Ziploc® Containers with lids feature easy-to-use, leakproof Smart Snap technology. They are BPA free and safe for use in the microwave, dishwasher, freezer and fridge (when used as directed). Use them to store food, organize supplies, or while on the go.
Both Zip Lock bags and plastic containers are effective for freezing food, but each has its advantages. Zip Lock bags are more space-efficient and allow for easy removal of excess air, which helps prevent freezer burn. They are ideal for flat, stackable storage.
Only freeze food in plastic containers designed for the freezer. 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.
- 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.
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.

Zip-top bags are great for freezing food because it's easier to get all the air out of them than it is with rigid containers. And zip-top bags have an added space-saving benefit: You can stack them, if you lay them flat to freeze first.
Airtight Seal
Air that sneaks into a container or bag after it's been closed can lead to freezer burn, ice crystals, and dry, leathery food. A container with an airtight seal limits those issues and keeps your frozen food at peak quality.
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 and crack and the wiper seal could be deflected.
Those materials can split, crack and sometimes even shatter when subjected to freezing. However, freeze grade plastics are specially designed to retain some flexibility while still retaining structural rigidity in freezing environments. Freeze Grade Plastic is moisture vapor resistant and has low odor absorption.
Whichever chemicals they contain, plastics break down over time and can potentially release trace amounts into food. “This is more likely to happen when the plastic has been heated or when it's old and has been repeatedly used and washed,” she says.
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.
Glass containers with tight-fitting lids are an excellent choice as they do not absorb odors. Another way you can freeze chili and store it is in heavy-duty plastic containers, provided they are specifically designed for freezer use.
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 ...
It is part of the Polyethylene (PE) family, which is the most widely used plastic. Polyethylene-Low Density, also known as LDPE, is commonly used in rigid plastic containers. We use a mix of different polyethylene densities to get the ideal strength and flexibility for different bag types.
Rigid containers and flexible bags or wrapping are two general types of packaging materials that are safe for freezing. 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 remove.
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.
Never, ever, ever freeze in glass jars unless you know they're explicitly freezer-safe. Glass that hasn't been tempered risks shattering—particularly if you're freezing a liquid that could expand as it freezes. So skip the canning jars and go for tupperware or freezer bags instead.
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.
Our borosilicate glass products can be put into freezer and can resist till -40°c.
It is safe to freeze meat or poultry directly in its original packaging, however this type of wrap is permeable to air and quality may diminish over time. For prolonged storage, overwrap these packages as you would any food for long-term storage.
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.
A: Yes you can freeze rubbermaid with vented lids.
Freezer burn happens when frozen foods are exposed to cold, dry air, which causes them to dehydrate as the outer layers lose moisture. One of the most commonly recognized signs of freezer burn is the formation of ice crystals on the outside of food, making it appear frost bitten.
