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.

I would not put this lid in the oven. Even if the silicone could handle it, the plastic center would be ruined.

Yes this cover is made of silicone, but it is durable enough to feel like plastic, to enable for it be to collapse for easy storage, I just keep it in the microwave at all times.

The plastic water-level window is plastic but I don't believe it's lined with a silicone seal. Also, there's a metal mesh strainer but it's lined by plastic as well (again, no silicone). OH and the lid's mostly plastic.

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.

The lids are a thicker and harder plastic as compared to the container which is more rubbery. Also, I think I saw someone post that the contents don't come out easily... if you put in a shallow cup or bowl of warm water, or run under warm water, the contents come out with ease and perfectly clean.

The exterior of the lids are silicon, and i'm fairly certain the the middle of the lids are polycarbonate with a thermal weld between the two, but the manufacture data isn't exactly clear (if it was you wouldn't be asking). no info on the country of manufacture

The packaging said it is food grade polyproplene. I think if you wanted a straight sided glass jar with lid (like would be used for canning) could be used inside were the actual yogurt is being produced. And they do make some of the lids for these in a plastic so as not to have,a metal canning lid. Best suggestion I can give you.

Glass is BPA free. Even if the plastic lid is BPA free doesn't mean it's safe. They replace the BPA with another chemical. And I'm pretty sure it isn't safe either. this is what i found about siliconeIf plastic can't be avoided altogether, the safest type (meaning the most stable, slowest to degrade and leech chemicals into your water, food, etc.) is silicone.There is a lot of debate on silicone leaching chemicals. I did read some where that it's least likely in silicone that isn't heated up. As in the ones you cook with.So glass, 100% natural rubber and metal are the best I've read Glass is BPA free.

The lid is made of sturdy translucent plastic, with a rubber O-ring (about the thickness of my pinkie finger) that seals the lid against the glass.

The top of the lid is metal, but the underside is plastic. Well made, thick, not at all flimsy.

The lids are plastic. I never thought to look and I threw the packaging away. Did you try emailing the company? I am otherwise very happy with them. Great size.

Plastic. Don't know the kind of plastic (discarded now). Just know I was disappointed with the honey inside.

I am not certain of the exact constitution of the material, but it is "plastic-like". The heating/frothing disc, part of the inside of lid, and the inside bottom of the pitcher all contain a plastic-like material.

The lid is plastic. It's sturdy and fits tightly but fairly flexible and not difficult to pop off when you want/need to.

It is plastic. As you can see, most of the electric kettle's lids are made of special plastic that is okay for high temperature.

The colored part where the food goes is silicone, the clear lid that does not come in contact with the food is plastic. The silicone makes it really easy to get the food out. I am very happy with this product and plan on buying more.
