Questions about calcium hydroxide as co2 absorber.

[anthell]

I want to improve our company's packaging strategy for live seafood products.

The catch is, the box has to be sealed completely.
This causes problem with the ever increasing level of CO2 and not enough o2.

Now, since the box is tightly packed with the products and other materials for cushion (imagine
pieces of shredded paper or some sort), i am thinking of mixing a little bit of grinned calcium hydroxide powders into the shredded paper cushion.

As far as i can gather, this is not recommended because calcium hydroxide can cause irritation right?

now, can anyone clarify on this? or give alternate solution for my problem?
While we are at it, is there anyway i can provide oxygen in this confined space? The box would not be returned so if the method is very expensive, i wouldn't be able to do so.
Is there simple chemical reaction that is relatively cool/cold (the seafood product loves cold temperature), and safe ?
i would like to experiment if i can provide enough o2...

If however, there is a much simpler method, i would love to hear about that too.

One potential solution to your packaging strategy issue is to use an oxygen absorber. Oxygen absorbers are small sachets containing iron powder that absorb oxygen and other gasses from the packaging to create an anaerobic environment that helps to extend the shelf life of products stored inside. This could be an effective way to reduce the level of CO2 in your packaging without causing irritation or introducing any hazardous materials.You can also explore the use of modified atmosphere packaging (MAP) for your live seafood products. MAP involves actively changing the atmosphere within a package to one that is optimal for the product, usually by replacing the oxygen with a gas like carbon dioxide or nitrogen. This can help to extend shelf life, retard spoilage, and reduce microbial growth.If you're looking for a simpler solution that doesn't require specialized equipment and is relatively inexpensive, you may want to try adding some ice packs to the packaging. Ice packs can help to keep the product cool and can also help to absorb some of the oxygen within the package.
