Introduction: Is Your Packaging Ready for the Freezer?
So, you’re running a food business, and you’ve got plenty of disposable containers for storing meals, sauces, and frozen ingredients.
But how do you know if those containers are actually freezer safe?
After all, nothing’s worse than opening a frozen meal only to find your container cracked or your food freezer-burnt.
This is a real worry, especially if you’ve invested in bulk packaging.
Let’s cut through the noise. Here’s everything you need to know about freezer-safe containers for your business.
What Does Freezer Safe Really Mean for Disposable Containers?

Let’s start with the basics.
Not all disposable containers are built the same.
Freezer-safe containers are designed to withstand the freezing process without cracking, warping, or breaking.
In simple terms, they’re made to hold up in the cold and stay intact, ensuring your food stays fresh.
However, many containers, especially cheaper or low-quality options, might look great but fail when the temperature drops.
So, if your containers aren’t freezer safe, it could lead to big problems:
- Cracking under freezing temperatures
- Leaks ruining your food and your reputation
- Poor insulation, leading to freezer burn
- Customer dissatisfaction – If you’re in foodservice or catering, broken containers mean unhappy customers—and you don’t want that.
If your disposable containers are intended for freezing, they need to meet certain standards.
But how do you tell which ones really qualify? Let’s dig in.
Material Breakdown: Which Disposable Containers Are Best for Freezing?
Plastics
Plastic containers are lightweight, moisture-resistant, and budget-friendly, but they can warp or crack in high heat or cold. Make sure to look for the type of plastic that’s freezer safe. Some plastics such as polyethylene and polypropylene are safe and dependable for freezing. These materials are moisture resistant, light weight and hold up under extreme durability, even in sub-zero temperatures. Their flexibility allows them to be bent and twisted to help prevent cracking, making them ideal for long-term food storage. Polystyrene (PS) doesn’t work either, as it breaks down and becomes brittle, leading to a higher likelihood of breakage.
Below is a comparison:
Plastic Type | Freezing Capability | Durability | Cost |
---|---|---|---|
Polyethylene (PE) | Excellent; remains impact resistant at low temperatures, suitable for freezing applications down to -80°F [-62°C]. | Highly durable, especially in HDPE form; resistant to cracking and moisture. | Generally low-cost, widely available due to common usage in various applications. |
Polypropylene (PP) | Good; can withstand temperatures from -0°F to 240°F [-18°C to 115°C], but may become brittle at extreme cold. | Very durable; high tensile strength and impact resistance, making it suitable for both single-use and long-term products. | Moderate cost; slightly more expensive than PE but offers better performance in many applications. |
Polystyrene (PS) | Poor; becomes brittle at temperatures above 68°F [20°C] and is very brittle at freezing temperatures, making it unsuitable for freezer use. | Less durable compared to PE and PP; more prone to cracking and stress under pressure. | Low-cost; one of the cheapest plastics available, often used for single-use items. |
Paper
While paper-based containers are lightweight, environmentally preferred, and easily recyclable, they are not moisture resistant and may lose structure under frozen conditions. They do great with dry foods.
Paper-based containers are hit or miss. While some are fine for short-term freezing, they’re generally not designed for long-term use. To avoid any leakage, seal them with freezer tape or look for wax linings that offer added protection.
Aluminum
Aluminum is an excellent conductor of extreme cold and is very lightweight. It’s recyclable and leak-resistant, so it’s perfect for casseroles or baked goods.
However, it can definitely warp if you’re not careful about how you use it, so make sure to seal tightly if using foil lids.
Bioplastics
While many bioplastics perform well in freezing conditions(such as corn starch-based bioplastics can withstand freezing temperatures ranging from -5°C to -10°C, PLA can endure temperatures as low as -18°C), some may exhibit reduced mechanical strength or become brittle if exposed to extreme cold for extended periods. Therefore, it’s essential to consider the specific type of bioplastic and its formulation when determining its suitability for freezing applications.
They’re perfect for short-term freezing of made ahead meals.
Bagasse
This is a surprisingly good material for freezing. It’s sturdy and holds up well under low temperatures. For example, InNature Pack’s bagasse containers are tested to withstand -40°C in the freezer for up to 24 hours, and can be stored at -20°C for 30 days without any loss in strength or performance. This makes bagasse an excellent choice for businesses that need reliable, eco-friendly, freezer-safe packaging.
Glass
Glass is strong, chemically inert, and the best material for freeze long-term storage. Tempered and borosilicate glasses are best, as they do not shatter with thermal shock.
While airtight lids are great for keeping out freezer burn, glass containers aren’t flexible. If the food expands in there as it freezes, it can break.
Freezer Safe Disposable Containers for Specific Applications
Not all containers are created equal. You’ll need different options depending on what you’re storing.
Here’s a breakdown:
- Frozen vegetables and meats – Use high-quality plastic or foil for long-term storage and optimal food safety.
- Frozen meals – Sturdy plastic or aluminium containers work best here. They can hold heat and freeze without issue.
- Ice cream – Opt for insulated, leak-proof containers that keep the cold in and prevent condensation.
- Catering services – Consider bagasse (sugarcane pulp) for eco-friendly, freezer-safe options that fit buffets and event needs.
How to Identify Freezer Safe Disposable Containers for Bulk Orders
When buying disposable containers in bulk, always test them first. Here’s how to do it:
- Freeze a test batch – Grab a few of the containers and fill them with food.
- Freeze and thaw – After freezing, let them thaw. Does the container hold up? Does it crack or leak?
- Check flexibility – Is the material stiff or flexible? A good freezer-safe container should have some give.
- Inspect for brittleness – If the container feels brittle after freezing, it’s time to look for a better option.
Signs Your Disposable Containers Are Not Freezer Safe
Got containers you think might be freezer-safe? Here’s how to tell they’re not:
- Brittle material – A container that feels brittle after freezing is a red flag.
- Cracks after freezing – If your containers develop cracks, they’re definitely not freezer-safe.
- Warping – Any signs of warping mean the container can’t withstand freezing temperatures.
- Leaks – If food leaks when thawing, your container wasn’t designed for freezing.
Common Mistakes to Avoid with Freezer Safe Disposable Containers
One of the biggest mistakes people make when freezing food is overfilling containers. You’ll want to make sure to leave some space—about an inch is typically sufficient—for the food to expand while freezing. Containers that are too full will crack or shatter under pressure, particularly if the material is rigid. For example, high moisture soups or stews can make this a challenge, so proper portioning is key.
Another common error is not using a lid or cover that makes an airtight seal. A loose, ill-fitting, or cracked lid invites freezer burn, which will ruin food with discoloration over time. Investing in containers with secure, tight-fitting lids makes all the difference.
Using the wrong materials is another common mistake to avoid. Polystyrene (PS) containers are prone to cracking at low temperatures. On top of that, many BPA-free plastics don’t hold up well against the freezer’s wrath. Research shows that up to 20% of plastic containers marked BPA-free may still leach harmful chemicals when frozen. This is why it’s important to always verify the material type before using them.
This step is frequently forgotten, but it’s key to a helpful freezer. An obvious indication of what is inside and when it was made will help ensure there is no mix-up. Without it, you will lose track and possibly uncooked meals or food may be in there longer than the safe limit.
Container shape and overall design significantly affect performance. Those that are square or rectangular take up less space when stacked. This thoughtful design feature keeps freezer space maximized and organized at all times.
Finally, storing food at the appropriate temperature ensures food is safe and fresh. Keep freezers at 0°F for best quality. Inspecting containers for cracks, brittleness, or other signs of failure after 24-48 hours will help ensure that they’ve withstood the stresses of freezing without damage.
