Single sided cardboard - this stuff look ok?

Doesn’t say anything about acid-free, etc

Or do ya’ll have a better source?

B flute is rather small…….for rifle cartridges of all sizes, I use A flute. For 50 BMG, I’d go to even larger in flute size.

Thanks.

I have used almost 600’ of “Jumbo” flute single sided corrugated cardboard lining my dozens of steel blueprint file drawers, aluminum cooking cooling rack baking trays (great for dupes stored on a rolling baking tray rack) and any number of IKEA trays and boxes I use for sorting and transport.

I have has “0” issues with corrosion; but my room is in my homes HVAC controlled basement space.

I have never specified “acid free”…(as I think the commercial paper company would laugh at me)

I do have a 100 or more lead bullet (old school rimfire rounds) that I have noted no additional “white dust” corrosion you typically find from wood drawer storage…the white you see below…was “as received” (as far as I can remember)

What I did have happen; is that a third 250’ x 4’ roll (I had shipped to SLICS…4-5 years ago…to sell/trade off to the guys who always ask where I get mine for my table trays)…turned out to be a “smaller” jumbo flute than I previously and I wasn’t nearly as pleased with.

Six months ago I needed more and requested a sample and the jumbo flute arrived “white” faced…and I find that awesome in the new drawers I added

So you might be asking…where & and how much $ ?

It is a corporate paper product company in town (Green Bay, Wisconsin)(known for football and paper products…amoungst other things)

They would do me a favor and order “sample” rolls and I would pay the drop shipping…realizing that is a 4’ tall roll the width of a large refrigerator…it is truck shipped

There are lots of sources via Google…but not sure of “jumbo” flute (common the see “A” flute, etc…)

Here’s jumbo flute w/ 50’s

I’ve been using “A” flute corrugated paper for many years without any problems.

Regarding the question off “acid free” corrugated products, I’ve taken the following small step to insure safety. I spray the cut to size corrugated with a coat of polyurethane spray, such as DEFT or similar product.
