Secondary Bake
We can supply irreversible thermochromic inks for printing onto packaging and wrap, which will change colour or reveal a message when cooked to a required temperature i.e. Where part baked products (such as bread rolls) are delivered to the store and given a second baking in the store, producing a hot freshly baked product. The printed packaging changes colour after the secondary baking process. This ensures that only fully cooked products are served or displayed for consumers.
