The present invention provides a method for producing a low-odor, printed
packaging material and the printed packaging material produced thereby.
The printed packaging material of the present invention is especially
suitable for packaging of substances, such as food, drugs and tobacco,
which require low odor from printing inks. In this process, the printed
ink is activated by exposure to actinic radiation, such as UV light,
before an actinic-radiation curable coating is applied thereto. The
exposure of the printed ink to UV light reduces residual solvent content
and odor of the packaging material and improves the friction resistance
and gloss of the printed images. Furthermore, the exposure of the printed
packaging material to UV light provides an additional benefit of reducing
microbial count, thereby extending a shelf-life of the packaged
substance, such as food and drugs.
