Greg welcome to the forum.
A dumb question is the one not asked. As for a sealer, I would not use that to preserve a coin. I don't know what the plastic is made of, but if it contains PVC, it could damage your coin. There are hundreds of products on the market today that are made for long term storage. I would consider one of these over a sealer.

I do something exactly like that only I don't spend the money on a specialty product for that purpose. What I do is simply take a standard zip lock freezer bag and encase each Whitman Classic Album that I am not going to open for a while and squeeze out as much air as possible. Not sure how long I've been doing this so can not give a long term report. Prior to the invention of the zip lock I used to use just a plastic bag. The PVC stuff is so greatly overexagerated I never worried about that myth. I've been doing this for well into the 30 or more year area and will let you know if there are any adverse effects over the next hundred years or so. Most coins look just the way they did when I put them in the albums.

what I was thinking of using it for are the rolls of GW $'s and putting it aside for the kids (if they don't spend all my money before I get to to bank lol)maybe if I wraped them in saran wrap before I put them in the air tight wrapper it would be ok ?  |

Not intending to hijack the thread, but...
I was at my mother-in-laws house a few weeks ago and her husband got out his coin collection. He mentioned that he hadn't even looked at it in over 20 years.
He had Whitman folders for pennies, nickles, dimes, and quarters. He mentioned that he had a "damned near brand new 1909 VDB" in the penny album. And he did. But he had also noticed that the coins were "kinda loose" in the folders, so every coin in every folder was scotch taped down. For 20 years.
He also had probably 75 dimes and a hundred or so quarters, each individually wrapped in scotch tape. To keep them safe.

I've never trusted bags or wraps to store coins raw. Not even the polybags that are sold for coins. I don't know how safe they are but they always felt a bit oily to me. I do wrap Whitman boxes though with Hefty one gallon bags. I cut the sealing end off each bag and run one across each end of the box so they over-lap, and then wrap the bags tight with rubber bands.

Greg, I use one of those, but not to store my coins. When I mail a handful of coins I vacuum-seal them so they don't jingle in the package/envelope. mila_ |

Two things First food plastic is probably low or high pressure polyethylene PVC does not make it to the Food Contact grade I think There are a dozen nice plastics outside of PVC like Acrylic for hard capsules Second for sealing all coin lots or albums I have read on a German forum the members use their deepfreeze sealing vacuum equipment regularly for sealing coins . I would think that on an album or a sealed roll this practice has zero risk If there were no fingerprints under the scotch tape the condition of the coins after acetoning may be a nice surprise . I have several coins that were actually glued on pages to keep them in place |

To settle this issue of preserving coins, why hasn't someone asked
a test lab, etc for their opinion? I am confused with all of
the writings on this subject. I am also surprised that Dansco, Whitman,
Littleton, etc. haven't weighed in on this issue.

I worked 8 years with testlabs
There are the two eternal questions
What testprotocol should be used ?
One 1000 hours in UV light shining on Florida 100% moisturised air
enriched to 100 ppm pure sulphur dioxide and heated to 50 C for good measure ? Oh and lets add two bars of pressure to be sure .
And if you agree on the testprotocol what measurement are you going to use
Discoloration? Corrosion ? Loss of weight ? Difference in selling price ? Sulphur content inside the wrapping ?

Also, keep in mind that in order for PVC to affect the surface of the coin - it has to be in direct contact with it. So, if you put a coin is a non-pvc flip prior to sealing it - you should be good.
