I hate seran wrap with a passion. It clings to everything, including itself. And, for some reason or another, I just can't seem to get it to cover the food or container I'm working with, without taking forever to uncling it from itself!
So, I thought I would give this press n seal stuff a try.
One side of the wrap has no sticky part, the other side is the cling side. Because of this, it clings to itself MUCH less often than seran wrap. It's a LOT easier for me to work with.
You place it over the food/container, and press it against the container, or fold it over the food and press it against itself, to seal.
I wouldn't try doing what they do on the commercials, pressing it against a container and dumping the container upside down, hoping the food won't be heavy enough to rip the wrap away from the container. But, other than that, it does what it says it does, and keeps your food nice, without the nuisance of seran wrap.
