Moisture damage of products

Damp damage

There are many forms of moisture damage, which will affect all types of products. When the goods are exposed to wet environment for a period of time (not necessarily for a long time), it may be damaged in many ways. Usually, even a small amount of excessive water can cause devastating damage, resulting in goods that cannot be sold, are not suitable for customer consumption or are not suitable for subsequent manufacturing processes.




The most common types of moisture-related damage are:

corrode

Moldy or moldy

Packaging damage

Packaging collapse

Bad smell or change.

Odor or bad taste

Label shedding

Powder caking

bred worms

Metal parts are sensitive to corrosion and rust, which will weaken the strength of metal or lead to discoloration. Corroded metal needs special and time-consuming treatment after transportation to restore its original characteristics. Relative humidity accurately describes how much water exists in the air at a specific temperature. The more water, the faster the metal rusts. For example, it is difficult for any corrosion to occur in clean air with a relative humidity of 45% or less. If the relative humidity increases to about 60%, the risk of corrosion will also increase. With the increase of relative humidity, the degree of corrosion problems and rust increases exponentially.


Mold and mildew can affect organic goods, especially food and agricultural products, and also cause terrible pests or odor. When the relative humidity is above 75% (but research shows that problems may occur when the relative humidity is low, such as 50%) and the temperature is between-5 C and+55 C (the optimum temperature for mold and mildew is 20-30 °C), mold is easier to grow, and this is inevitable in many cases, because it is impossible to protect the goods from mold during storage or handling. Therefore, the simplest way to protect goods from mold is to reduce the moisture content.


Excessive moisture will also cause irreversible damage to the packaging of goods, and may eventually collapse, because the packaging is hygroscopic and will absorb moisture. Excessive moisture may also be the cause of label peeling on glass bottles or food cans.


In dry goods such as powder, moisture damage is manifested as caking. This is because dry powder is usually hygroscopic and absorbs moisture.


Being wet poses a threat to the quality of your goods and may lead to expensive costs.
