Is the hole in the bag lined with a rubber seal? Or does the hole in the bag have slits to make the seal?

On my Hoover, the bag is sealed around the inlet with pressure and a tight fit only; there is no rubber seal nor are there slits.

Neither. The hole in the bag is faced with a cardboard seal that is matched to the bracket in the vacuum. The fit is machine specific.

I am sure it has rubber seal. But it is not tight like lockbox. I think it can just keep the beans' good smell for couple of days.

You just press the seal together - there should be a plastic tab on the top that you squeeze and run across the top. You sometimes have to squeeze hard to get the bag to seal.

No rubber seal. Have not tested to see if it's truly airtight, but shake that was kept in it for a few weeks was old, but not dry and still potent. Strong, good smell inside, no smell outside.

It is a resealable pouch with a ziplock like closure. i keep mine in an additional ziplock bag to keep it fresh. This product is awesome

It does not have a rubber seal or even a plastic seal, however...I filled it with water and tipped it over and back several times and it did NOT leak at all.

Mine was sealed in a plastic bag, but I can't say if it was air tight because I didn't stick it under water to test it. (shrug) Sorry I can't be of more help. I do know it works great in my Filter Queen defender.

Self-sealing means that it zips to close. It is not a fold-and-close bag and it does not require a twisty tie. There is no adhesive.

The bag cutter inside is a blade on a rail that you operate by hand. There is a lever on the right side that you lock down after you position the bag for sealing. You can walk away at that point and the machine vacuums out the air, seals, and stops. The sealed bag is still clamped in position by the lever until you release it.

I don't think the're airtight but the ones I have are defective. The "zip strip" is not attatched to both sides of the bag, so they don't seal at all. I have purchased these big zip bags for a few years now and have some old ones here but these are manufactured wrongly.

It is in a plastic bag, after you open it it will not be sealed again, I twist and wrap with rubber band

IMHO, if moisture is in the sealing area... it will not seal. the "trick" is to get your food into the bag without wetting the area to be sealed. e.g. use a much larger bag and fold the bag down so that the sealing area will be dry when the food is inserted. Food saver has a pricey bag "designed" to help avoid the problem- I do not know how well it works.

These are in the form of a roll and are not pre cut. The roll is sealed and perforated down the middle so you cut to length desired and can seal two bags at once and then tear down the middle or store them attached.

I'm not sure but I know it sealed a plastic coffee bag. You may have to simply shorten the seal time

No. It has a solid glass lid that makes contact with the ceramic interior. No rubber seal.

You have to put the plastic bag in the seal part and press the seal part down until it sucks out the liquid and then locks closed, then it seals but it doesn't always work. I bought the roll of bags and tried to seal the end before I filled the bag and it didn't work. I am not happy with the product.

In a plastic bag. It is not sealed. Has tape around constricted end of bag. It probably is not completely air tight based on that.
