ABSTRACT:
A plastic can is formed of a body member including a content protecting layer which is a tubular body formed by folding back and outward one side edge of a laminated film, bonding the folded parts such that air bubbles are not entrapped thereunder, overlapping the other side edge of the same laminated film on the bonded surface and bonding the side edges such that air bubbles are not entrapped between the side edges. An additional sheet is bonded all over the external surface of the laminated film except for a projecting stripe formed by the bonding of the side edges. A surfacing plastic layer covers the additional sheet and the projecting stripes. An apparatus is provided for forming the can, smoothing the surfacing plastic layer, forming the tube into can bodies, shaping the can bodies and sealing, lids on the ends of the cans.
