Question: Are the liners BPA  free ?
Document: A great invention! Keeps your crockpot free of baked-on food making it very easy to wash. I bought the bags to accompany a gift crockpot and both were enthusiastically received.
I have a crockpot that I purchased about 2 years ago. It has a stick-free interior. It is a great crockpot except that the stick-free interior is flaking off into my food. That's not so great. So I bought these & am able to use the crockpot again without the added bonus of the interior of the crockpot in my food & clean-up is really a breeze.
these liners save a ton of work , no leaks or tears. no sticking to the bottom or sides of the pot
very easy clean up when you use these liners! just toss- so much easier to wash off without a mess or fuss.
the liners keep the crockpot clean with no scrubbing after leaving meals simmering for a long time. there is no other way to go.
Purchased a crockpot for may daughter and included the liners. She tells me they work great. Really helps with the cleanup
I have used these liners for a year or so, now, and love them. Such easy clean up!!! I whole-heartedly endorse this product.
I love these liners. I use them  all the time in my crock pot. They really save on clean-up. What a great idea! !
Product looks much bigger on line. Does not tell you it has only 4 liners in box. Would not recommend to a friend. Debora Makower
If you love your crock-pot, but hate cleaning it, these liners are perfect for you! They're easy to use and easy to dispose - I love them!
