Classification of packaging board

Single Face Cardboard – the most economical cardboard to buy, it is thinner than other cardboard but offers more protection than paperboard.Single Wall Cardboard – this cardboard has a flute between two layers of paper, making this cardboard more durable than single face.   Flutes gauges range from F to A, with A being the thickest and F offering the least thickness and hence the least protection from impact.Double Wall Cardboard – this cardboard offers better impact protection due to its two layers.Triple Wall Cardboard – this cardboard is so strong that it often is used in place of wood crates.   It is used in heavy industrialAll corrugated fiberboard products can be baled by different cardboard balers, but they will require different gauge wires.   If the same number of cardboard sheets were baled into equal volumes, single face cardboard would put the least pressure on the baling wire hence this requires a higher gauge.   Whereas triple wall cardboard would put the most pressure on the baling wire and would require a thick gauge like 10 or 11.
