This item is made of materials that are safe for freezer use. Please note that plastics are less flexible when cold or frozen and may break if dropped. Also note that water expands when frozen, so when filled to capacity the container could expand outwards.
Safe to use in the microwave, freezer and dishwasher, the TakeAlongs™ lid design allows you to worry about one less thing. If you hear the click, you know your seal is secure. To keep your new containers performing at their best, please read the following: Remove label and wash before use.
- Plastic: High-density polyethylene (HDPE) and polypropylene (PP) are generally safe. Avoid thin, flimsy plastics. - Silicone: Food-grade silicone is typically freezer safe. Labeling: Check for any labels or symbols indicating that the container is freezer safe. Many manufacturers will specify this on the packaging.
Only put plastics in the freezer if they have a freezer-safe label. Single use containers, such as ice cream or milk cartons, should be avoided for freezer use. According to MSU Extension, use containers in the freezer that are moisture-vapor resistant, leak proof, and easy to seal.
Rubbermaid's polycarbonate can handle temperatures from -40 to 212 degrees Fahrenheit and is dishwasher-safe.

Matters on what Rubbermaid container. They make a lot of different containers out of different materials. Their food storage containers can handle temps up to about 212F, the large utility containers will not melt until around 240F but will soften and warp at much lower temperatures, so is not safe to sous vide in.
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.
LDPE — Low density polyethylene plastics are listed as the number 4 on the triangle code. They are used for a wide range of items such as dry-cleaning bags, bread and frozen food bags and squeezable bottles for mustard and honey.
A: No. There are a lot of plastic containers and bags specifically for use in food storage, including freezing. Meat in trays and commercial plastic wrap can be safely frozen as they are, but make sure you thaw meat at a cool temperature.
If you fill a plastic water bottle completely with water and leave it in the freezer, the expansion of the freezing water can put immense pressure on the bottle. Over time, this pressure may cause the bottle to deform, crack, or worse, explode.
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.
The key to preventing freezer burn is to keep air outside your storage containers. Most frozen food is packaged in freezer-friendly boxes, but it doesn't hurt to put the whole thing in a second plastic zip bag (after you squeezed all the surplus air out first, of course).
Constructed from durable, BPA-free plastic, these food containers are built to withstand a wide range of temperatures and are dishwasher, microwave, and freezer safe.
I use the freezer bags, but also use the rubber maid. If you put it in the frig to thaw the lids don't often break, but you need to let it thaw first, also I get mine at dollar tree that come in two or three packs, so it's ok just to throw them out after they crack.
Freeze Safe Symbol: The freeze safe symbol, usually depicting a snowflake or a snowflake inside a triangle, indicates that the plastic container is suitable for freezing food items.
Snowflake-looking symbol? That'll mean that the container is freezer safe. Look for this symbol when you're thinking of storing some delicious leftovers in the freezer (stew, soup and more). For meal-prep buffs, this should be the symbol to look out for!
Mostly Myth. Freezing food in plastic containers generally poses a low risk of chemical leaching, especially when using containers designed for freezer use. The stability of plastic at low temperatures minimizes the release of potentially harmful chemicals.
High impact polystyrene (HIPS) · PS HG1 C5
It is particularly suitable for refrigeration products that need to be resistance to Cyclopentane or other HCFC's.
General Usage: Rubbermaid Glass can be used for storing and heating food. Glassware is freezer, refrigerator, and microwave safe. Use glassware for warming and reheating food in microwave oven and in preheated oven.
A: Yes you can freeze rubbermaid with vented lids.
While there is no set timeframe for replacing plastic food containers, experts say they should be tossed out when they show visible wear, chips, cracks, or signs of stains and odors. In place of plastic containers, experts recommend opting for glass or stainless steel instead.
Rubbermaid uses a clear plastic for the containers that suffers from cracks. This was put in the top of the dishwasher, and cracked in two places. The lids are amazingly good, but the clear plastic is likely damaged from heat on a dishwasher environment.
