Paper has properties that are various donate to its performance, the most known of that are pH level, power, opacity and whiteness.
Alkalinity and acidity are calculated for a scale referred to as pH scale. Papers with a level that is high of have a tendency to decline quickly. Simply because the acids when you look at the paper attack the cellulose fibres and damage their structure. This sort of deterioration causes paper in order to become really discoloured and brittle.
