Abstract
A ballistic panel is described that comprises a ballistic-resistant component and a cover that comprises a laminate comprising (i) a substrate layer and (ii) an inner bonding layer. The cover is bonded to at least one surface of the ballistic-resistant component by the inner bonding layer of the laminate, and is bonded around the perimeter of the ballistic resistant component to form a perimeter seal. A method for making the ballistic panel is also described.
