What are these made of? Food grade silicone, BPA free, etc?

They are definitely not silicone. I am pretty sure they are polypropylene or LDPE. There is no identifying code on the bottom of the bottle, but there is a '5' on the inside of the cap. The look and feel is consistent with lab wash bottles made of those materials (I used to be a Chemist)

In my research i have found answers of silicon and bpa free stated on other web sites. Hope this helps.

They are either silicon, or silicon-like. Whatever they are made of, they are incredibly pliable, do not dry out , and work extremely well.

I would say that they are silicone. They feel like it. It's VERY flexible - so much so that I should have a thin board to rest underneath them as I put them in the freezer.

They feel as though they are all silicone and state in the paperwork they are completely coated in silicone. There is one item that has a metal core but the rest are microwave safe as well! I really enjoy this product- I have had mine for about a week.

The packaging does not say BPA free, but it does say that it is 100% FDA grade silicone.

I would suggest contacting Norpro to be sure but I assume as it is silicone it is bpa free to be food safe.

I believe they are silicone. My son is slightly allergic to latex and he hasn't reacted to these bands at all.

Hi, thank you for reaching out! You can be sure they are certified BPA free. On the LittleBigBox's box we printed a small icon that says so, and we'll be including more information on the inner labels to make it clearer for our customers that our products are safe for storing and heating food. We believe in ethics and honesty and wouldn't advertise characteristics that we cannot backup or that are untrue and specially harmful for our customers. I hope I've been able to answer your question and feel free to reach out again in case you have any other doubts or comments!Thank you

I do not see anything on the label that indicates what the bags are made out of since they are not used for food. Many food bags now state that they are BPA free but I am unaware of any concerns with pvc. You can contact the manufacturer at http://nancysilver.com. The label claims that this is the same technology used by NASA, The Guggenheim Museum and jewelry manufactures worldwide and they have worked for me!

Plastic....BPA free... I really enjoy using them, especially with the lunch bag designed for them. Very flexible, lots of options. Other questions? Post, and I'll get back to you.

The container says "high grade silicone" but it doesn't list all the ingredients or specifically say BPA-free.

Food grade silicones are generally platinum based materials. All purpose silicones are usually tin based. Food grade silicones are tested to ensure they will not leach potentially toxic materials into your food. Thank you.

They are food grade silicone, oven safe to 475 degrees/ 250 Centigrade, freezer and microwave safe. I love them. I even use them for molds for my cold process soap making. They hold up beautifully.

I don't believe these are BPA free but I'm not 100% sure. I bought them as party favors for my kids birthday party and they're cute but certainly made of flimsy plastic

I don't have the packaging any more so I can't say for certain if it said BPA free, but the way I understand it BPA is a plastic based issue and these mats are food grade silicone, not plastic.

They're plastic, but they're BFA free, I believe. They do great in the dishwasher.
