Abstract
Abstract A metal can body is formed with a longitudinally extending lap side seam which is securely bonded with a nylon type high strength organic adhesive. In order to provide a strong permanent bond in the side seam, the body is precoated with an epoxy type coating which adheres tenaciously to both the adhesive and to the metallic body surfaces.
