Cardboard is a generic term used for heavy duty papers of different widths that ranges from simple arrangements of a single thick sheet of paper to complex configurations that ranges from correlated layer to multiple corrugated layer. The cardboards are used as a basic material for manufacturing different packaging containers of different shape and sizes to stack multiple numbers of products in a single container. The cardboards are designed with two layer of paper along with singly ply fluted sheet and multiple layer of board with 3-ply, 5-ply and 7-ply fluted sheets. With an extensive usage of cardboards, it is necessary for the manufactures to strengthen the quality of the cardboards by testing and measuring the properties of the cardboards using highly sophisticated testing machines.
