What is Moisture Absorber?

Moisture absorbers are products capable of extracting water vapor from the air, thus helping to prevent condensation forming on containerized cargo packaged materials.

Considered a desiccant, drop-in pouches regulate moisture and sustain dryness. They are designed to absorb condensation or "cargo sweat" inside international oceanic shipping containers and secondary packaging to prolong, protect and preserve supplies or delicate items along the supply chain.

Typically, heat sealed, pouches are filled with a proprietary blend of non-toxic moisture absorbing granules that induces or sustains a state of dryness in any environment inside its sealed vicinity.

Moisture Absorbers – How They Work

The factors that determine the rate of absorption are temperature and humidity
A solidified mass is part of the absorption process and not a product fault and indicates that the beads are absorbing excess moisture
The beads will dissolve at a slower rate when there is less excess moisture in the air
When there is eventually enough excess moisture in the air the beads will dissolve and the solidified mass will turn to water.

Types of Moisture Absorbers

Silica Gel

Silica Gel is a moisture absorber made from sodium silicate. It has a high specific surface area which makes it a very powerful desiccant or drying agent. Its name may be misleading because this form of silica is actually solid, produced in a beaded or granular form.

Clay Absorbers

Clay absorbers offer a cheap alternative to absorbing moisture in a home or in any other space where moisture leads to molds. Its moisture absorption property is very low as compared to the other two types. For heavily humid areas, clay absorbers are not recommended.

Calcium Chloride

Perhaps the best moisture combatant is calcium chloride, a mixture of chlorine and calcium. Calcium chloride is usually used in shipping goods and does a good job in keeping these goods dry during the whole duration of the trip. For very humid basements, kitchens, cabinets, closets, and other spaces, calcium chloride does provide effective moisture absorption.

Helpful Hints
●If you need to store or protect items beyond the 60-day threshold, simply add a few more bags to the treated area!
●Our desiccants are air activated and it's very important to keep any unused desiccants air tight. A moisture barrier or vacuum seal bag is preferred.
●To insure peak protection, if possible check pouches during hot, humid weather or when temperatures are regularly fluctuating.

How to Choose Moisture Absorber

Size and Capacity

First, consider the size and capacity of the desiccant bag. A larger bag will be able to absorb more moisture, ensuring that your books and belongings stay dry and well-preserved.

Moisture Absorption Efficiency

Some desiccants can absorb more moisture than others. A high-quality desiccant will effectively remove excess humidity from your storage space, preventing mold, mildew, and other moisture-related issues.

Reusability and Lifespan

Some desiccants can be reactivated, allowing for multiple uses before needing to replace them. Reusable desiccants are more cost-effective, environmentally friendly, and practical than single-use ones.

Safety and Eco-friendliness

Ensure that the product you're considering is non-toxic and safe for use around people and pets. Additionally, look for eco-friendly options made from natural or sustainable materials to reduce your environmental impact.

Indicator Features

Some desiccant bags come with moisture indicators. These indicators notify you when the bag has reached its moisture absorption capacity and needs to be replaced.

Certificate

We had passed the ISO9001:2015, ISO14001:2015, BSCI, GMP and Walmart audits. Our products comply with RoHS certification and other certificates.

Common Problems

Q: What is moisture absorber used for?

A: A moisture absorber will help to reduce the excess moisture, thus making the air more pleasant to breathe. Another benefit of a moisture absorber is that they help protect your belongings against the effects of moisture.

Q: Should I use moisture absorber?

A: It is recommended to use a moisture absorber when experiencing effects of excess moisture in the home, including condensation, black mould and mildew, as well as peeling, cracking, or blistering on interior surfaces.

Q: Is a moisture absorber the same as a dehumidifier?

A: Damp crystals are not a substitute for an electronic dehumidifier. They are definitely not as effective and are not a long-term solution for a damp issue.

Q: What is moisture absorber in food?

