Question: Do the plastic liners contain BPA?
Document: I love my crock pot for the ease of cooking in it, but I've always hated cleaning it out. Just a few months ago I was lamenting to a friend about this dilemma, and she told me about crock pot liners. Why did it take me so long to learn about these? They are amazing! Cleanup is so much easier. There are no melted bits of plastic wrap in my food, which I was worried about.
I have been using these liners with my old crock pot for months. I've never had any leaks or tears in the plastic. Even when there is a little left in the bag (too little for me to bother with trying to save) the liner still came out easily. I used them in everything I made (even some bread I make in my crock pot).
I can't say enough good about this product. I was out of them when I used my crockpot a couple days ago and the crockpot is still soaking in my sink. When I use these liners there is absolutely no cleaning of the crockpot that needs to be done. I've never had an issue with a plastic taste or leaking. I ordered two boxes so I'm sure not to run out. Love these!
Fits my 8.5 quart cooker, no plastic oders or food tastes, they make clean up very easy and fast !! !
The plastic is plenty durable not to melt or tear. Final note:  These are ridiculously over-priced on Amazon. Our favorite local retailer &#8211;the one with the bullseye logo &#8211;sells them for $.49 each.
As an avid crock pot user, I always dreaded cleaning the pot after cooking a meal. These bags work perfectly and will never go without them again. use care with knives and forks as the plastic can be punctured. That is expected, but have found the bags to be exceptionally strudy.
What a great product! Read about these and thought there were too good to be true -- not too good, too great and true!You just put the plastic liner bag in the crock of your slow cooker, add the food, put the lind on and cook as usual. Throw the bag away after you remove the food! Easy, peasy.Only caution, be careful not to puncture the bag when removing the food because then all the juice/sauce leaks into hot crock.
These bags are a life saver in the crock pot. Once you use them you will wonder ....why didn't I think of that! When I finish cooking my Slow cooker meal, serve often right out of the pot family style and then pick up the bag with left overs and set it right into a large plastic storage container to stow in the fridge. Then the left overs container is easy to clean too. It just doesn't  get any easier than that!
I really love this product!! I mean who would not? Clean up is a cinch!! I and others have noticed a plastic taste in what we have cooked. It kinda bugs me. I'm not the only crock potter that has noticed this. So, I love this for the easy clean up with a plastic taste to our food. I think I may just go back to the old fashioned way and scrub the crock for good food. Oxymoron I know. See for yourself.
The box felt mostly empty and that's because, well, it was. I had to do a double take to notice that, yes, it was only supposed to contain just the 4 bags. For an avid slow cooker fan, that's not going to last even a week.As a last note, my box seemed to have been involved in some minor glitch on the packaging line.
Answer: No they do not.
