Make sure your food storage supplies are fresh and up to date using these 2" x 3" food rotation labels. These labels let you clearly name and date prepared contents in food pans and storage containers, helping maintain the FIFO (First In, First Out) system. When you want to get these labels off, just run the container they're on through a dishwasher or under hot or cold water for 30 seconds - they're completely dissolvable and biodegradable, with no sticky residue left behind. They're also for all sewer and septic systems, won't clog drains, and are for use in microwaves and freezers, too.
