Papers and boards
Papers and boards are formed from wood pulp, which comes from trees. This squishy wood pulp is rolled out into thin sheets in paper mill factories to form the papers and boards that we use.
Paper
Papers are made from wood pulpWood fibres processed and reduced down with chemicals or mechanically broken down into smaller parts to make paper.. Their densityCompactness of a material. is measured by their weight, in grams per square metre (gsm) - the thinner the paper the lower the gsm.
Paper | Physical properties | Working properties |
Cartridge paper - used for drawing | Thick, textured, rough | Expensive and opaque, used for ink and watercolour |
Tracing paper - used for developing ideas, to trace ideas from one sheet to another | Translucent (see-through), smooth | Shiny, takes pencil well |
Copier paper - used for inkjet and laser printers to print from a computer | Thin, lightweight, bleached paper | Takes colour well, readily available, can jam printer mechanisms |

Board
Board thickness is measured in microns or grams per square metre (gsm) - the thinner the card the lower the microns or gsm.
Board | Physical properties | Working properties |
Corrugated card - used for packaging electrical products (absorbs impact) or hot food (good insulator) | Paper bonded to the outside | Corrugations make it strong, protective and insulating |
Solid white board - used for model making, packaging, cosmetic products | Smooth on both sides | Stiff, can be cut or scored |
Folding box board - used for packaging food products, eg cereal boxes | Made of three layers - a printable top surface, an unbleached centre layer and a bleached inside layer | Good for scoring without splitting, accepts print well, not as strong as solid white board. |
