Why doesn't this bag have a seal like other bags to prevent leakage into the canister?

Likely because it would cost more in development and production costs. They had to skimp somewhere to sell the bags at half price.

The ziploc bags are not air tight. They have a zipper around the top so should stay shut but also have a narrow mesh around the top and are not vacuum sealed.

I use Ziplock brand bags with success. With any bags you use, take extra care to make sure the bag is locked securely. I press the edge down several times all the way across to make sure there is no leak at the seal. Then I check periodically to make sure it is still sealed. If air is leaking back into the back I just zap it with the sealer again.

No. There is no seal. Also, the section in the picture that is black are the two removable tote trays. They are also not sealed.

There is a thin rubber gasket around the lids, this makes the seal very secure. I have had the canisters for several months and have no problem.

I believe, as an additional accessory, you can purchase vacuum seal canisters for this unit. I have only used it with bags. The canisters due work with the accessory port. Hope this helps.

Mine has never leaked from where the lid and jar form a seal. However, it would be easily spilled in a lunch bag because of the holes for drinking and air flow.

are you using the foodsaver brand bags? the Weston bags I have a problem with it holding its seal, but the foodsaver brand I've never had an issue with. do you have "quick" seal selected or "normal"? that may make a difference as well. if you are sealing meats, I've sometimes had an issue if liquid from the meat seeps up into the seal area, solved it by putting in a ziplock first, then the Foodsaver bag, then sealing as normal. hope this helps somewhat!

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.

You just need to get as much air out of the bag as possible to improve contact between it and the water. I just happen to already own a Food Saver machine so use it to vacuum and seal my food that I cook. The material I have read says a heavy duty ziplock bag work well also.

It has a small suction cup at the end of the nozzle. I imagine it will be able to seal any type of bag that has a one way valve.

The instructions show that there is a tray for catching excess liquids being removed during the process, and I find that mine unit does remove liquid so the bag can be sealed. Due to this, I find it highly unlikely that you could seal liquids in the bags. Also liquids can be a problem if they end up where the bag is being sealed. Foodsaver does offer the ability to vac-seal mason or canning jars, plus other containers that they offer. I have not attempted this yet, but the Foodsaver website does show more details and better explanations of their options.

I second JarCie's reply. As for sealing items with fluids (e.g. fresh meat) I suggest having a bit longer bag then watching the flow of fluids. As they approach the sealing area, press "seal" to stop the suction and commence sealing. This ensures a good seal.

Actually, there is a way to do it: cut strips of Foodsaver bags about 1" x 6" and discard the smooth side. Insert the checkered strip lengthwise into the bag, leaving about 1/2" sticking out. Seal as usual (with oxygen absorbers), making sure the strip is pushed down into the vacuum chamber. The checkered strip serves as a pathway for the air to be pulled out of the bag.I have an almost 100% success rate using my $30 Rival vacuum sealer. Never had a problem with the sealer not being hot enough.

These are giant plastic bags, without the locking seal. I suppose if you got creative you could roll it and, with help, tape it up while still keeping the air out, but there is nothing to seal on the bag.

The key to getting a good seal is if the bag is not filled completely. I just squeeze the air out and roll the top over a couple of times and I get a perfectly dry seal every time.

The plastic needs to be food grade. When talking about vacuum sealed bags, that isn't hard to verify or achieve since the major brands all have food grade plastic available for their machines. The trick lies in using "ziploc" type bags when you are using broth or other liquid which can't be vs'd without freezing or simply don't have sealer at all. I don't have the concerns about leeching plastic but there are websites out there that have done research and hunted down solutiions. No links, sorry.
