When it comes to storing food and other sensitive items, Mylar bags have become a popular choice due to their durability and ability to maintain airtight conditions. One of the key components that make Mylar bags effective is the use of oxygen absorbers. These small packets are designed to remove oxygen from the bag, thereby preventing the growth of bacteria, mold, and yeast. However, a common question among users is whether it’s possible to put too many oxygen absorbers in Mylar bags. In this article, we’ll delve into the world of oxygen absorbers and Mylar bags to provide a clear answer to this question.
Understanding Oxygen Absorbers
Oxygen absorbers are small packets filled with iron powder, which reacts with oxygen to form iron oxide. This reaction removes oxygen from the surrounding environment, creating an anaerobic condition that inhibits the growth of microorganisms. Oxygen absorbers are commonly used in food storage, pharmaceutical packaging, and other applications where moisture and oxygen control are critical. They come in various sizes and capacities, with the most common being 50cc, 100cc, and 200cc.
How Oxygen Absorbers Work
The process of oxygen absorption is relatively simple. When an oxygen absorber is placed in a sealed environment, such as a Mylar bag, it begins to react with the available oxygen. The iron powder inside the packet oxidizes, forming iron oxide and releasing heat in the process. As the oxygen is removed, the environment becomes increasingly anaerobic, making it difficult for microorganisms to survive. The rate of oxygen absorption depends on factors such as the size of the absorber, the initial oxygen level, and the temperature.
Benefits of Using Oxygen Absorbers
The use of oxygen absorbers offers several benefits, including:
Oxygen absorbers help to prevent the growth of microorganisms, which can cause spoilage and contamination.
They prevent the oxidation of fats and oils, which can lead to rancidity and off-flavors.
Oxygen absorbers help to maintain the texture and color of stored food.
They can also help to reduce the risk of insect infestation and rodent damage.
Using Oxygen Absorbers in Mylar Bags
Mylar bags are made from a type of polyester film that is known for its durability and resistance to moisture and oxygen. When used in conjunction with oxygen absorbers, Mylar bags can provide a highly effective storage solution for food and other sensitive items. The key to successful storage is to ensure that the Mylar bag is properly sealed and that the oxygen absorber is sized correctly for the volume of the bag.
Calculating the Correct Size of Oxygen Absorber
To determine the correct size of oxygen absorber for a Mylar bag, you need to consider the volume of the bag and the initial oxygen level. A general rule of thumb is to use one 50cc oxygen absorber for every 1-2 gallons of storage space. However, this can vary depending on the specific application and the level of oxygen control required. It’s always better to err on the side of caution and use a slightly larger oxygen absorber than necessary, rather than risking inadequate oxygen control.
Potential Risks of Too Many Oxygen Absorbers
While oxygen absorbers are generally safe to use, there are some potential risks associated with using too many in a Mylar bag. These include:
Over-Absorption of Oxygen
If too many oxygen absorbers are used, they can remove too much oxygen from the environment, creating a vacuum. This can cause the Mylar bag to collapse or become misshapen, which can lead to a range of problems, including reduced storage capacity and increased risk of contamination.
Increased Risk of Nitrogen Displacement
When oxygen absorbers remove oxygen from the environment, they can also displace nitrogen. This can lead to a range of problems, including the formation of nitrogen pockets, which can cause the Mylar bag to become bloated or misshapen.
Best Practices for Using Oxygen Absorbers in Mylar Bags
To get the most out of oxygen absorbers and Mylar bags, it’s essential to follow some best practices. These include:
Using the correct size of oxygen absorber for the volume of the Mylar bag.

What are oxygen absorbers and how do they work in Mylar bags?
Oxygen absorbers are small packets or sachets that are designed to remove oxygen from a sealed environment, such as a Mylar bag. They typically contain a material that reacts with oxygen to form a stable compound, effectively reducing the oxygen levels within the bag. This process helps to prevent the growth of bacteria, mold, and mildew, and also inhibits the oxidation of foods and other materials. By removing oxygen from the bag, oxygen absorbers help to preserve the freshness and quality of the contents, making them ideal for storing food, clothing, and other items.
The use of oxygen absorbers in Mylar bags is particularly effective because Mylar is an impermeable material that prevents oxygen and moisture from entering the bag. When oxygen absorbers are added to a Mylar bag, they can effectively remove all of the oxygen from the bag, creating a vacuum-like environment that prevents the growth of microorganisms and the degradation of the contents. This makes Mylar bags with oxygen absorbers an ideal storage solution for a wide range of applications, including food storage, emergency preparedness, and long-term preservation of clothing and other textiles.
Can you put too many oxygen absorbers in a Mylar bag?
