Abstract: A method for reducing the migration of aldehyde compounds present in packaging material the interior of a package formed by said packaging material, said method comprising: (a) selecting an initial packaging sheet stock used for forming a package having an interior in which an aldehyde sensitive product can be contained, wherein said initial packaging sheet stock has a first surface that forms the interior wall of said formed package, wherein said initial packaging sheet stock has a second surface that forms the exterior wall of said formed package, and wherein said initial packaging sheet stock contains one or more aldehyde compounds that are capable of migrating from said initial packaging sheet stock to said package interior or exterior; (b) preparing an amine-containing composition comprising an amine that chemically reacts with said aldehyde compounds to form a substantially non-migrating compound; and (c) applying said amine-containing composition onto said first surface of said initial packaging sheet
