its a plastic liner...

Makes clean up a breeze

First of all these are great liners. I use them all the time in my crock pots. It makes clean up a breeze just rinse out the crock when your done, no heavy scrubbing needed. The problem I had was with Sam's shipping. They didn't pack the box properly with the other items being shipped and the liner box was broke open when it arrived and the liners were loose in the cardboard box.

I don’t know what happened to these liners, but they are horrible. I used them years ago, and the were great. But now, they ALWAYS leak. They also melted to the side of my slow cooker. I won’t be buying these anymore. If I could give them 0 stars I would.

Package opened , 20 not 24 present

Ordered three boxes and the all three arrived in crushwd and open boxes.

Cooking bag are good I am sure, however did not fit in my cooker. My fault

I have been using these liners since I found them. When raising my family, working 2 jobs, and attending nursing school, these liners were imperative! They also fit my ceramic roaster, which holds an 18 lb. turkey. They made my life so much easier! I gift these at Christmas and birthdays. Everyone looks forward to receiving them, along with the basket of other household essential supplies.

At only around a quarter for each liner, these are a MUST! I used to scrub down my crockpot for years, wish I had used these much much sooner!!

I bought these because I was tired of scrubbing out my crock pots. I used one and it leaked. I used another one and it not only leaked but started melting. Crock pot was set on low. Couldn't even eat my baked beans.
