A composite panel 60 is formed by aligning a first blank 10 with a second blank 40 in a substantially coplanar back-to-back arrangement. The blanks 10, 40 are arranged such that the composite panel comprises two non-overlapping marginal regions 62, 64. The composite panel 60 is curved about an appropriate former to bring the first non-overlapping region 62 into overlap with the second non-overlapping region 64 and the two non-overlapping regions 62, 64 are then glued together. Prior to the formation of the composite panel 60 the first 10 and second 40 blanks are provided with appropriate finishes such that when folded into a tubular shape the finished face of the first blank 10 forms the external face of the tubular packaging container and the finished face of the second blank 40 forms the internal face of the tubular packaging container. A closure means is then fixed to one of the open ends of the tubular body to form the base of the resulting tubular packaging container. A further closure means is fixed to the other open end of the tubular body to complete the tubular packaging container. |