While oxygen absorbers are generally safe to use, it is possible to put too many in a Mylar bag. Using too many oxygen absorbers can cause an excessive reduction in oxygen levels, leading to a vacuum-like environment that can be difficult to seal or open. Additionally, excessive oxygen absorbers can also lead to the formation of nitrogen gas, which can cause the bag to become over-pressurized. This can lead to a range of problems, including the bag bursting or becoming misshapen.
To avoid these problems, it’s generally recommended to use the minimum number of oxygen absorbers necessary to effectively remove oxygen from the bag. The exact number of oxygen absorbers required will depend on the size of the bag, the type of contents being stored, and the desired level of oxygen removal. As a general rule, it’s best to start with a small number of oxygen absorbers and monitor the bag’s oxygen levels over time, adding more absorbers as needed to maintain the desired level of oxygen removal. This approach helps to ensure that the bag is effectively sealed and preserved, without over- or under-removing oxygen.
What happens if I use too many oxygen absorbers in a Mylar bag?
If you use too many oxygen absorbers in a Mylar bag, you may experience a range of problems. One of the most common issues is that the bag may become over-pressurized, causing it to burst or become misshapen. This can lead to a loss of seal integrity, allowing oxygen and moisture to enter the bag and compromising the preservation of the contents. Additionally, excessive oxygen absorbers can also cause the formation of nitrogen gas, which can lead to a range of problems, including the bag becoming brittle or prone to cracking.
In extreme cases, using too many oxygen absorbers can also lead to a phenomenon known as “bag collapse,” where the bag becomes so over-pressurized that it collapses in on itself. This can cause the contents to become compacted or crushed, leading to damage or spoilage. To avoid these problems, it’s essential to use the correct number of oxygen absorbers for the size and type of bag being used, and to monitor the bag’s oxygen levels over time to ensure that the desired level of oxygen removal is being achieved.
How many oxygen absorbers should I use in a Mylar bag?
The number of oxygen absorbers required for a Mylar bag will depend on a range of factors, including the size of the bag, the type of contents being stored, and the desired level of oxygen removal. As a general rule, it’s recommended to use one 100-200cc oxygen absorber for every 1-5 gallons of storage space. However, this can vary depending on the specific application and the level of oxygen removal required. For example, if you’re storing highly oxygen-sensitive materials, you may need to use more oxygen absorbers to achieve the desired level of oxygen removal.
To determine the correct number of oxygen absorbers for your specific application, it’s a good idea to consult with the manufacturer or supplier of the oxygen absorbers and Mylar bags. They can provide guidance on the recommended usage rates and help you to determine the optimal number of oxygen absorbers for your specific needs. Additionally, it’s also a good idea to monitor the bag’s oxygen levels over time, using techniques such as oxygen indicator strips or portable oxygen meters, to ensure that the desired level of oxygen removal is being achieved.
Can I use oxygen absorbers with other types of storage bags?
While oxygen absorbers are commonly used with Mylar bags, they can also be used with other types of storage bags, such as polyethylene or polypropylene bags. However, it’s essential to note that these types of bags are not as impermeable as Mylar, and may allow oxygen and moisture to enter the bag over time. As a result, oxygen absorbers may not be as effective in these types of bags, and may require more frequent replacement or monitoring to ensure that the desired level of oxygen removal is being achieved.
To use oxygen absorbers with other types of storage bags, it’s recommended to follow the same general guidelines as for Mylar bags, taking into account the size and type of bag being used, as well as the desired level of oxygen removal. However, it’s also important to be aware of the potential limitations of using oxygen absorbers with less impermeable bags, and to monitor the bag’s oxygen levels closely to ensure that the desired level of preservation is being achieved. Additionally, it’s also a good idea to consider using other preservation methods, such as desiccants or nitrogen flushing, to help maintain a stable storage environment.
How do I know if I’ve used the right number of oxygen absorbers in a Mylar bag?
To determine if you’ve used the right number of oxygen absorbers in a Mylar bag, you can use a range of techniques, including oxygen indicator strips, portable oxygen meters, or vacuum gauges. These tools can help you to monitor the bag’s oxygen levels over time, and determine whether the desired level of oxygen removal is being achieved. Additionally, you can also look for signs of effective oxygen removal, such as the absence of rust or corrosion on metal objects, or the preservation of food and other perishable items.
If you’re unsure whether you’ve used the right number of oxygen absorbers, it’s always better to err on the side of caution and use a smaller number of absorbers to start with. You can then monitor the bag’s oxygen levels over time, and add more absorbers as needed to achieve the desired level of oxygen removal. This approach helps to ensure that the bag is effectively sealed and preserved, without over- or under-removing oxygen. By monitoring the bag’s oxygen levels closely, you can help to ensure that your stored items remain fresh and preserved for as long as possible.
