Slider storage bags can be used in the freezer. They are designed to be freezer-safe and can withstand the low temperatures of the freezer without cracking or leaking.
When using slider storage bags in the freezer, make sure to fill them only to the recommended level, leaving some space for the contents to expand as they freeze.
Label the slider storage bags with the contents and date so that you can easily identify them later. It's also a good idea to stack the slider storage bags flat in the freezer to save space and allow for more even freezing.
