Chosky 100PCS Mylar Foil Bags Flat Vacuum Seal Bags Aluminum Foil Smell Proof Pouches Long Term Food Storage Bags 6.3"x 9.4"

Perfect Mylar pouches. However, they only hold a vacuum seal when you use a chamber vacuum. Will NOT work with a food saver type sealer for a vacuum seal, though they will seal. With my chamber vac, they work flawlessly. I used the bags to break down and vacuum seal a big bag of indigo powder into smaller portions that stay fresh.

I tried to seal repetitively with different bags. Out of 15 bags 1 sealed. Not sure if the thinness or the actual material was at fault. All I know is that it just didn't work.

I wanted to vacuum seal but these wont without a trick. Lots of tricks on google but they are all a pain. They do seal just won't pull a vacuum. I'll stick with the regular seal a meal bags for storing my hops.

Does what they’re supposed to! Easy to heat seal and easy to open once sealed!

Even though they’re called vacuum seal bags they will not work with a vacuum sealer as they have no place for the air to be sucked out of the bag, I wouldn’t recommend if you plan on using it with your vacuum sealer system.

If they offered 0 Stars. That's what I would rate these for Vacuum Seal Bags!!! Even with the vacuum bag "Shim" trick. It Didn't work!!Good mylar bags. BUT!!!!!! NOT!!!! Vacuum Sealable At All!!!!

Simple bags perfect for my loose leaf tea.

Bags don't vacuum seal in a foodsaver even with all the hacks out there to do so.
