Plastic containers are a great way to store food, but they can be frustratingly difficult to open. Many people have resorted to using knives or scissors to pry them open, while others have tried heating the container or freezing it before pouring hot water on the lid. However, these methods can be dangerous and may not always work. To avoid the risk of injury, it's important to inspect the packaging carefully for any hidden seals or snaps that need to be released before opening. Additionally, some plastic containers may have instructions on how to open them. If you're struggling to open a vacuum-sealed container, one effective method is to boil water in a pot, let it cool slightly, then dip the inverted container into the water so that just the lid is submerged. This will release the pressure and make it easier to open. It's also important to note that plastic containers can become stained from certain foods, but they can be cleaned using a mixture of white distilled vinegar and baking soda.

What You'll Learn
Use hot water to break the vacuum seal
To lift food out of a plastic container, one method is to use hot water to break the vacuum seal. This method is particularly useful if the container has been heated with the lid on, causing the contents to expand and creating a vacuum seal as it cools.
Firstly, find a pot with a diameter larger than the plastic container's lid. Fill this pot with water and place it on the stove to boil. Once the water has boiled, allow it to cool slightly until it is no longer steaming. It is important to wait for the water to stop steaming to avoid burns from the hot steam. You can also wear an oven mitt for extra protection.
Next, invert the plastic container and dip it into the hot water, ensuring only the lid is submerged. You will need to hold the container in this position for about two minutes. The hot water will cause the contents of the container to expand and release the pressure, breaking the vacuum seal.
After soaking the lid in the hot water, place the heated container on a dish towel. The towel will catch any splatters if the contents of the container are released suddenly. Using your fingers or the dish towel, you can then try to pry the lid off. If the lid does not come off easily, repeat the process of heating the lid in the hot water.
This method is an effective way to break the vacuum seal and access the food in the container without having to damage the lid or use excessive force.

Pry the lid with a spoon
If you are struggling to open a plastic container, one method is to use a spoon to pry the lid open. This method is particularly useful if you need to open a metal lid, but it can also be used for plastic lids.
Firstly, hold the container by the bottom, so you are not squeezing and deforming it. Then, take a spoon and place the border of the spoon on the border of the lid. Gently apply some force to slightly pry the lid open. You should hear a 'pop' sound, and then you can try to open the lid normally.
If you are concerned about damaging the lid, you can try to ease the pressure by forcing air inside with the spoon. This method may not work as well for plastic lids, as plastic tends to flex and bind.
Another method is to use a key or a butter knife instead of a spoon. Insert the tip of the key, knife, or spoon under the edge of the lid and lift with a little force to pry it open.
Always be cautious when using sharp tools, and consider wearing gloves and eye protection to protect yourself.

Soak in vinegar and scrub with baking soda
Vinegar and baking soda can be used to clean plastic. To make a vinegar solution, mix equal parts vinegar and water in a container. Apply the mixture to the plastic and scrub to remove any grime. Rinse the plastic with water and dry it with a clean towel.
To make a baking soda mixture, combine 3 tablespoons of baking soda with 1 tablespoon of water. You can adjust this mixture to achieve a toothpaste-like consistency by adding more baking soda or water. Rub the paste onto the plastic, scrubbing away any sticky grime. Rinse the plastic with water and dry it with a clean towel.
You can also combine vinegar and baking soda with liquid soap to create a cleaning solution. To make this mixture, add 1 2/3 cups of baking soda, 1/2 cup of liquid soap, 2 tablespoons of vinegar, and 1/2 cup of water. Mix the ingredients well and apply them to the plastic. Scrub the surface to remove any grime, then rinse and dry the plastic.

Freeze the container
If your food is stuck to the inside of your freezer, you can use the following methods to safely remove it without damaging the freezer or the container. Firstly, do not attempt to pull or push the food as this will not work and may damage the freezer. You should also avoid using a hairdryer as this could cause an electrical shock.
Instead, you can use the freezing method. Place a small bowl of steaming hot water in the freezer and leave the door closed. The hot water will speed up the melting process and reduce the thick layers of ice that may be causing the food to stick. You can also sprinkle salt onto the floor of the freezer and pour hot water over it to melt the ice. Once you can find some purchase underneath the item, use a plastic putty knife to carefully lift it out.
If you are freezing food in containers, there are several options to choose from that are safe and environmentally friendly. Glass jars and containers are a good alternative to plastic as they are microwavable, dishwasher-safe, and often freezable. However, be mindful that you should not freeze liquids in glass containers as they can expand when frozen and cause the glass to break. Always defrost food properly before reheating to avoid sudden temperature changes that can cause glass to shatter.
Stainless steel containers are another option that is versatile, easy to clean, and effective at keeping food fresh while locking in nutrients. However, they should never be used in the microwave.
Reusable silicone bags are a good alternative to plastic bags as they are sturdy, seal tightly, and store flat. They also allow less transmission of air and moisture, which can cause freezer burn, and last longer than plastic.
If you are using plastic containers, always allow food to cool before freezing it. This will prevent the container from cracking due to sudden temperature changes.

Look for hidden clues like snaps and seals
When it comes to plastic containers, there are various sealing mechanisms to keep food fresh and prevent leaks. Understanding the different types of seals and closures is essential for effective food storage and preservation. Here are some hidden clues to look for when dealing with plastic containers:
Snaps and Buttons
Plastic snaps or snap buttons are commonly used in plastic containers, providing a secure and convenient closure. These snaps typically consist of two identical caps (front and back), a stud, and a socket. When fastened, you should hear a clicking sound, indicating a proper seal. To open, simply apply pressure to the centre of the snap and pull the lid away from the container.
Seals and Lids
Vacuum seals are created when the container and lid are heated together and then cooled. This process removes air from the container, creating a tight seal. To identify a vacuum seal, look for a dented lid or a slight indentation around the edges. To open, you can reheat the container, causing the contents to expand and release the pressure, or use a spoon to gently force air inside and pry it open.
Leaks and Repairs
If your plastic container has a leak, it is important to identify the source and type of leak. Look for visible cracks, holes, or damaged seals. Clean the area around the leak with soap and water, and use sandpaper to create a rough surface for better adhesion. You can then use adhesive tape, silicone sealant, or hot glue to repair the leak and create a strong bond.
Recycling Symbols
Most plastic containers have a recycling symbol on the bottom, which can help you identify the type of plastic. For example, PE is typically marked with a "1" or "2" inside the recycling symbol, while PP is indicated by a "5." Understanding the type of plastic can help you choose the appropriate repair methods and ensure effective sealing.
By paying attention to these hidden clues, you can better understand the sealing mechanisms of plastic containers and take the necessary steps to open, repair, or preserve your food items effectively.
