Four types of combined board for corrugated

Combined_Board_rgbCombined Board

The below illustration demonstrates four basic types of combined board that are most commonly created from linerboard and medium using the variety of flute structures:

  • Single Face:One corrugated medium is glued to one flat sheet of linerboard.
  • Single Wall:The corrugated medium is glued between two sheets of linerboard. Also known as Double Face.
  • Double Wall:Three sheets of linerboard with two mediums in between.
  • Triple Wall:Four sheets of linerboard with three mediums in between.

Generally, larger flute profiles deliver greater cushioning and vertical compression strength, while smaller flute profiles provide enhanced graphics capabilities. Smaller flutes such as E and F also provide enhanced structural capabilities for primary (retail) packaging compared to paperboard (folding cartons). There is a good deal of variance across the industry in the range of flute sizes based upon the container characteristics that are desired for each application, as well.
