Nowadays, it is not possible to produce food packaging without the use of polygraphic varnishes. Their main task is to protect packaging from the effects of external factors, as well as to give the effect of clarity with greater exposure of the colors used. However, such varnishes contain in their composition low-molecular-weight photoinitiators that can easily migrate to a protected product. The aim of this work was to determine the migration of 4-PBZ from various types of substrates used in the printing industry, i.e. paper, aluminum foil and polyethylene foil. In addition, extensive studies on the impact of the storage conditions of a fresh reprint on the change in the migration of the photoinitiator to food were carried out.
