The ultimate packaging to avoid freezer burn is a vacuum-sealed bag. By extracting all the air and creating an impenetrable, tight seal, it prevents moisture from evaporating out of the food.
Choosing the right materials for freezer storage is essential. High-barrier materials like multilayer films, vacuum-seal bags, and heavy-duty aluminum foil offer superior protection against air and moisture.
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.
For long-term freezing, overwrap the porous store plastic with aluminum foil, freezer paper, or freezer-weight plastic wrap or bags to prevent "freezer burn." Be sure to seal the secondary packaging well to keep air out and moisture in.
To effectively prevent freezer burn, you need bags that block oxygen and subzero moisture. The best bags depend on your budget and equipment:
The safest and most practical alternatives to Ziploc bags are reusable food-grade silicone bags (like Stasher) and compostable plant-based bags (like those from Green Paper Products). These options eliminate exposure to toxic chemicals like BPA, BPS, lead, and phthalates found in traditional plastic.
Generally, glass is better for long-term food storage because it is non-porous, doesn't leach chemicals, and won't stain or absorb odors. However, plastic is excellent for convenience and space-saving.
Accordingly, our kitchens must be kashered (“kosherized”). Things that can't be koshered must be put away or (wait for it…) covered. If you visit different houses, you may notice different things covered or uncovered.
The safest freezer containers are made of borosilicate glass, food-grade silicone, or BPA-free plastics explicitly labeled for freezing. These materials resist cracking at sub-zero temperatures, do not leach chemicals into food, and prevent freezer burn.
In most cases, wrapping your food in foil is safe, but it's best to avoid acidic or salty foods that can break down the foil's protective layer, potentially allowing it to react with food. Some of the main offenders are tomatoes and tomato-based dishes, citrus fruits, vinegars and cured or brined meats.
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.
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 alternatives depend on your specific need: reusable silicone bags (like Stasher) are ideal for food storage, organic cotton tote bags are perfect for groceries, and compostable plant-based liners replace trash bags.
Choose vacuum sealers for long-term freezing (up to 1–2 years), bulk meal prep, and sous vide cooking. Choose Ziploc bags for short-term fridge storage, storing snacks, or quick marinating when you need an inexpensive, low-effort option.
The Amish use a combination of historic preservation methods, natural ice harvesting, and off-grid appliances to keep meat cold without standard electricity. Their methods depend on the season and the strictness of their local church rules (Ordnung):
Yes, plastic wrap helps prevent freezer burn, but it cannot do the job alone. Because standard plastic wrap is slightly permeable to air, you should use a "double-wrap" method for maximum protection: tightly wrap your food in plastic wrap, then place it inside a heavy-duty freezer bag or wrap it in aluminum foil.
10 Zero-waste plastic bag alternatives
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.
Aluminum foil can serve as a barrier to prevent external light sources from penetrating the glass. This is particularly useful in the early morning or evening when light can interfere with sleep. In addition, the reflective properties of aluminum foil also contribute to improving privacy.
You will need two sinks in your kosher kitchen, one for meat and one for dairy. Separate sinks for washing dishes and preparing food are recommended. If the two sinks are adjoining, there should be an effective separation between them so that no water or food splashes from one sink to the other.
A mezuzah is a small case affixed to the doorframe of each room in Jewish homes and workplaces which contains a tiny scroll of parchment inscribed with a prayer. It is customary for religious Jews to touch the mezuzah every time they pass through a door and kiss the fingers that touched it.
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.
People freeze water with a penny (or any coin) to check if their freezer lost power and dangerously thawed their food while they were away.
The healthiest containers for storing food are glass, stainless steel, and ceramic. These materials are inert, meaning they won't leach harmful chemicals like BPA, phthalates, or PFAS into your meals—even when exposed to heat.
