摘要： A container body component for forming a hermetically sealed paperboard container, the container body component being formed from a blank and including an upper end and a lower end and, the blank comprising: a) paperboard having a first side and a second side, b) a first sealant layer on the first side of the paperboard, c) a barrier layer on the second side of the paperboard, and d) a second sealant layer applied over the barrier layer, i) the blank having a first and a second longitudinal ends, the first end being skived to a predetermined thickness for a predetermined width, the skived portion being folded over onto the blank to form a folded first longitudinal end, the body component having an overlapped seam with the folded first longitudinal end of the blank inside the second longitudinal end; and ii) a bottom component sealed to the lower end of the body component; characterised in that the folded over skived portion is sealed to form an edge.
