Great bags. It has a foldable top to seal. The glue is better on these than the other * emoji bags. I like rolling down the paper sack compared to the plastic twist.

The lock mechanism is both spill proof and smell proof. They close up securely to keep the contents confined. They seem to hold in the liquid without it soaking through.

Purchased to keep in my uber after 1 rider vomited in my car. When i see a passenger is about to get sick i give him or her a sick bag and they are very appreciated is saves me time and money specially on a friday or saturday night.

These bags are as thin, and maybe thinner, than paper lunch sacks. They are not leak proof and they are not lined with polyethylene. If you are looking for a bag where you can wait awhile to dispose of it, this is not the one.
