Are you looking to keep your products protected from oxygen or moisture? Did you know that there are different solutions available depending on whether you are looking to protect specifically against oxygen or humidity? In this article, we will share two solutions that can help keep your items in their original states for a longer time.
What Are Oxygen Absorbers?
Oxygen Absorbers absorb oxygen and are usually used in the food industry to prolong the shelf life of food. They are tiny packets that contain a mix of 3 components - iron filings, salt, and clay.
How Does Oxygen Absorbers Work?
When Oxygen Absorbers are exposed to oxygen, a chemical reaction takes place where the iron filings absorb the oxygen. The Oxygen Absorber is able to bring down the volume of oxygen in a good packaging up to 0.1%. It is essential to use the Oxygen Absorbers with high oxygen barrier food bags & pouches for maximum shelf life.
Why Should I Use Oxygen Absorbers?
- Extend the shelf life of food by preventing the growth of microorganisms
- The natural way of maintaining the nutritional content of food - Oxygen Absorbers prevents food from oxidising, which removes some beneficial properties of the food such as Vitamins A, C, and E
- Safe and easy to use
- Retains food colour
Examples Of Oxygen Absorbers Applications
You can find Oxygen Absorbers used in food packaging such as:
- Pet Food
How Should I Use Oxygen Absorbers?
Place the small packets of Oxygen Absorbers into the packaging of the items you want to protect against oxygen. Stream Peak’s Oxygen Absorber, O Sorb, is made from safe, non-toxic material and can be placed together with food in its packaging. Without any aerobic bacteria and fungi growth, the shelf life of a food product can extend from 1 week to several months.
What Are Silica Gels?
The primary purpose of Silica Gels is to remove moisture. They are also commonly used as desiccant bags and are made from silicon dioxide, which is porous sand. Silica gel bags are often used together with humidity indicator cards and moisture barrier bags to ensure maximum protection against humidity damage.

and their application.
How Does It Work?
Silica gels contain millions of tiny pores on their surface that can contain moisture. Silica gel can be supplied as indicating gels which allow a visual indication of the desiccant when it's fully saturated. The indication allows the user to know when to replace the desiccant. The other alternative would be to manually weigh the desiccants as they can hold up to 40% of their weight.
Why Should I Use Silica Gels?
- Prevent damage to your expensive items from the growth of mould caused by moisture and dampness
- Safe and easy to use
Examples Of Silica Gel Applications
- Leather products
How Should I Use Silica Gels?
Place the tiny packets of Silica Gels into the packaging of the items you want to protect against moisture. Stream Peak has three types of Silica Gels with different features, including a colour change feature, which indicates when the Silica Gel needs to be changed.
