Stasher's thick silicone and airtight seal makes these bags best for protecting frozen goods from freezer burn. It was easy to press out excess air from the bag, and it stayed that way after a couple of days in the freezer. There was some frost clinging to the bag's insides and the mango, but not as much as the others.
Opt for a heavier foil such as Reynolds Heavy Duty Aluminum Foil because it's thicker and harder to tear if you're stacking or moving things around. As an extra line of defense against freezer burn, you can first use a layer of plastic wrap before covering with foil.
Have you considered reusable silicone storage bags? They are a great alternative to plastic bags and can be safely used for freezing soups and pastas without the risk of melting.
Stainless steel shouldn't crack, but it will definitely freeze to your hands when you take it out. I just use whatever plastic tupperware-type containers I have, which haven't cracked yet. Plastic is probably your best bet, and should be pretty easy to find secondhand if you don't want to buy a whole bunch of new ones.
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.

Silicone is far and away a superior material to traditional plastic baggies when it comes to packing snacks and storing leftovers in the fridge or freezer. And these OXO products are made from LFGB-certified silicone, which means they meet the highest of safety standards.
Beeswax wraps are non-plastic freezer bags that are waterproof, reusable and an eco-friendly alternative to clingfilm and tupperware. They even break down in your home compost bin! Silicone may be a loose relative of plastic, but it's a lot more reusable (and therefore sustainable).
Reusable silicone bags for food storage are perfect for storing and freezing meat, fruits, vegetables and more.
Plus, they're safe to store in the freezer. Just keep these safety tips in mind: Always keep the seal partially open when cooking in the oven or microwave. Put your bags and bowls on a baking sheet when cooking in the oven.
Though silicone is technically a plastic polymer, its durable molecular structure keeps it from shedding microplastics in the way that common plastics do. But it can still break apart into small pieces and enter our waterways.
Common Causes of Freezer Burn
Improper Packaging: The biggest culprit is exposure to air. If food is not sealed correctly in air-tight packaging, moisture can escape and air can seep in, leading to freezer burn.
The best containers for freezing food
The key to ensuring your food tastes great after it's thawed is how you store it: Food stays freshest when it's frozen in airtight containers and thick, durable wrappings.
Paper: For 2-3 weeks, paper will do the trick. Butcher paper is a great first layer and waxed paper is even better. Throw a little freezer tape on there to keep it extra-air tight.
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.
Place the wrapped meat inside a bag or container.
We like reusable silicone bags or glass food storage containers. The important thing here is to minimize the amount of air in the bag or container as much as possible, as this will help to prevent freezer burn.

Because it's better for you and the environment. Silicone is highly durable yet lightweight, and holds up from freezer to microwave, oven, and dishwasher without leaching chemicals.
Prevents Freezer Burn: For businesses that rely on frozen food storage, cling film is a lifesaver. It creates a protective layer that prevents freezer burn, which occurs when moisture within the food crystallizes. Freezer burn can degrade the quality of frozen items and lead to food wastage.
Wrap food in plastic wrap or aluminum foil before putting it in your container or freezer bag. Only use plastic wrap, waxed paper and aluminum foil if you are also using a container or freezer bag. None of these, on their own, will keep enough air out to prevent freezer burn.
The flexible silicone material makes it easy to pop out the portions when you're ready to use them. Additionally, you can use it for more than just baby food. As your baby grows, you can use it as a snack tray for older children, or even to freeze individual portions of soup or other foods for yourself.
Look for BPA-free plastic containers with snap-on lids or silicone options that stay flexible even in freezing temperatures. Resealable freezer bags with double-lock zippers are also great for saving space while keeping air out. (Fill them as full as possible, then gently press them to remove as much air as possible.)
FOR STORING LEFTOVERS IN THE FRIDGE & FREEZER: GLASS
For storing food in the fridge or freezer, glass, particularly OXO's set wins. The containers are freezer-safe so the glass won't break, leakproof with a tight seal (no mysterious liquids sticking to your refrigerator shelves!), and easy to clean.
