Silica Gel - An Introduction
We all are familiar with Silica Gel in our day-to-day lives. They can mostly be seen in the packets containing our various purchases like electronic goods, leather items and food products. The main reason behind placing Silica Gel sachets along side packed products is to ensure that all the moisture present in the closed spaces will not damage the goods inside.
Silica Gel is usually available in beads, balls and granular format. The biggest plus point of using Silica Gel is that it acts as a desiccant and
controls the humidity levels in the atmosphere.
The Silica Gel desiccant can be classified into the following categories- Type A, Type B, and Type C. All these types are translucent and have multiple pores for better absorption. The three types have a wide range of uses like liquid
adsorbents, catalyst carrier and
drier among others.
The main use of Silica Gel, as mentioned above, is for effective removal of humidity
packages. For this
purpose, Silica Gel is often graded into different colors, depending on its
use. The most commonly used types are Silica Gel Blue, Silica Gel Orange,
Silica Gel White, and Silica Gel Green. The from colour change in these Indicating
Silica Gel is due to the presence of materials like cobalt chloride, which act
as the moisture indicators.
All these types of Silica Gel desiccant change color as they absorb moisture. This color change is a good indicator of how much moisture has been absorbed. It will also indicate when the Silica Gel desiccant is completely saturated and thus needs to be replaced. Placing a indicating Silica Gel (as they are known in the market) in packaging applications ensures that the moisture levels inside are maintained at optimum levels. The main advantage, if one is to opt for Indicating Silica Gels is that you will get to know instantly whether the Silica Gel is functioning properly or not. If one is using non-Indicating Silica Gel then it may be a long time before you get to know that the Silica Gel sachet has got saturated.
For the use of Silica Gel sachets to be proper, it is important to
wok with reliable Silica Gel traders.
Suppliers of Silica Gel Blue, green, orange and Pink must provide top-quality
desiccants to companies so that effective moisture control is ensured.
India is one of the highest rated quality Silica Gel supplier in the

What are Oxygen Absorbers?
Oxygen Absorbers are small sachets containing iron powder or ferrous oxide. They find great use across many industries, mainly food and beverages. The oxygen absorbers are manufactured in such a manner that it can absorb oxygen and moisture simultaneously but will not allow the iron powder or ferrous oxide to leak outside. The oxygen absorbers take in all the excess oxygen present in the packages containing food items, thus ensuring that proper oxygen levels are maintained. The presence of excess oxygen in food packages can spoil the food and make it inedible by the time it reaches its final destination. Another benefit of using oxygen absorbers is that it is not harmful for the packed food items as it does not react with the latter. It is for this reason that the oxygen absorbers are made available only in a sealed pouch.
How do Oxygen Absorbers Function?
Oxygen Absorbers function using a simple chemical reaction. When placed in an oxygen-rich atmosphere, they will absorb all the excess oxygen. The ferrous oxide/iron powder will react with the absorbed oxygen and turn into rust. This process will continue till all the iron powder has been oxidized. When it stops, we can say that the oxygen absorber is fully loaded and will not absorb any more oxygen. The oxygen absorbers can be used more than once as they can be regenerated by the simple process of heating.
How Oxygen Absorbers Preserve Food Items?
When oxygen absorbers are placed along side packed food items, they work to remove all traces of excess oxygen. After the oxygen is removed, the food items are in a nitrogen-filled atmosphere, which is ideal for the long shelf-life of the packed products. The oxygen absorber sachets are useful in preserving dry foods as well. It keeps them safe from insects and maintains their top-class product quality.
Placing an oxygen absorber sachet along side your packed food products will ensure that they are free from spoilage organisms like fungus, algae and molds. Oxygen absorbers also protect against aerobic pathogens. The use of oxygen absorbers also means that one need not use additives like BHA, BHT, sulfur dioxide, sorbates, and benzoates.

Silica Gel packets are small sachets containing the silica gel desiccant, which are mainly used to remove all traces of moisture from closed packages. The presence of moisture/water vapour in the packets can lead to the substances kept inside getting spoilt. It is to prevent such occurrences that Silica Gel sachets are placed alongside the packed goods. They are most commonly found in shoe boxes, display item packages among others. People mostly throw away the Silica Gel sachets as they think that they are not useful. However, Silica Gel sachets have many uses, which most people are not aware of. Scroll down to know why the next time you should not throw away the Silica Gel packet and keep it for any of the below mentioned uses.
Twelve major uses of Silica Gel Packets

Desiccants play an important role in the shipping industry. They help protect the merchandise being transported in ships against humidity. The goods are usually kept in boxes/packages and there is a fairly high chance that moisture can enter the packed space and spoil the contents. This is where the role of absorbers like cargo dry pak and desiccant unit pak become important. These desiccants are specially made for ship cargo and can keep the packed products vapour-free for the entire ship journey, which can last quite some days.
Effects of Changing Climates
Goods being transported in ships are susceptible to high levels of moisture for many days together as it takes a long time to reach their destination. The time taken may be weeks or several months. In such a scenario, it becomes highly important to keep the goods away from moisture as the latter will damage them and this in turn will lead to heavy losses. When one decides to transport goods by ship, the changing climate conditions of a sea route and their subsequent effect on the merchandise being transported must always be taken into consideration. The changing climate outside will cause condensation inside the boxes, thus putting the goods in danger.
Ship journeys are usually very long and if condensation takes place, then lot of moisture has to be withdrawn from the boxes. Other instances of humidity entering packed products happen when the container is not closed properly, thus provide an inlet for air and moisture.
Benefits of Using Cargo Dry Pak in Ship Containers
There are many advantages of using desiccants like cargo dry pak while transporting goods via ships. These include:
1) The desiccant can absorb almost all the atmospheric moisture present in the head of the package.
2) As ship journeys take up a really long time, desiccants are widely used as they can keep goods fresh for more than 50 days at a stretch.
3) These desiccants offer protection against all types of rust, mildew and corrosion, which can prove to be very harmful to the packaged products.
4) Desiccants like cargo dry pak are 100% environmental friendly and hence very safe for the environment. After their use, these moisture absorbers can be disposed of very easily and in a non-hazardous manner.
5) Other than ships, these desiccants are also used to keep products fresh while they are transported using other mediums like rail, air, ocean and trucks.
Viewing all the above-mentioned points, one can understand why container desiccants are so popular in the shipping industry.
