Poly Zip Bags For Sorting And Storage-- OK?

I need some type of inexpensive but safe way hold and label sorted coins. Given the quantity (~10,000 coins, 3/4 are dimes, nickels, and cents), cost is an issue.

Are polyethylene bags safe for this? Any specific brand recommendations?

I'm thinking ~2x3" (or smaller) would be a good size, preferably with a white area on the outside for labeling. I could put those in 2x2 boxes after sorting, with paper dividers stuck at appropriate places, like between dates.

I might get a smaller number better containers for coins that are more valuable-- air tights, mylar flips, whatever.

I'm looking at various suppliers-- Wizard, RioGrande, etc, and need to order them very soon so that I'll have them for my Christmas Coin Sorting Marathon

Your input and advice is appreciated.