A: Moisture absorber regulates water activity of the product to suppress the microbial growth (Choi and Lee 2013). The common form of moisture absorbers is sachets, films, tray and pads which usually employed to maintain fluid exudates from food products or to maintain the relative humidity inside the package.

Q: Where do you put moisture absorber?

A: Remember, the key is prevention and avoiding high levels of moisture. You already know how to help with that: with a moisture absorber. Place it in those rooms where there are high levels of moisture, such as bathrooms or kitchens. And do not forget to ventilate your home.

Q: What is the best thing to absorb moisture?

A: If solving your moisture problem is something you'd like to do inexpensively, rock salt may be your answer. Because rock salt is hygroscopic it absorbs moisture from the air. If your plan is to get rid of the humidity in a damp basement, start with a 50-pound bag of sodium chloride to make your rock salt dehumidifier.

Q: How long do moisture absorbers last?

A: Think of it as a dehumidifier without electricity. Each moisture absorbing bag lasts up to 60 days depending on temperature and humidity.

Q: Do moisture absorbers stop mold?

A: Chunwang Fragrance-Free Hanging Moisture Absorber attracts and traps excess moisture from the air, eliminating musty odors and inhibiting mold and mildew. Chunwang crystals absorb excess moisture out of the air to create optimal humidity.

Q: How many moisture absorbers do I need?

A: The general rule is that a minimum of 1.2 units of desiccant per 1 cubic foot of volume is needed to adequately protect a given space. For more information about desiccants, AGM's "Selecting the Right Desiccant" has you covered.

Q: What is an example of a moisture absorber?

A: Desiccants or moisture absorbers are commonly composed of hygroscopic substances such as silica gel, MMT or bentonite clays, and calcium oxide are used for dry or moisture-sensitive foods in the form of pads, sachets, and films as moisture barrier agents.

Q: How often do you need to replace moisture absorber?

A: The lifespan of the absorber varies depending on the humidity in the room. As a rough guide, it will take approximately 2 months for a 40/50 m3 room.

Q: What is moisture absorber made of?

A: It consists of a non-toxic inorganic mineral salt called calcium chloride that naturally absorbs moisture from the air.

Q: Do moisture absorbers remove smell?

A: This unique moisture absorber with activated charcoal doesn't just cover up musty odors, it absorbs excess moisture and removes odors from the toughest sources. No more stale, stagnant, musty smells! Best for use in spaces where airflow is limited and excess moisture is a problem, like bathrooms and closets.

Q: Do room moisture absorbers work?

A: Yes. We put a container in a sealed test chamber about the size of a closet with 80% humidity and a fan for air movement. Within three days, reduced humidity to 43% and collected almost half a cup of water.

Q: How do you refresh a moisture absorber?

A: You can do so by pouring the inactive silica gel beads in a thin layer on a baking sheet. You should then preheat the oven to 175 degrees Fahrenheit and bake the beads for 15 minutes. The heat in the oven will draw the moisture out from the desiccant material and reactivate the drying agent.

Q: Can you put moisture absorber in bathroom?

A: Bathrooms are humid places and to get rid of excess moisture you will have to air out the room. This can be achieved by simply opening a window or by using a CMV system, a moisture absorber or a dehumidifier.

Q: What is the process of moisture absorption?

A: Deliquescence, the process by which a substance absorbs moisture from the atmosphere until it dissolves in the absorbed water and forms a solution. Deliquescence occurs when the vapour pressure of the solution that is formed is less than the partial pressure of water vapour in the air.

Q: What is the chemical for absorbing moisture?

A: Calcium chloride is highly effective, and one of the most hygroscopic materials, when it comes to absorbing moisture from the surrounding air. Calcium chloride is an inorganic compound – a salt with the chemical formula CaCl2.

Q: What is the purpose of a moisture absorber?

Q: How do I know when to replace my moisture absorber?

A: Your moisture absorber needs to be replaced once it is completely changed to a honey colour gel. The lifespan of the absorber varies depending on the humidity in the room. As a rough guide, it will take approximately 2 months for a 40/50 m3 room.
