I have a couple thousand rounds of the zqi SS109. I like the ammo. It's great for plinking and is fairly accurate for foreign bulk ammo.

The problem I have is the glue on the 30 round boxes is disintegrating. I don't want an ammo can full of loosepack 556 if I can help it. Is there a better storage solution?

I have lots of .223 loose in ammo cans. I throw in a small desiccant pack just in case.
What is you particular concern with having it loose?

Ammo can, works great.

I know you said you don't like loose but I fill up ammo cans with loose target ammo and throw in a desiccant.

You could buy some more magazines, and store all the ammo in magazines.

I don't see the problem with loose rounds either. All my bulk plinking ammo is either loose in ammo cans, or loaded into practice mags. When I'm headed to the range, I grab some loaded mags. When I get back from the range, I reload the empty mags from the loose rounds in the ammo cans.

If the glue on the boxes is disintegrating, I’d definitely consider desiccant. If you don’t want to keep the ammunition in bulk storage, how about individual plastic zip-lock bags? If you don’t have some way of sucking the air out of the bags before sealing them, I would squeeze out as much as possible and then keep a close eye on them to ensure no moisture forms inside or other problems like corrosion develop.

This is a sign that you don't have enough magazines or ammo cans.

to me its a sign you have a moisture problem the way your ammo is stowed away.
Let it dry itself off in a semi heated area for a few days and toss in 30 cal cans,those fifties are to damn heavy when you get old.
