The packaging boxes and paper are processed products from trees. The process of producing paper boxes and paper usually follow this process.
Paper Making Process
Paper Making Process

  1. Trees are cut down for wood - Trees may come from plantation forests of native forests. Trees can be either hardwoods, like eucalyptus trees, or soft woods, like pine trees
  2. Wood is debarked and turned into wood chips
  3. Wood is turned into pulp which is further cleaned and refined. Pulp is made from woodchips which are made by breaking up the left over wood that can’t be used to make furniture or homes. There are two ways to make pulp from wood: (1) mechanically - the wood chips are crushed with water by rotating grindstones that physically tear the fibres apart. This process is used to make pulp for less strong paper products such as newsprint; (2) chemically – the wood chips are cooked under pressure in a digester with water and chemicals (e.g. sodium sulphite) which dissolve the material holding the fibres together. This used when you need strong paper.
  4. Pulp is pumped onto a moving wire screen and squeezed between rollers to remove water. Paper is made in large factories called paper mills. In order to make paper, the wood pulp is washed, cleaned and sometimes it is bleached to make it white in colour. A beating machine turns the clean pulp into pulp slush which is pumped onto a moving wire screen. As the pulp travels down the screen, water is drained away and recycled. The resulting crude paper sheet is squeezed between large rollers to remove most of the remaining water and ensure the paper is smooth. The semi-dry paper is then run through heated dryer rollers to remove the remaining water.
  5. Dry paper is wound onto rollers and cut into sheets for use. The finished paper is then wound into large rolls, which can be 10 meters wide. A slitter cuts the paper into smaller, more manageable rolls, and the paper is ready for use.
