Papers and Boards

Papers and Boards

Papers

  • Papers are made from natural fibres, most commonly from wood pulp, which are processed into a slurry and then dried to form a flexible sheet.
  • They are characterised by their light weight, flexibility, and the ability to be printed upon.
  • Newsprint is a cheap, low-quality paper used primarily for newspaper production due to its absorbency and affordability.
  • Cartridge paper is a high-quality paper, heavier than newsprint and often used for drawing or painting as it can withstand erasing and heavy shading.
  • Layout paper is lightweight and semi-transparent, suitable for initial ideas and sketching.
  • Card and Board fall under this category too, but they are thicker and more rigid.

Boards

  • Boards are similar to paper but much thicker and stiffer. They are used for applications that require more strength and rigidity.
  • Corrugated board is commonly used for packaging applications due to its cushioning properties and resistance to impact and compression.
  • Solid whiteboard is used for high quality packaging and book covers due to its smooth finish and printability.
  • Duplex board has a different finish on each side and is often used for food packaging due to its resistance to moisture.
  • Foamboard has a foam core sandwiched between two paper layers, making it lightweight and useful for model making.

Working with Papers and Boards

  • Paper and board can undergo several converting processes to form final products including cutting, folding, creasing, gluing, and laminating.
  • Special techniques, like die cutting, embossing, and UV varnishing, can at times be used to alter the physical properties of paper and boards.
  • Printing methods, including screen printing, digital printing, and lithographic printing, are all used to add design elements on papers and boards.
  • When working with papers and boards, safety is less of a concern compared to working with metals or woods, but care should be taken to avoid cuts and paper-related injuries.

Environmental Considerations

  • Both paper and board are primarily created from trees, a renewable resource, but their manufacture can involve substantial energy consumption and waste generation.
  • Many types of paper and board are recyclable, leading to less waste. However, the recycling process itself can consume significant energy and water.
  • Increasingly, recycled paper and boards, as well as options including sustainable forest paper and board, are being used to lower environmental impact.
