Causes of oxidized spots on hot stamping paper
The oxidation of the bronzing paper after bronzing is mainly affected by the bronzing substrate. Generally, the substrate is too acid-base, and the bronzing paper is metal-plated aluminum layer. The reaction between aluminum and acid-base is relatively fast, so it is good after bronzing , After a period of time, it will discolor and oxidize to cause spots, and the higher the temperature, the more serious it will be. Let's take a look at the oxidation problem of bronzing paper after hot stamping.
