Yes. You can use regular zip-top storage bags in the freezer. However, foods stored in these bags in the freezer might not hold up as well over long periods of time, and can be more prone to punctures and rips.
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.

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.
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.
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.
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.
Most food-grade containers can be frozen, but some work better than others. Filmy plastics and paper cartons won't keep moisture out for long. Meat sold on Styrofoam trays and wrapped in clingy plastic will deteriorate quickly and should be rewrapped in freezer or butcher paper or vacuum sealed.
Frozen Food and Power Outages: When to Save It and When to Throw It Out. A full freezer will hold a safe temperature for approximately 48 hours (24 hours if it is half full and the door remains closed).
Absolutely! If you've used the bags for food storage, we recommend handwashing. We don't recommend reusing the bag if it was used to store raw meat, fish or any allergy-triggering foods – safety first!
7” x 7 7/16” (17.7cm x 18.8cm)
Safe for use in the dishwasher (top and bottom rack), microwave, oven, fridge, and freezer.
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.
The bottom freezer drawer for frozen fruit and vegetables – peas, sweetcorn, broccoli, oven chips, berry mixes, etc. The middle freezer drawer for frozen meat, fish and dairy products – chicken breasts, chicken nuggets, beef mince, battered fish, salmon fillets, ice cream, frozen milk, cheese, etc.
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.
Available options include non-toxic glass, BPA-free plastic containers or storage bags labeled as freezer-safe. Containers should be able to be labeled with the name and contents of the food items or transparent enough for you to easily view food items stored in the container.
Leaching is when chemicals such as BPA are transferred from the plastic to food. It is commonly transferred through changes in temperature. For example, when you microwave food, if you are using plastic, the chemicals will leach in to your food. Similarly, leaching can also occur if left in the freezer.
High-density polyethylene (HDPE plastic) Low-density polyethylene (LDPE plastic) Polyethylene terephthalate (PET/PETE)
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 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.
Containers made of PET plastics can release chemicals at a temperature of 25°C and at temperatures of 50°C and above, the leaching of chemicals can occur very rapidly. Food high in fat content should never be heated in plastic as the fat better absorbs chemicals.
