Abstract:
A method for determining if a chemical additive used in the manufacture of paper packaging will contain a chemical component or reaction product that is of toxicological concern to a consumer of said paper packaging as a result of the addition of said chemical additive to a manufacturing process to manufacture paper packaging, wherein said method comprises the steps of:(1) cataloging a plurality of chemical additives which will be added to a paper packaging manufacturing process and amounts of said chemical additives which are originally desired to be added;(2) determining an actual concentration of said chemical component and reaction product in said chemical additives which will be added to said paper packaging manufacturing process;(3) calculating a toxicologically allowable concentration of said chemical component and said reaction product in said paper packaging which will be produced by said paper packaging manufacturing process;(4) comparing said toxicologically allowable concentration with said actual concentration;(5) identifying, if any, chemical component and reaction product and their actual concentrations which are greater than said toxicologically allowable concentration; and(6) adjusting, if necessary, said actual concentration such that said actual concentration is no greater than said allowable concentration, wherein for differences between said allowable and said actual concentration which are less than 10% of the allowable concentration, said method further comprises the step of:(7) contacting any supplier of said chemical additive which will be added to said paper packaging manufacturing process which will produce said chemical component or reaction product that will have an actual concentration greater than said allowable concentration,(8) recalculating said actual concentration of said chemical component or reaction product that have an actual concentration greater than said toxicologically allowable concentration, and(9) employing a qualified toxicological analyst to review said actual concentration, said allowable concentration, and said comparison between said actual and allowable concentrations, to determine if such a difference between said actual and allowable concentrations warrants a toxicological concern to a consumer of said paper packaging.
