Raw materials
1. Wood
2. Bleach
3. Chalk (fillers)
4. Starch (sizing makes the paper resistant to water-based ink i.e. inks sit on top of a sheet of paper, rather than sinking in)
Process
Wood to pulp to paper
Pulp fed into paper-making machines where a paper web is formed on an endless wire screen. The screen passes through presses and over dryers to the calenders and reels.

Paper - among others, an important medium to record down knowledge of infinite varieties; a most demanded material you've created today!
ReplyDeleteSome day would like to see the actual process of production especially at what stages of processing bleach, chalk, and starch are added into the process.
For packaging, it must be a different kind of paper that is used - the cardboard.
All these raw materials can be found in Aussie. What Aussie trees are used to make paper, I wonder?
One that I know of is the Eucalyptus tree. There are more than 700 species of Eucalyptus, mostly native to Australia. Eucalyptus is the most common short fibre source for pulpwood to make pulp. Eucalyptus globulus and Eucalyptus grandis are the most used varieties in paper-making.
ReplyDeleteYes, most definitely right. There are different paper types in packaging like asphalt paper and parchment paper. However, "normal" paper still could be use for packaging for example, I've used paper to wrap my stationary (erasers in particular) when moving houses.
Most amazing those Eucalyptus are! Not only food for koalas but also for paper making. I think, here in Malaysia, people use Acacias such as Acacia mangium and Acacia auriculiformis for paper making. Acacias are soft wood. They are also native to Australia; meaning Acacias grown in Malaysia originated from Australia.
