I like to chop a bunch of onions all at the same time, portion them into zip-type bags and then store them in the freezer for convenient use later.
And that created a problem. Freezing onions in sandwich-weight bags doesn’t seal in the strong onion odor.
However, bags designed for the freezer—freezer-weight zip-type bags—do a great job of keeping food odors from escaping. Who wants their freezer to smell like onions. Or fish or garlic? No one! And apparently that’s the reason someone invented something known as a zip-type freezer bag. Tina
