Yes, you can put most Glad containers in the freezer, especially those labeled GladWare or FreezerWare, as they are designed to be freezer-safe, microwave-safe, and top-rack dishwasher-safe, but always leave room for liquids to expand to prevent cracking. For best protection against freezer burn, Glad recommends using their specific FreezerWare products.
All Glad products can be used in the freezer, but we recommend using Glad freezer products for the best protection.
Can I put glass in the freezer? 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.
Wavy line = freezing liquids (soups, sauces) to allow safe expansion. Freezer-safe down to -13°F (-25°C).
The Best Place to Store Plastic Wrap
To prevent clinging and static, you should be storing plastic wrap in the freezer!
High Density Polyethylene (HDPE)
HDPE is a durable and stiff resin. It is great for freezing, but not for heating. It is commonly used in industrial settings and is represented by the number 2 and HDPE.
One of the questions we're asked most is whether tortilla wraps can be frozen and we're glad to say the answer is yes!
If your Tupperware container has a snowflake symbol on it, don't worry about freezer damage—that symbol means it's freezer safe. If you don't see the snowflake symbol, avoid putting your new containers in the freezer.
Freezing temperatures do not damage glass food storage containers the way they do plastic. This makes them a superior choice for storing frozen food. While glass can handle freezing and hot temperatures, it's not a great conductor of heat. If you put hot glass into cold water, or vice versa, the surface will contract.
People often freeze liquids in glass jars. It's a common practice. You just need to make sure the product is at least at room temperature or colder and leave about an inch of air surface before sealing.
The safest glassware for both microwave and freezer use is made from borosilicate or tempered glass. Here's why: Borosilicate glass expands less when heated or cooled, making it resistant to cracking. Tempered glass is strengthened to handle sudden temperature shifts, though not as heat-resistant as borosilicate.
Thin or decorative glassware (e.g., wine glasses, crystal, or non-tempered glass) should not be stored in the freezer. These types of glass are not designed to withstand extreme temperatures and may crack or shatter.
In this oven-safe glass container with a leak-proof lid, you can cook, serve, store and freeze all kinds of dishes – and even bring them with you.
Pyrex dishes can safely be used in the freezer, but avoid extreme temperature changes to prevent shattering. Allow hot Pyrex to cool before freezing and defrost slowly before cooking. Avoid placing cold Pyrex in a hot oven or on a hot surface to prevent cracking.
After 4 freeze-thaw cycles, the release of MPs and NPs significantly increased, reaching 450±38.65 MPs and 2.91±0.10 × 108 NPs per liter, respectively.
Plastic is of course more sturdy, and many customers like resealable containers. Glass is less sturdy than plastic, holds way less beverage per pallet, and weighs significantly more. This means we would need to drive more trucks, and that each truck would be more heavily loaded.
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.
High Heat Tolerance
While plastic containers may warp and release chemicals under heat, and metal can react with certain foods, glass remains stable and unchanged. This makes it perfect for everything from reheating meals to storing hot soups and sauces.
Crack Resistant
Securely store food and leftover meals, freezer-burn free. Unlike other plastic containers, Glad FreezerWare was designed to be crack resistant in the freezer, so you can safely go from the freezer to the microwave.
It's a personal choice—glass is more durable and recyclable, but also more expensive. Plastic is typically budget-conscious and lightweight, but it's not exactly sustainable. Whatever your needs are, we tested the best freezer containers for soup, meal prep, and more.
Many disposable plastic containers and food packaging aren't the best options for the freezer. While they are food-safe, they are often made of a much thinner, more flexible plastic that may crack in the freezer.
A surprising storage technique for food—you can actually wrap sandwiches in plastic wrap and store them in the freezer! You can make sandwiches ahead for quick and easy lunches and quick meals. Common fillings that freeze well include nut butters, canned tuna and salmon, and cooked roast beef and chicken.
Flour tortillas are preferred because they hold up best. Note: Corn tortillas will not work well for freezing. Brown rice – Try our Instant Pot Brown Rice recipe. Substitute ideas: white rice or quinoa.
