How large are your posters? If they aren't too big, I put mine into art portfolio books

I have multiple. All prints in perfect condition for years
I would highly suggest not storing them rolled up in a tube. You can flatten them with a heavy item like a book or reverse roll them. There’s great videos of both methods on YouTube. As for storage before framing I recommend using something like This.
I got one of these for my big 18x24 Custom Correct maps, USGS quads, and my other large maps- an art portfolio book. It was more expensive than keeping them rolled up in a tube (free), but it's nice and satisfying being able to open a big book, look at a detailed map, close book, and put it away. Worth every penny.

You may be able to find one cheaper if you google around, but they get the job done. If money is no object to you, check out the Baroque portfolios. They are well built and durable (not that the itoya's aren't), but they cost a LOT more and there is often a wait time before they have enough to ship out.
No worries...
Keeping the prints rolled up in shipping tubes can damage the prints as well. It can cause issues as well when you attempt to remove them from the tube after a while.
The best this you can do for storage is buy a portfolio so you can store the prints flat and out of the sunlight.
You can get a pretty good quality portfolio here. $40

I only have so much space on my walls, I have about 25 frames posters up at a time and once I have to switch any out they go into this art portfolio I bought on Amazon. I'll have to buy another one after probably one more year of shows.
i'm confused. you need a portfolio for 1 print, or many prints. if they are 18x24 or smaller, this is the standard portfolio:
This is the defacto standard in portfolio:

but make sure you follow /u/metrodrone instructions about flattening.
If you have prints larger than 18x24 let me know and i will link you to a larger portfolio, but they get much more expensive.
What prints do you have?
Nice collection. I bought one of these works good https://www.amazon.com/ITOYA-Presentation-Portfolio-Photography-Documents/dp/B00009R8XD/ref=mp_s_a_1_3?dchild=1&keywords=18x24+portfolio&qid=1624119431&sr=8-3
