Can I freeze stainless steel? For lunchboxes, yes! Just make sure you leave a gap between the food and the lid as it will expand.
Stainless steel is highly resilient to temperature changes. It can safely go from the freezer to the oven without any issues. This versatility is especially useful for meal prepping and storing a variety of foods.
Yes, you can put a stainless-steel container in the freezer. Stainless steel is a material that can withstand extreme temperatures, both high and very low, and it can withstand freezing very well, with no risk of the stainless-steel dish cracking, breaking or warping when placed in the freezer.
Stainless steel is non-staining and non-porous. These containers are refrigerator safe, making them a great option for leftovers or lunches. A metal pan cooled down to normal room temperature can be put into the fridge without damaging it.
Room can be left in containers to account for this expansion but it is not always able to prevent damage to a container. Polypropylene and PVC are both plastics that are brittle at temperatures below freezing. Polystyrene is considered brittle at 68°F and is very brittle at temperatures below freezing.
Stainless steel containers also withstand freezer temperatures, are endlessly reusable, and won't leave an odor or flavor.
Glass containers can break due to expansion when frozen, while plastic containers may become brittle and crack. Steel containers are generally not recommended for freezing as they can cause freezer burn. Look for containers specifically labeled as safe for freezing.
Even with these impressive features, stainless steel can and does rust after all, it's 'stainless' not 'stainfree'. Some types of stainless steel are more prone to corrosion than others, depending on the chromium content. The higher the chromium content, the less likely the metal will rust.

Climate-controlled storage – When subjected to extreme humidity, stainless steel can suffer from rusting. Therefore, it's important to store the material in a climate-controlled setting to prevent moisture build-up. You might use dehumidifiers in storage areas to maintain optimal conditions.
FDA Food-Safe Stainless Steel with plastic lid. Hand wash only. Use for cold beverages only. Do not use in dishwasher, microwave, conventional oven, or freezer.
Stainless Steel – Many experts agree that stainless steel water bottles are the healthiest choice. Unlike plastic, they are highly sustainable and eco-friendly because of the longevity of the material. They also offer other benefits, such as being free from harmful chemicals and toxins.
Food grade materials, such as aluminum foil, heavy freezer-weight plastic bags, heavy plastic wrap and parchment or freezer paper are excellent choices. It is safe to freeze meat or poultry directly in its supermarket wrapping, but this type of wrap is thin and lets air in.
Due to its chromium and nickel content, grade 330 stainless steel can confidently endure temperatures up to 2,000 degrees Fahrenheit. However, for the greatest lifespan, it's recommended only to expose grade 330 alloys to a maximum heat of 1,900 degrees Fahrenheit.
Do not put your stainless steel water bottle in the freezer especially if has liquid inside. First of all, the water inside will not be as cold as you want it to be because of the bottle's insulation. Also, the high temperature in the freezer can cause damage, like dents, on the surface of your water bottle.
Avoid Acidic Foods for Long Periods: Though stainless steel is resistant to corrosion, storing acidic foods (like tomatoes or citrus) for extended periods may cause minor discoloration or pitting over time.
After testing dozens of sets for our guide to the best food storage containers, we recommend the Pyrex 18-Piece Simply Store Food Storage Set. These durable tempered-glass containers stack well and won't pick up stains or smells. They're also safe to use in the oven, as well as in the freezer and dishwasher.
Cold makes metal more brittle.
Metal containers: You will not often find metal containers meant for the fridge. You need to be mindful of what type of metal you use to store food inside the fridge. It is generally recommended to use a 100% stainless steel container to store food if using it as a fridge container.
If you've tried all of the above cleaning methods and your stainless steel cookware is still scratched, stained, dented, or rusted beyond repair. Then you'll want to replace it. This is especially so if your pots and pans have been scratched to where the material beneath is showing.
So the “magnet test” is to take a magnet to your stainless steel cookware, and if it sticks, it's “safe”—indicating no nickel present—but if it doesn't stick, then it's not safe, and contains nickel (which is an austenite steel).
If harder stains or rust remains, sprinkle baking soda or another non-abrasive scrub cleaner on a soft, damp cleaning cloth, mixed with liquid soap. Clean problem areas gently, going with the grain of the stainless steel. Spray the surface with vinegar-water mixture or glass cleaner and wipe again. Pat dry.
Ziploc® Containers with lids feature easy-to-use, leakproof Smart Snap technology. They are BPA free and safe for use in the microwave, dishwasher, freezer and fridge (when used as directed). Use them to store food, organize supplies, or while on the go.
Freeze Safe Symbol: The freeze safe symbol, usually depicting a snowflake or a snowflake inside a triangle, indicates that the plastic container is suitable for freezing food items.
We like glass for its durability and ability to resist staining and scratching. It's also more commonly dishwasher safe than plastic containers. In addition, some glass containers are safe to transfer directly from the freezer to the microwave or even the oven (though be sure to remove the lid).
