The best freezer storage containers depend on what you are freezing. For everyday meal prep and leftovers, Rubbermaid Brilliance (both glass and plastic) are top overall picks. For portioning soups and sauces, Souper Cubes are the ultimate silicone solution, while DuraHome Deli Containers provide budget-friendly versatility.
The best freezer containers depend on your storage style, but clear glass and heavy-duty silicone top the list for durability, safety, and stain resistance. Here are the top-rated options for 2026:
Freezer burn is primarily caused by air exposure and moisture loss. The best containers to prevent it are those that create an airtight and vapor-proof seal.
Freezing temperatures do not damage glass food storage containers the way they do plastic. This makes them a superior choice for storing frozen food. While glass can handle freezing and hot temperatures, it's not a great conductor of heat. If you put hot glass into cold water, or vice versa, the surface will contract.
The best freezer containers for meal prep depend on your specific needs, but the top overall performers for freezing, storing, and reheating are highlighted below:
The safest materials to freeze food in are glass, food-grade silicone, and stainless steel. These options are non-toxic, free of harmful chemicals (like BPA, phthalates, and microplastics), and do not leach into food during the freezing or thawing process.
The best Ziploc alternatives for the freezer are reusable silicone bags (like Stasher) or PEVA bags (like (re)zip) for a flexible, space-saving option. For rigid, zero-plastic, and odor-proof storage, use tempered glass containers with snap-locking lids.
Using plastic for freezing food isn't inherently dangerous, but it comes with caveats. It is generally safe if you use rigid containers explicitly labeled as "freezer-safe" and avoid microwaving food directly in them.
Putting a penny (or any coin) in the freezer is an easy trick used to check if your freezer lost power while you were away, and whether your frozen food is still safe to eat.
You can freeze food without plastic by using glass containers or stainless steel cans. Ice cube trays are a great option for smaller portions. If you want to freeze food without using any packaging at all, you can place suitable items of fruit or vegetables in their natural peel directly into the freezer as they are.
Depending on your budget and the type of food, you can use freezer bags, freezer-ready plastic containers, freezer-safe glass or a sealed vacuum bag.
Yes, according to class-action lawsuits and consumer advocacy groups, Ziploc bags can release microplastics when frozen.
The best non-plastic freezer containers depend on your storage needs: Borosilicate glass (for stews and leftovers), Stainless steel (for durability and non-microwavable meals), and Food-grade silicone (for pre-portioned soups). These options prevent freezer burn and keep harmful chemicals out of your food.
Yes, plastic can leach chemicals and shed tiny particles into food when frozen. Extreme cold can make the material brittle, causing it to degrade under stress and release microplastics and chemicals (like phthalates) into your food.
Glass. Glass is strong, chemically inert, and the best material for freeze long-term storage. Tempered and borosilicate glasses are best, as they do not shatter with thermal shock. While airtight lids are great for keeping out freezer burn, glass containers aren't flexible.
The Amish refrigerate their food without relying on standard electrical power grids, instead using a blend of traditional, off-grid, and modern technologies. Methods include gas-powered refrigerators, traditional ice houses, and naturally cool underground spaces.
No, freezing does not kill E. coli. Instead, it pauses bacterial growth. While some bacteria may die off in the freezing process, many survive and will begin multiplying again as soon as the food thaws.
Non-profit organisation Love Food, Hate Waste recommends the 2:2:2 rule. Two hours to get them in the fridge. Two days to eat them once they're in there. Or freeze them for up to two months.
The safest containers to freeze food in are made of tempered/borosilicate glass, food-grade silicone, or stainless steel. These materials are inert, meaning they won't leach chemicals (like BPA or phthalates) into your food, absorb odors, or degrade over time in cold temperatures.
No, it is not safe or recommended to use 40-year-old Tupperware (from the 1980s) to store food. Older plastics degrade over time, posing significant health risks.
It's hard to avoid microplastics entirely, but knowing where the highest levels come from can help you limit your exposure.
The healthiest way to freeze food is to use non-toxic, airtight containers like glass, stainless steel, or high-quality silicone to prevent freezer burn and chemical leaching. Cool food completely before freezing, pack it tightly to remove air, and use glass Mason jars for liquids to ensure a safe, sustainable, and nutrient-dense way to preserve meals.
A quality reusable silicone bag might run several times the price of a pack of Ziploc bags. But because they last so long, using silicone bags leads to long term savings. Ziploc bags are cheap initially but add up if you frequently buy replacements. Plus, the environmental costs aren't reflected in the price.
The best approach for freezing meat is the double-wrap method: tightly seal the meat in plastic wrap to remove all air, then wrap it in a layer of freezer or butcher paper. This creates an impenetrable barrier against air and moisture, completely preventing freezer burn.
