Products are transported from the place of manufacture to end user in carriages. These packages are to protect the good from environmental conditions. The boxes may absorb some moisture from atmosphere that can even affect the good packed within it. Every paper and packaging material have hygroscopic property that is the property of holding water molecules from the surrounding environment.
The moisture holding property of corrugated boxes need to be checked before packing any type of product like food eateries, oil packets or machinery in them. This property can be measured with the Cobb value. Cobb value is defined as the property of paper or packaging sample of 1 m² of absorbing water in recorded time under specific conditions. If Cobb value is high, the absorption capacity is high and with low Cobb value absorption capability is low.
