Ageless Oxygen Free Storage, Oxygen Absorbing Sachets

AGELESS oxygen absorber packets were developed for the food packaging industry for use inside high oxygen barrier film packets sealed with or without a vacuum. The AGELESS sachets are capable of reducing the oxygen inside an airtight container to less than 0.01% (100ppm) and can maintain this level indefinitely depending on the oxygen permeability of the packaging material. Long term packaging of Museum objects requires a packaging material that is virtually impermeable to oxygen. Recent research work carried out within Museums has found oxygen free storage to have many benefits for the storage of historical objects. Many of these objects contain modern or synthetic substances that can deteriorate even in the best conventional archival storage materials available. This is because although they are pure and non reactive, they do not tackle the problem of excluding the main cause of deterioration oxygen. AGELESS is also used in conjunction with barrier film for the irradication of insects and pests.

Various types of AGELESS can be supplied for Museum storage but the most common is the AGELESS Z and AGELESS RP which we list here. Other types have been designed primarily for specific types of food packaging. These may be of use for selected Museum storage and full details can be found in the Mitsubishi AGELESS technical literature which we are happy to supply on request. This information details how to measure the amount of AGELESS needed for a certain size of package. However, as a general rule it is better to use too much than too little. Results can be checked using AGELESS EYE oxygen indicator tablets.

Ageless ZPT

AGELESS Z used in conjunction with moisture permeable, transparent, laminate, oxygen barrier bags; similar to our ArchiPress Pouches, is recommended as an insecticide of non metal artifacts for short periods of around one month. ESCAL or Aluminium Foil should not be used because they will retain the moisture given off during the active period of the AGELESS Z . However, if the high humidity adversely affects the artifacts, even if it is for a short time, use AGELESS RP-K

RP System Type A

Removes: Oxygen, moisture and corrosive gases

MITSUBISHI RPA "stop the clock" on the sources of corrosion and oxidation of metals through a chemical reaction that removes oxygen, moisture and corrosive gases from sealed containers. It is used in metal conservation and other applications where a low RH is required i.e. geological specimens. It may also have applications for the storage of audio tapes where oxygen and moisture are primary sources of deterioration. Much experiment is still needed to be sure of the range of applications.

RP System ™ Type K

Removes: Oxygen and corrosive gases

Does not affect the moisture in a container and is used mainly to protect photographs, films, dyed products from discolouring and fading. (U.V. Light damage is reduced with the absence of oxygen). AGELESS RP-K also prevents mildew and insect damage to paper, textiles and wooden artifacts.
