1. The answer to this question is simple. Good desiccant bags, used in storage and shipping containers, or other vessels, should: 

    (a) Not leak and 

    (b) Absorb moisture as expected

    To ensure they perform as intended, rigorous testing is required – which is something we happen to do very well and frequently.

    Here’s How We Test Our Desiccant Bags and Other Desiccants

    We perform the following tests to ensure our desiccant bags and other desiccants do not leak when subjected to excessive movement and severe pressure:


    1. Hydrostatic Pressure Test – on our StoGel and StoDri Products
      To determine resistance to pressure from water. 


    In addition to testing for leaks by applying significant water pressure, this test assesses structural integrity and verifies performance should the product experience similar pressure.


    1. Tensile Strength Test – on our StoGel and StoDri Products
      To measure seal strength of the bag.


    Also known as tension testing, this fundamental materials science and engineering test is used to subject a product or part of a product to a controlled tension to ensure it can withstand likely pressures it may experience during use.


    1. Tear Propagation Resistance Test – on the Membrane of Desiccant Material
      To measure the resistance of material tearing.

    This test helps determine the force that is required to tear a sample material. This information is then used to ensure the material is optimised to withstand circumstances that may lead to such tearing.


    We perform the following tests to ensure our desiccant bags and other desiccants absorb moisture according to their claimed performance:


    1. Moisture Content Test – on Clay Raw Material
      To ensure that starting materials are dry.



    2. Calcium Chloride Purity Test – on Calcium Chloride Raw Material
      To ensure the starting materials are of required quality.


    Moisture and condensation caused by inevitable temperature fluctuations experienced during transit can wreak havoc on the contents of containers. To ensure our products can withstand the circumstances, conditions are replicated to test their performance.  


    In addition to the above, the following tests are also carried out:


    1. Humidity Chamber Test – on All Our Desiccant Products
      To determine how well the desiccant performs under circumstances / in the market.
    2. Independent Verification with Intertek – on All Our Desiccant Products
      To validate results and foster trust in our data.

    It is evident that these tests are extremely valuable in that they meet and often exceed expectations and therefore confirm their effectiveness and reliability for their intended applications.
