Every dealer packaging alcohol for industrial use must affix to each package filled a label bearing in conspicuous print the words ``Alcohol'' and ``For Industrial Use,'' the proof of the alcohol, the capacity of the container, and the packaging dealer's name and address. The dealer may incorporate in the label other appropriate statements; however, such statements must not obscure or contradict the data required by this section to be shown on such labels.
