Oxygen Absorbers & Desiccant for Time Capsules: Handy Chart

Oxygen Absorbers & Desiccant

Conditioning Agents

Finally we have a chart that designates a certain amount of oxygen absorbers for each of our time capsules. It does not go by total time capsule volume (cu. in.), but rather is figured on the head space of a time capsule that's considered to be 3/4 full by height. The last number given in our time capsule dimensions is always the height in inches (L x W x H).
desiccant packets
Desiccant Packets make it easy to keep your time capsule items dry during storage.

As always, a disclaimer: you may need more than so designated if your time capsule is less than 3/4 full of items. If you have more than that shown or calculated, it's not considered a problem.

In practicality, when we cannot give you the exact amount below, we round up - so that for 2900 cc you will likely get 3000 cc. It's a factor of what we have in stock at the time we fill your order. When we package the absorbers in the special Marvelseal® MVP bags, extracting the air, we try to make them in the amounts sold separately (e.g., 2 packs of 300, 3 - 300, 2 - 500, 2 - 1000 and so on). The packs are clearly marked, and - a bonus - you get the formula for calculating them on your own included with the info leaflet attached to the packets. This updated chart shows the desiccant that we calculate, too - although you'll want to revise that depending on your contents and cushioning materials. If you have a lot of paper, you may need more desiccant in your time capsule. As a general rule, add 1 unit of extra desiccant to your capsule for each pound of paper you have to go inside.

The following amounts have been updated and are current as of Nov 2015. In most cases we have increased the amounts given for both Oxygen Absorbers and Desiccant. Number in parentheses indicates the amount normally given to customers for that size.
