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.
TakeAlongs are the best of both worlds: lightweight enough to bring on your office commute or to potlucks and picnics, yet durable enough to hold up to the dishwasher, freezer, and microwave.
Only if it says freezer-safe (usually tempered glass). Otherwise, it can crack and that's no fun. Also make sure to remember that liquids expand, and glass has no wiggle room, so if you're freezing in a freezer-safe glass container, you still want to leave a little room at the top.
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.
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.
“Plastic food storage containers should be replaced every six months to one year, depending on usage and wear and tear. Over time, plastic containers can become scratched, stained, or damaged, and that starts to pose a food safety risk, explains Dragomir Markovic, food scientist and founder of Wise Intake.
Don't use plastic containers that are more than 10 years old. Generally speaking, your containers will tell you when they're ready for their trash can funeral as they develop staining, scratches or odors that won't go away no matter how thoroughly you wash.
Glass containers, in contrast, are toxin-free, easier to clean, and safe for freezing and heating. Choosing glass food storage containers helps reduce exposure to environmental toxins, which is crucial for overall health and reducing the risk of chronic illness.
High-quality plastic shot glasses, especially those labeled freezer-safe, can also be placed in the freezer. These are often used in outdoor settings or for large events where breakable glassware isn't practical.
“You really can't go wrong with trusty Pyrex,” says Ali Rosen, author of Modern Freezer Meals. “They stack great, have multiple colors for easier organization, and are the best value for the quality of any brand.” This set includes a variety of round and rectangular containers that nest nicely for storage.
If a jar is narrow, or has sides that taper inwards, the extra pressure placed on the glass sides as the contents freeze will make it crack (which relieves the stress).
What Are the Best Containers to Use? Glass, plastic and even freezer-safe bags all work perfectly (just make sure the bags are heavy duty). No matter what container you choose, pick something that's airtight.
The short answer is yes—but there are a few rules you should follow. When using Pyrex or any glass bakeware or cookware, you should avoid extreme temperature changes—very cold dishes shouldn't be placed in a hot oven, and vice versa. Sudden changes in temperature may cause the dishes to shatter or break.

A snowflake is probably the most easily recognizable indication of cold, which makes it the perfect symbol to mark freezer safe kitchenware.
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.
Particular types of glass jars and containers are safe to put in the freezer. But not all glass containers are freezer safe. When purchasing glass containers try to choose tempered glass or freezer-safe. This will ensure that your container will remain in one piece when you want to chill your food or drink.
Expansion and Contraction: Plastic expands and contracts with temperature changes. If it's not built to handle this, it might crack over time. Freezer-Safe Plastics: Some plastics are made to be freezer-friendly. They're tougher and less likely to crack.
Unlike plastic, certain glass containers can go from freezer to microwave or oven to table. They're made of a nonporous surface, so they don't absorb smells or stains like plastic containers.
Polyethylene bags, Mylar-type bags, food-grade plastic buckets, glass canning jars, and #10 cans are all suitable for dry sugar storage. Glass canning jars and #10 cans work best for liquid syrups and honey. Removing oxygen for long term sugar and honey storage is not required and not recommended.
Glass may break when subjected to temperatures below freezing. This may occur because the contents freeze and their expansion cause the glass to crack (if the cap does not come off).
Our Ziploc® products are suitable for food contact use for microwave defrosting and reheating, room temperature, refrigeration, and freezing. Remember, it's always important to follow each product's usage instructions. Furthermore, Ziploc® brand products are made in accordance with Good Manufacturing Practices.
Rubbermaid Glass containers are safe for use in ovens up to 425°F and in microwaves without a browning element. They are not for stovetop, broiler or toaster oven use. Lids are not oven safe but are safe for microwave use and are BPA Free.
Even the low levels of BPA that leach from consumer plastics, canned food linings or other consumer goods … have been shown to be associated with harm, and people certainly should care about it. “If it's not safe the day you buy it, it's not safe 10 years later,” Vandenberg said.
Through the Rubbermaid Food Storage Recycling Program, you can easily recycle all brands of food storage containers for free. Even though Rubbermaid has sponsored this program, you can still recycle any brand of plastic or glass food storage containers, like Tupperware, Pyrex, OXO, or even generic brands.
