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.
