Abstract:
A shielded packaging system formed by securing to one another a pair of abutting panels about their respective peripheries, wherein each panel comprises:a first layer of plastic; a first layer of lead foil; a first layer of adhesive disposed between said first layer of plastic and said first layer of lead foil; a second layer of lead foil; a second layer of adhesive disposed between said first layer of lead foil and said second layer of lead foil; a second layer of plastic; a third layer of adhesive disposed between said second layer of lead foil and said second layer of plastic; said layers collectively positioned in a common, substantially flat plane; and said panels being joined to one another about a predetermined extent of their respective peripheral edges; an opening defined where said respective peripheral edges are not joined to one another; each panel of said shielded packaging system including said first and second layers of lead foil so that if a pinhole is formed in said first layer of lead foil it will not be in alignment with a pinhole that is formed in said second layer of lead foil, other than by pure chance.
