What material is the inside of the lid made of? So many lids are plastic inside. Silicone would be acceptable.

It's actually stainless steel. I'm not sure what connects the stainless steel to the plastic on the outside. I'm going to assume a silicon but I'll update my answer when I don't leave it at work!

The inside surface of the Wide Loop Cap lid (the cap that comes standard) that contacts the contents of the Klean Kanteen is made of two materials: most of it appears to be the same Stainless Steel that the body of the Klean Kanteen is made of; the other part is a gasket that seals against the lip of the body. On the Klean Kanteen website I couldn't find what that gasket is made of, but it appears to be silicone or plastic; however, very little of the contents will be touching that gasket. I'm not sure of the construction of the other lid types, but you can go to http://www.kleankanteen.com/products/insulated/klean-kanteen-insulated.php to find out the specs.

The gasket is medical grade silicone, it is removable to clean thoroughly, although it is somewhat hard to remove and replace it can be done with a flat, slender, round edged metal tool like this Tweezerman No-Slip Skin Care Tool

The inside of the lid is stainless steel but the outside of it is a type of plastic

The inside of the standard lid (or at least the part that will touch the liquids) is stainless steel.

They are made of plastic. If you have had problems with plastic containers before, I would recommend something else made of glass.

It's a black lid. I'm pretty sure it more of a metal material but it seems like it's lined with plastic, if that makes sense.

It's possible it could be mad of silicone. It's a very thin plastic material but it works great for me. The only downside I have noticed is the cover shield when you are in the sun is kind of hard to see it, but it doesn't take much to open it up if you need to

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.

The cover/lid is metal. The product appears to be entirely made of metal. I don't use it; my wife does and she really likes it.

According to research it is silicone. I've used mine very often and not a single problem.

Some sort of plastic. I didn't keep the packaging so I'm not 100% sure, sorry. But the pas, lids, spatulas, and food are all plastic

The inside is plastic. I use them to make tinctures, so I had to make sure that there was no cardboard on the caps.

I second Sylwia's post. The lid may not be BPA free. That typed, the stuff they use to replace BPA is just as bad as BPA, so if it's a concern for you, I'd recommend going with something that is stainless steel all the way.

It is made from silicone. It holds the lid onto the pot - not a tight seal like a gasket would create, but it keeps the glass lid from knocking into the glass body of the pot.

The inner seal seems to be the usual "rubber" seal. I don't know, because they do not say. I would guess that it is a man made material, just because real rubber is not used much any more.The seal does seem to be the usual seal that you would see in any lid with a seal.

it is all stainless steel inside, except the lid is hard plastic.don't know if the lid is bpa free

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.

The inside parts of the lid are plastic and there is a silicone rim to keep the grounds from going around the mesh. We use ours every weekend since we bought it and it does not feel flimsy in anyway. It's actually very well made.

The outside is glass, the strainer inside is clear plastic and the lid is rubber or silicone covered. The inside sipper is plastic. Hope that helps
