All times are based on storage at room temperature, 21 degrees.
However, a lower temperature can extend the times below considerably. Every 5.6 degrees lower temperature, the storage time is doubled.
A product that can:
10 years in 21 degrees can thus cope
20 years at 15 degrees
30 years at 10 degrees and
40 years at 4 degrees.

In addition to the storage time being radically extended, all insects, larvae and eggs also die in the oxygen-free environment. It can take up to 12 days and requires an oxygen level of less than 1%. But with the right number of oxygen absorbers, the oxygen level will be about 0.1%. This is something you only achieve with the combination of Mylar and oxygen absorber.
Mylar.se sells oxygen absorbers in the size 300cc.
This consumes oxygen in about 1.2 l of air.
You can order these in 20 or 100 packs here.
