Is This Damaging?

[Brachra]

So because I can. And have 50 lifetimes of vaccubags and foil tape available. I tape my tins and vacuum bag them now.

But I decided to try it on a C&D tin.... Do any of you think this is bad?

Im not here to discuss whether or not any of this is necessary.

Just worried that I can see the Poptop shape in the lid now.. Its the only one I've done I figured its another excuse to use up these bags. But if this is gonna damage the cans I won't. I know some of you here store this way so I hope you can chime in here.

I keep all my tobacco in Coleman Coolers in these bags (aside from jars which are in a big tote)

Not sure what damage could be caused. I've received tins in trade where people have done something similar.

You should see how they treat tobacco before packaging it. Do whatever you want, you won't damage anything.

Not worried about the tobacco... I was worried about the very noticeable extra force on the lid of the C&D tin

The extra force on the lid pushing down onto the sealed pop top of the C&D tin was worrying

As long as the tins' seals are intact it should be fine. Gasses escaping a leaking tin react badly with some plastics and can form an unstable compound called tobaccanite. When tobaccanite is kept in ambient temperatures between 60-75°F it's safe. Anything above or below can cause the compound to explode.

You got me there for a sec. I even looked it up

You created a vacuum in the bag, including beneath the lid, so you're now seeing the ambient air pressure, approximately, 15 psi, pressing the lid onto the tin. Is it bad? I've no idea, but suspect not.

What type of vacuum bags are you using?

4mil poly nylon vacuum bags

Cool just check the shelf life expectancy on that thickness.

Some forum members have cautioned against vacuum sealing tins as the pressure may cause the factory seal to pop - I still seal my tins, but I originally sealed some stuff in 3mil food saver grade bags and have since resealed them in mylar bag as I didn’t realise that after a couple of years they can let vapour/oxygen out. I now use micro channel vacuum bags for sealing as they offer the same protection as 7mil Mylar but can still be used with a domestic food sealer ✌?

Care to link the bags you use?

Also I'm sure it doesn't help but thats why I foil tape the tins ans hold them down whilst the bag seals....figure that eliminates any reverse vacuum unsealing magic.

I’m based in New Zealand so this is what I use. Mylar is incredibly expensive here too.

Thank you!
Oh yeah..those are kinda pricy. Im in the US.
If you want to....I would appreciate If you or anyone else could help me locate something similar.

There aren't really a ton of specs on this besides the description sounding awesome. And of course everything on Amazon is like "WE HAVE THE BEST BAGS! NEVER FAILS"...etc.

i don't even know where to begin.

Edit: If i do search for "Micro channel bags"
They all seem to be AU or NZ websites...quite a few.

Are they called something else In other parts of the world?

I'll be watching for a recommendation as well

If you really want to seal 'em up good, cast them in epoxy resin...

@rajangan where do you get your bags from?

I've got a pipe I'm planning on doing that with. My kids are big into that and I figured I'd give it a go.

The vacuum seal bags are from a butcher and tanning supply place. They don't keep moisture in 100%, but they are much better than freezer bags. If kept in a sealed bucket, they do last.

Screw the bags, what kind of vacuum sealer are you using that gets that kind of "suck"? I am going to need a new one soon...
