Not only have they withstood pressure cooking but not one thing I’ve used them on has gotten any contamination. They come nicely packaged and in clean condition, they do have a very strong glue smell but it goes away after a few days , not complaining about it , smell is a small price to pay for strong air tight seal these stickers have . Excellent product 👍
