Protecting cardboard from humidity?

Hi all,

I recently moved house and I brought with me the original boxes for my home theatre. They are faily big and bulky, but they are also the safest way to move those big speakers the next time I move, so I would like to keep them. There is not a lot of space in the house, but there is big storage unit in the balcony. Now, the unit can be closed, so it wouldn't rain on those boxes, but humidity would definitely be an issue.
So, I'm wondering if there is a way to preserve my cardboard boxes in that environment. I will put a good amount of silica gel bags inside the boxes to deal with the humidity trapped in them, but I don't know how to keep the environment humidity out. My idea is to wrap them with "something" and I could use some advice on what that something coud be. Cellophane, cling film, something else?
Thank you very much for your help.

Will they fit in two plastic garbage bags? One on the top, one on the bottom, them wrap with packing tape to seal them. That'll keep any new moisture out. A few silica packs will remove any remaining moisture in there.

Extra points for using clear plastic bags so you can see if they start degrading for some reason.

Thank you. Looks like an idea worth investigating. Obviously, they'd have to be a bit thicker than the average domestic waste bags I see around, but I'll look into it.

Ive got original boxes for speakers and stereo equipment that are from back in the 80's and have been stored in the attic for almost 40 years with no issues.

If your attic or what ever is dry and well ventilated you have no concerns!
