How do you seal the filled balloons so as not to lose the helium in them?

Traditional rubber balloons are a semi-permeable membrane, and helium molecules are small enough to pass through this membrane. There are products made for coating the inside of rubber balloons to reduce the permeability. Mylar balloon are not as permeable as rubber and lose helium more slowly.

I bought these tiny glitter containers from a craft store and did just as you said (freeze portions) the only thing is you must make sure no moisture gets into the tubes. I'm sure you could vacuum seal portions too.

I'd be afraid the squares would burst once they started to melt. Seal the sheet inside a big zip-lock bag, and if they did pop, at least it wouldn't make a mess. These do seem to hold the fluid better than the Cryopaks I was buying, but sitting on them? I don't know.

It is best to store the remaining o2 absorbers in an air tight environment. I use a food saver system to re-seal my o2 absorbers.Place the proper size o2 absorber in the mylar bag prior to sealing it. Just toss it in and seal it up.

They are packaged together, here is what you do to avoid waste...get everything together and in its proper bucket, crack open the absorbers, place one in each bucket or bag and seal. It will take less than a minute to seal everything. Other than that u can try keeping extras in a mason jar sealed. Not sure if it will work but worth a try.

It needs to be inflated with helium. You receive it flat, you need to add air.

These particular balloons are made to be inflated with air, they are not large enough to inflate with helium and float. Balloons 9" or larger are manufactured to be filled with helium to float. Thank you.Thank you!

They are not individually sealed. You need to seal the absorber each time you use one

This will not work on Mylar balloons! The opening on a Mylar balloon is not stretchy or flexible like latex and you won't get the seal you need! As previously pointed out it is just air not helium as well. Usually you can get the Mylar balloon filled from wherever you purchased it for no additional charge...

It will be time consuming but I think it will work. I blew up quite a few and it did a great job. The balloons won't float like Helium filled ones but I used sticky tac and stuck them to the ceiling that way with curling ribbon tails hanging down. You could order two pumps and have another person help you blow them up.

It does not come with any fill gas, you must provide that. Helium is recommended but I used air and hung it up with a string around the ears.That worked fine for me.

I don't know about helium. We used them as water balloons for the kids to bounce on.

"Tank" makes me think you are asking about helium not Hi-Float. A bottle as pictures (pint?) was enough for over 100 balloons for kids day at church and tablespoon or so left. We blew them up Fri. night and they were still floating at 100% thru Sat. The key is to squeeze the balloon after putting some inside so it coats the whole inside of the balloon. Each 9" balloon took about 1/4 to 1/2 teaspoon. Not sure how big a "really big" balloon is.

We have several birthdays all together so I bought a party tank of helium at EWal-Mart. It's easy-to-use and we have done 20-25 balloons. The kids love them.

I lined the sides, top & bottom with small bubble wrap. Then I lined the box I put them in. Be sure not to make it to heavy. I used several boxes.

It may be a big expense if you plan on using helium, I would price out that cost. The event we used the balloon was hung from a ceiling in a large hall. We filled it with a wet vac on low speed. No problems at all. Also customized the look of the balloon by painting it to the theme....it was one of the focal points of the event.
