There is one important difference that sets them apart: thickness. While they often look and feel pretty similar to other plastic storage bags, freezer bags are slightly thicker than regular zip-top bags. This translates into a storage bag that's sturdier and even more durable.
Ziploc® brand bags and Endurables® are designed to meet all FDA requirements. Our Ziploc® products are suitable for food contact use for microwave defrosting and reheating, room temperature, refrigeration, and freezing.
Freezing food and vegetables in plastic bags can be safe and effective, but there are some considerations to keep in mind: Pros: Convenience: Plastic bags are lightweight, easy to seal, and take up less space in the freezer.
Freezer bags are thicker, and they're designed to be less brittle than regular bags when frozen, so they're less likely to puncture or tear while you rummage around. (Another advantage is that you can wash and reuse them for longer before they go kaput.)
At any rate, people should feel free to use Ziplocs for SV at lower temperatures (170F and below). They're made from low-density polyethylene, which is about as safe as food-safe plastics get. The freezer bags are preferable, since they're thicker and are designed to minimize gas exchange.

The experts over at Ziploc told me that their freezer bags “are designed to protect in very low temperatures and harsh environments against punctures and tears.” So, in other words, while you can use a normal Ziploc bag to freeze food, chances are it won't escape the clutches of freezer burn and will be more prone to ...
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 get out. Rigid containers are often reuseable and make the stacking of foods in the freezer easier.
This is the result of water molecules within the food freezing, accelerated by the contact with the air. These frozen water molecules can rise to the surface over time, where they gather as crystals. If your frozen food is covered in ice crystals, then this is a clear sign of freezer burn.
What's the difference between freezer bags and non-freezer bags? In short, freezer bags are thicker. How much thicker varies by brand, but Ziploc freezer bags are about twice as thick as non-freezer bags. This added thickness is supposed to help prevent tears and punctures, but it also increases the cost.
If you are freezing food for a shorter period of time (2-3 weeks at most), you can wrap in unbleached butcher paper or waxed paper sheets or bags. Butcher paper doesn't seal the food as well as waxed paper, but it makes a good first-layer wrap. Double or triple for longer freezing periods.
You can choose among parchment paper, wax paper, and Reynolds Kitchens® Freezer Paper when storing food items in the freezer. You may use all three to wrap and separate foods to keep them from sticking together, for example, storing burger patties, meats, or individual servings of leftovers.
Choose from Ziploc Freezer Bags Gallon, which are available in supermarkets, or LK 10” x 12” Gallon Heavy Weight Seal Top Freezer Bags (4 mil), which are designed for food service and available in bulk online. In reusable bags, we recommend (re)zip Gallon Bag 4-Pack and Ello Reusable Gallon Storage Bags, set of 2.
"You can put the chicken in a Ziploc freezer bag, submerge the bag in water, press out any air right above the meat in the bag, then seal and freeze," says Boyd. Maintaining freshness isn't the only reason to remove all air from your storage container.
Wrap Your Meat When Freezing
While a vacuum-sealer is ideal for ensuring that meats are packaged correctly, you can get by just fine with double wrapping cuts of meat with freezer paper, aluminum foil or airtight zip-loc bags.
If there are small ice crystals, this shows that the food has lost its moisture. If the ice crystals are very large, this may indicate that the meat has thawed and refrozen, meaning that it is likely to spoil. Use your best judgment to determine whether you want to eat something.
Freezer frosting is the build-up of frost on the walls and shelves inside a freezer. This can happen when there are fluctuations in temperature or when too much moisture gets into the freezer. The frost can also be caused by air coming into the freezer, which brings humidity and causes it to freeze.
Keep your appliances at the proper temperatures.
Keep the refrigerator temperature at or below 40° F (4° C). The freezer temperature should be 0° F (-18° C). Check temperatures periodically.
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.
Plastic, aka the Best Storage Containers to Keep Bugs Out
Plastic storage boxes are the best storage containers to keep bugs out. They provide the best protection because pests won't be able to chew through or rip them open. Plus, they're easily stackable and much better at protecting your stored items from damage!
Whether they are marketed for the freezer or general storage, all bags are made from the same material: polyethylene. The thickness of the polyethylene film is what differentiates a freezer bag from a regular zipper lock bag. In general, the thicker the bag, the less likely it is to allow moisture and odors in or out.
It's not possible to reverse freezer burn, but you may be able to minimize its impact with a few basic practices. If you can, trim away visibly freezer-burned portions of meats prior to cooking and add flavor by marinating or seasoning dishes to taste.
Use the Right Gear: You must use containers, bags and wraps designed for the freezer. These are thick enough to keep moisture in and freezer odors out. Even when you double up regular sandwich bags or plastic wrap, they are simply not thick enough to do the job.
