Seal on Powder Bottles: Keep It?

[Clancy]

For the last 20 years, I’ve been able to keep the seal that came on the bottles, but I tore one up pretty bad and decided to chunk it and just use the seal in the cap.

I just wondered how important that is and if I’m the only weirdo that kept them.

Several brands don’t even have a seal. Are any of them actually air tight?

What do y’all say?

 

[Bill Norris]

I keep it too.

From the information shared in another thread, I would replace the seal - I'm currently using a couple layers of plastic wrap.

Throw a desiccant bag in each one to absorb any moisture inside. I do this with both powder and my ammo boxes.

I keep my seals best I can. If it gets messed up, so be it. Sometimes I'll take a seal from an empty bottle and add it a bottle that has one that is all torn apart

I tighten the lid the best that I can and then squeeze the container to make sure no air can escape. That’s how I verify the seal is good.

If you rip the seal removing it, Scotch tape the rip and trim the tape on the outer edge.

That’s a good idea, may even do it.

I put a couple of layers of plastic wrap on it for now. Normally I wouldn’t care, but it’s a jug of H4895 and I probably won’t ever buy another as I’ve swapped to Vihtavuori so I’d like to have it sealed up. I only opened it as part of my periodic powder safety check.

In the past I have used electrical tape in the same way

Several layers of Saran wrap between the cap and bottle.

I've been waiting for someone to come up with vacuum seal caps bet they would sell!

Does any air ever push out?
I have never put much tho in to it, but one would think that threaded plastic cap with a seal of its own would be sufficent.

I tested this yesterday by squeezing the bottle and screwing the cap on, and it would take it 8-12 hours just to pull enough air in (under vaccum) to decompress the bottle.

So, I think the caps work pretty well.

But, since this is Hodgdon and will probably be worth a new car someday, I’m going to use the wax paper suggested by Rick Smith. The plastic wrap was bad about tearing when I put the cap on.

 

[Clancy]

Wax paper with an Elmer’s glue stick around the rim worked better than expected.

I usually lay a sandwich bag across the top and screw it down. I like the wax paper idea though.

I quit breaking the seal several years ago. I take a sharp utility knife and cut a slot in it. Then use the slot to pour out the powder. Slot design your choice.

Brilliant!

Y'all know that plastic is permeable, right?

Take an empty jug and put some water in it. Put the lid on tight! turn it bottom side up. Squeeze it and see what happens.
