The reason for this is, reusable silicone bags are airtight; this helps prevent your food from getting freezer burn. Silicone bags are also treated to withstand extremely low temperatures to very high temperatures, which makes them more durable than PEVA bags.
Wax freezer paper and butcher paper are more effective than conventional plastic wrap. "Wrapping your item tightly in waxed freezer paper can act as a barrier against the harsh air inside the freezer and can also prevent water from evaporating," says Pace.
It's safe to store food, put in the microwave, freezer, oven, and dishwasher. You can even cook right in your Stasher bag, sous vide style. It won't leak, break down, or degrade over time.
Silicone is more eco-friendly than single-use plastic because it doesn't break down into tiny pieces like plastic, making it better for our oceans and waterways. Plus, it's more reusable than flimsy or single-use plastic, which can help us keep more slow-to-degrade materials from the landfill.
Protect your food with Ziploc® brand Freezer Bags. Each bag locks out freezer burn while keeping food fresh and full of taste. Less freezer burn means less wasted food and money.
What causes freezer burn? Improper packaging or temperature, and sometimes too long in the freezer, are the most common culprits that lead to freezer burn. Cold, dry air is more likely to permeate foods that aren't tightly wrapped, left open or stored in frequently fluctuating temperatures.
Freezer bags, which range in size from a pint to two gallons, can be used in all the same ways you'd use any other type of zip-top storage bag. The opposite is also true: You can use regular zip-top storage bags in the freezer — I'll admit that I have from time to time.
Rigid containers and flexible bags or wrapping are two general types of packaging materials that are safe for freezing. Rigid containers made of plastic or glass are suitable for all packs and are especially good for liquid packs. Straight sides on rigid containers make the frozen food much easier to remove.
Silicone, which is made from silica found in sand, is much longer lasting than plastic in the environment as well as while being used in products. Silicone endures extreme fluctuations in temperatures - from very cold to oven hot - without melting, cracking or otherwise degrading.
You can boil them, pour boiling water into them, microwave them, put them in the dishwasher, freeze them, you name it. The seal at the top is watertight so you don't have to worry about spills or contents getting soggy in the rain and because they're made from the highest grade silicone, they'll last for years.
Most silicone items are supposed to last you 10-20 years if you take proper care of them. Once they reach their end of life, it is best to be recycled. You can do it at home or send it to a recycling center.
Stasher bags are made of all food-grade silicone, and are odorless. As a result of the higher quality product used for the bag, that also results in a higher priced bag (and according to online reviews on Amazon for similar products, they are also a lot higher quality when it comes to the zipper seal function as well).
Anything liquid in a sealed glass container or can could explode. It's no secret that liquids expand and contrast when placed in the freezer. For this reason, Murphy recommends avoiding placing glass containers full of liquids in the freezer. The same logic applies to cans and even plastic storage containers.
Fill a large bowl or plastic tub with water, take your labeled freezer bag and seal it three quarters of the way. Push the bottom of the bag into the water and the air will push itself out. Submerge the bag stopping just shy of the unsealed portion and then seal it just above the water. We all do it.
Zip-top bags are especially good for freezing food because you can more easily get all the air out of them than out of rigid containers. You can use them for everything from blanched spinach to chicken thighs and, after laying them flat to freeze, stack them to economize space.
Plastic containers can release chemicals when frozen just as they can when heated. For better food safety, opt for glass. The right glass containers are freezer and refrigerator safe, meaning they won't release any harsh chemicals or break if frozen.
Flexible Bags or Wrappings
Flexible freezer bags and moisture-vapor resistant wrapping materials such as plastic freezer wrap, freezer paper and heavy-weight aluminum foil are suitable for dry packed products with little or no liquid. Bags and wraps work well for foods with irregular shapes.
On the one hand, this backbone of siloxane bonds gives silicone its low thermal conductivity, resulting in an extremely heat resistant and thermally stable material. On the other hand, whilst stable and flexible, silicone's chain is weak, which means it tears easily.
In short: They're worth splurging on, especially if you find yourself using the plastic version frequently, and using silicone bags makes for a more eco-friendly kitchen.
Silicone doesn't turn into micro plastic when lost in the environment. So, is silicone safe? Yes! Silicone is also extremely durable and significantly more ocean-friendly than plastic since it doesn't break down when lost in the environment into micro pieces like plastic does.
Freeze Food in Stainless Steel Containers
Like glass containers, metal containers can also be reused over and over again. They are a great solution for those who want to freeze food without plastic. Freeze fruit on trays before transferring to containers to avoid creating clumpy frozen blobs.
Aluminum Foil: Aluminum foil can be reused and is a great way to preserve food in the freezer! Just make sure to wrap it tightly to avoid holes for air to get in and you can also seal up with freezer tape to keep things extra-secure!
Buy meat in bulk, then cut into individual portions. Separate each portion in a Ziploc® brand Perfect Portions bag, then place all the individually wrapped pieces in a Ziploc® brand Freezer bag with the Smart Zip® Seal and freeze.
