Dissolvable Laser Printer Labels

Label, rinse, repeat. These labels disappear after 30 seconds of contact with water, leaving no residue. Use them to temporarily tag containers that you wash often, such as beakers and flasks. They’re steam resistant, so they won’t dissolve in an autoclave. These labels are FDA compliant for indirect contact with food. Run them through any standard laser printer.
