Three sources of moisture in desiccant packaging

Three sources of moisture in desiccant packaging 

Desiccant has three sources of moisture in a specific packaging, and its mission is to absorb these three parts of water vapor and control the humidity inside the packaging below the target humidity.

1. The initial moisture contained in the air inside the product packaging. For example, the volume of product packaging is 1 cubic meter, and the initial temperature and humidity during packaging are 23 ℃. When the relative humidity is 85, the air contains 17.47 grams of water.

The moisture contained in the packaging materials inside the product packaging will gradually evaporate during storage and transportation. For example, wood usually has a moisture content of 15-30.

During storage and transportation, desiccants prevent moisture from penetrating into the product packaging by blocking the packaging material. For example, a barrier PE bag with a water vapor transmission rate of 2 grams per square meter per day and an area of 6 square meters will permeate 1080 grams of water into the packaging after 90 days.
