the dishwasher, the adhesive gets into everything and is impossible to get rid off, ruining your dishwasher in the long run. I’m speaking from my own experience.
