Abstract
Individual carton blanks formed from a lamination of a continuous strip of a relatively rigid material and a relatively flexible fluid impervious material and in some instances from spaced apart continuous strips of a relatively flexible material wherein all of the cut and fold lines are formed in the continuous strip of a relatively rigid material and then conveyed to the nip between two rotating laminating rolls where all of the continuous strips are secured together by an adhesive at desired locations. In some instances, the continuous strip of a relatively flexible fluid impervious material and the spaced apart continuous strips of a relatively flexible material are cut at a location spaced from the leading edge of the individual carton blanks.
