As such, Ziploc bags are alleged to be "fundamentally unfit for microwave and freezer use" despite their labeling, which has been "leading consumers to believe they are fit to be microwaved and frozen without risk of microplastics leaching into their food." Consumers may have "unwittingly exposed themselves and their families to undisclosed microplastics during routine kitchen practices," per the filing.

As the Ziploc lawsuit asserts, even consumers doing their best to avoid exposure to microplastics can be lulled into a "false sense of security" by purportedly misleading labels.
