Airtight Containers - 2 years
Sealed airtight containers are extremely practical for storing food and make excellent lunch boxes. We use them day in and day out. But every now and then, our favorite container might start to show signs of overuse: a lid that closes poorly, a broken hermetic seal, sauce stains, etc. They typically have a lifetime of 2 years, except for the Tupperware brand, which lasts for life. Also, glass varieties are best, not only for the planet but also for secure food storage and safe reheating. So watch your containers for wear and tear, in order to store your food safely.
