Do the lids have silicone seals or is it just plastic on plastic?

There is what I'd call a gasket inside the lid groove; don't know if it's silicone, but it does seal well - not just plastic on plastic.

Yes the seal is a heavy rubber. As far as canning I don't know. I do know they are heavy glass. I got mine just to put sugar, rice, beans etc in them to have a rustic look. I do know they seal really tight.

The lids are all tempered glass and metal handles. There is a black rubber type ring in between the lid handle and the glass and I am not sure how high of heat that gasket can take. However, I have used mine in the oven and didn't seem to have a problem.

The lids seem to be of good quality yes. I haven't used them a whole lot thus far but they have been great the few times I've used them.

they are hard vented plastic lids. Supposedly supposed to be able to use in microwave but I have not used them in microwave yet.

The lid is plastic with what appears to be a rubber type ring to seal the jar. Great product.

Yes, Our jar had an aluminum lid with a rubber seal. I like it a lot but I thought there were three to a pack but it was just the one. Hope this helps. Good shopping.

The lids press in with a silicone gasket seal. They can be difficult to press the lid on, but seem to seal well.

The lids are plastic but as other people have said, they don't fit well. I ordered the set and 1 lid fit fine but the other 2 were much too loose. I returned the set.

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.

The lids are the only piece that are plastic, thus the only reason it would be labeled BPA free is if the lids are BPA free. BPA is not used in manufacturing glass. So... yes, the lids are BPA free.

The lids are a hard plastic. They kind of suction in the containers. They stay in pretty good.

The lids have a rubber gasket inside. They are very sturdy. I purchased to go with my CuiZen blender. And it fits perfect.

The entire lid is made of plastic, but the two interlocking plastic segments have a rubber (or it could be silicone) ring that seals the lid against the glass jar. It's rather ingenious.

Ummm....I think they are supposed to be. One of the lids has vents on it. I stopped using them pretty quickly since they won't stick to anything!

The jars are glass, the lids are plastic. They work great and I use my jars all the time... especially now that I have the lids with the straws in them and can access freshly made juices, etc away from home

They are made out of Silicone. Mine also leaked goo but i was able to easily get replacements and now i love them!
