OXYGEN ABSORBERS
Absorbers | Oxygen absorbers
Oxygen absorbers allow you to extend the shelf life of meats, pastries, cooked products, bulk products, nuts, medicines and other foods by absorbing the oxygen present inside the packages in which the products are sold.
Thanks to the oxygen absorbers and the Ageless product range, an oxygen-free atmosphere is created inside the containers where the food is. Ageless oxygen absorbing sachets contain iron that oxidizes by absorbing oxygen from inside the containers, leaving an atmosphere of at most 0.1% oxygen.
With this oxygen-free atmosphere, food can be presented by eliminating the effects of oxygen. Both the taste and freshness of food are preserved, extending the shelf life of them.
Oxygen absorbers packets are a more efficient way to generate a nitrogen atmosphere inside the containers than is currently done with nitrogen injectors. By means of conventional methods of carrying out the vacuum and injection of nitrogen, oxygen pockets may remain at some point in the container and in addition to the passing of the hours, oxygen also enters through the permeability of the surface of the plastic film of the container itself. Thanks to oxygen absorber, a good elimination of oxygen is guaranteed at all points of the blister by a dynamic process.
We have oxygen absorbers in different formats and specialities: Ageless bags, Ageless Omac film, Pharmpakeep, RP System and Anaeropack.
AGELESS. Oxygen absorbers for food
AGELESS is the world’s first oxygen absorber for food. Deoxidize the inside of a sealed package in a way never before possible with a conventional gas and vacuum replacement gasket to preserve products and extend shelf life. The oxygen absorber is a simple and effective way to maintain the taste, color, fragrance and nutrition of food.
AGELESS OMAC Film
AGELESS OMAC is the next step in a line of quality oxygen absorbing products. Instead of having a bag to place in a package, AGELESS OMAC makes the package absorbent. These oxygen absorbers help liquid and pasta-based foods stay fresh for long periods of time after heat treatment, such as boiling or retorting.
Ageless Eye. Oxygen Indicator
AGELESS EYE is an oxygen indicator for monitoring the presence of oxygen inside a package. It is used together with AGELESS oxygen absorbers to check their effectiveness and to verify a good seal and the breathability of the packaging.
PharmaKeep
PharmaKeep is a special type of absorbent that can absorb both oxygen and moisture. It prevents oxidation and hydrolysis in pharmaceutical products and helps protect oxygen sensitive medical devices and equipment. PharmaKeep’s dual absorption of oxygen and moisture at the same time is what makes it so useful and special. PharmaKeep is suitable for dry medications and pharmaceuticals because it does not need moisture for oxygen absorption to begin.
RP System
The RP System was specially created to avoid the deterioration of industrial products and delicate cultural materials. The RP System works to protect goods and materials during transport abroad or for long-term storage. The RP System oxygen absorbers, also known as the Revolutionary Conservation System, absorbs oxygen, corrosive gases and moisture (Type A) in airtight containers to ensure the safety and protection of many different types of objects. One of the main uses of the RP system is to eliminate the oxidation of industrial and electronic products during transport and storage.

FAQs
Everything you need to know about oxygen absorbers and their professional application
What problems can oxygen cause in products and packaging?
Residual oxygen in sealed containers can cause oxidation of fats and active ingredients, loss of aroma and flavour, discolouration, proliferation of aerobic microorganisms and premature deterioration. In the food, pharmaceutical or industrial sectors, preventing these effects is essential to maintaining product quality and shelf life. Oxygen absorbers provide effective control of this risk.
What types of oxygen absorbers does Sercalia offer?
At Sercalia, we offer an advanced range of oxygen absorbers:
- Ageless-type bags with iron for dynamic absorption.
- Absorbent films such as Ageless OMAC for liquid or paste products.
- Oxygen indicators (Ageless Eye) to monitor internal levels.
- Specialised systems such as PharmaKeep (oxygen + humidity) and RP System for long-term storage.
Explore all available formats of oxygen absorbers from Sercalia above.
How do I choose the right oxygen absorber for my application?
The choice will depend on the volume of residual air, type of packaging, film permeability, product sensitivity to oxygen, and storage or transport conditions. For example, a food with a high fat content will require a fast-absorbing solution; an electronic device will require prolonged absorption capacity. At Sercalia, we advise you on choosing the ideal format, guaranteeing tailored protection.
What is the difference between the various types of oxygen absorbers?
The variants differ in terms of their mechanism of action (iron reagent, catalyst, active film), intended use (food, pharmaceutical, industrial) and format (bag, film, roll). For example, Ageless OMAC film acts as a total absorbent for the packaging, while traditional bags are an additional element. This differentiation determines the effectiveness, cost and integration into packaging lines.
What solutions does Sercalia offer for large volumes or long-distance transport?
For industrial shipments, long-term storage or critical components, Sercalia offers solutions such as the RP System, capable of absorbing oxygen, corrosive gases and moisture for months. This is particularly useful for export, art storage or international logistics.
Can I combine oxygen absorbers with other protection systems?
Yes. The combination of oxygen absorbers with modified atmosphere packaging (MAP), vacuum packaging, desiccants, or temperature stabilisers provides comprehensive protection. These systems work synergistically to control oxygen, moisture, temperature, and other degradation factors.
In which sectors is the use of oxygen absorbers recommended?
Oxygen absorbers are key in many sectors: food (cured meats, nuts, snacks), pharmaceuticals (capsules, medical devices), electronics, art and heritage (sealed storage) and the technical packaging industry. Sercalia works with these sectors, offering solutions tailored to each case.
Are oxygen absorbers safe for food or pharmaceutical use?
Yes. Sercalia products are formulated to comply with international food and pharmaceutical safety regulations. Reactive materials are encapsulated so that they do not migrate into the product, ensuring safe use in food, supplements, or medical devices.
How long does an oxygen absorber remain effective?
The duration depends on the capacity of the absorbent, the volume of air to be treated, the sealing of the container, and the permeability of the material. A good absorbent can maintain residual oxygen levels below 0.1% throughout the product’s entire useful life cycle.
