Paper printing, packaging and storage


Paper and cardboard – in all their myriad forms – easily absorb moisture from the surrounding air. This can cause varying degrees of damage, which affects the usefulness and value of these products.

Frequent problems include:

  • Brittle paper-based products
  • Changes in the shape, appearance and functional integrity of paper and cardboard products
  • Increased waste and write-offs
  • Mould and other bacterial growths that affect product value and appearance

Humidity challenges in paper, printing and packaging storage

In paper and cardboard manufacturing, both the materials used and the end products are hygroscopic. They readily absorb moisture from the surrounding air, which always contains fluctuating levels of uncontrolled moisture – not least due to climate and weather conditions.

For companies engaged in either manufacturing or storing (or both) paper and cardboard – in whichever of their many forms – uncontrolled levels of airborne moisture bring many perils with big impacts on product and inventory value.

The same applies to places where packaging made from these moisture-absorbent materials is used – our world is increasingly based on vast logistics networks in which almost all goods are packaged for protection and cost-effective transport. Damage to the packaging usually means the contents are written off – a colossal source of value loss.

When paper-based products absorb such moisture, they often change shape, their appearance is affected and they lose their functional integrity – causing values to plummet. Excess humidity – especially during storage – can also easily give rise to mould and other bacterial growths that can spoil paper products and render them unsellable.

On the other hand, if the relative humidity of the surrounding air is too low, paper-based products tend to lose their strength and become brittle. Which also impacts their value.


Preventing product deterioration and value loss

The most effective way to tackle humidity-related problems and their costly impacts in such facilities – and their costly impacts – is to remove the large amounts of airborne moisture that may be present.

Using exceptionally small amounts of energy, Cotes adsorption dehumidifiers make it possible to roll back the moisture load in any storage facility for moisture-absorbent paper products and packaging, and to protect paper-based products of all kinds from absorbing moisture from the air, thus incurring value-impacting damage.

Lower levels of humidity within a building also bring additional side benefits by preventing corrosion in equipment and structures, as well as helping avoid moisture-related glitches in electronics and electrical equipment.


How you benefit

  • Maintain better control of air conditions anywhere you store paper, cardboard and packaging – or goods packaged in such materials
  • Maintain product value, reducing waste, damage and write-offs
  • Prevent corrosion and other humidity-related damage to structures, fittings and equipment, resulting in lower building maintenance costs
  • Minimise energy consumption while doing so, by using unique Cotes heat recovery modules
