What You'll Learn
Use hot and cold water
Using hot and cold water is an effective way to unstick two plastic containers. This method works based on the principle that cold causes contraction, while heat causes expansion.
First, place the containers in a bathtub or sink, depending on their size. If you are using a sink, fill it with enough hot water to cover half of the outside container. If you are using a bathtub, fill it with enough hot water to submerge the bottom container.
Next, fill the inside container with cold water and ice cubes. You can also use a wet towel that has been in the freezer instead of ice. The cold water and ice will cause the inner container to contract.
After two to three minutes, try pulling or twisting the containers apart. The outer container will have expanded from the hot water, while the inner container will have contracted from the cold water and ice, making the containers easier to separate.
If the containers are round, you can try rolling them back and forth on the counter until they come apart. Alternatively, you can try using cooking oil or dish soap to help the containers slip apart more easily.

Try a flat tool
One of the easiest ways to separate plastic containers is by using a flat, sturdy tool like a butter knife, putty knife, or spatula. Firstly, gently insert the tool between the two containers where they are stuck. Then, wiggle the tool slightly to create a small gap. Slowly work your way around the edges, applying even pressure to avoid cracking the plastic. Once a gap is created, gently pull the containers apart. Avoid using sharp tools like screwdrivers, as they can scratch or damage the containers.
If the containers are stuck due to tight stacking or temperature changes, you can also try applying heat to loosen the plastic. Use a hairdryer on a low or medium setting to warm the edges of the containers where they are stuck. Move the hairdryer evenly around the edges for a few minutes. Once the plastic feels slightly warm, try gently pulling the containers apart. Be cautious not to use high heat or direct flames, as this can warp or melt the plastic.
Additionally, you can try to equalize the pressure by warming the containers and the air inside. As the air molecules heat up, they move faster and bounce against the containers, reducing the negative pressure. However, this method may cause the plastic to expand, making it more difficult to separate the containers.
Another suggestion is to try the "pull really hard" method, especially if the containers have handles. Turn the containers upside down and step on the handle of the inner container. Grab the collar of the outer container, twist, and pull.

Twist and wiggle
Plastic containers can become stuck due to tight stacking, temperature changes, moisture and humidity, and weight and pressure. One way to separate them is to use a twisting motion to break the seal between the containers.
- Hold the bottom container firmly in place. If the containers have handles, you can try turning them upside down and stepping on the handle of the inner container for more leverage.
- With your other hand, grip the top container and twist it back and forth while attempting to pull it up and away from the bottom container.
- Wiggle the top container slightly as you continue to twist and pull. This will help to create a small gap between the containers.
- Once a gap is created, work your way around the edges, applying even pressure to avoid cracking the plastic.
- Continue twisting and wiggling the containers until they come apart.
If the containers are still stuck, you may need to try a different method or combination of methods, such as using a flat tool for gentle leverage, applying heat to loosen the plastic, or using hot and cold water to create simultaneous expansion and contraction.

Use air pressure
Using air pressure is an effective way to separate stuck plastic containers. This method involves breaking the vacuum seal between the containers by introducing air into the gap between them. Here are some detailed steps to help you unstick your containers using air pressure:
First, try to gently pry up the lip of the containers to create a small opening. This can be done with a flat, sturdy tool like a butter knife, putty knife, or even a screwdriver if you're careful. Wiggle the tool to widen the gap slightly. If you don't have any tools, you can try using your fingers to pry the containers apart.
Once you have a small opening, it's time to introduce air pressure. If you have access to an air compressor, you can use it to blast air into the gap. Alternatively, you can try using a pump or even a needle valve meant for inflating sports balls, as suggested by someone who has dealt with stuck buckets in the past. Insert the pump or valve into the gap and pump or blow air in to increase the pressure between the containers.
As the air pressure builds, the vacuum seal will be broken, and the containers should pop apart. If they don't separate immediately, you can try applying slight upward pressure by gently pulling the containers away from each other while continuing to apply air pressure.
Another method that utilizes air pressure involves temperature differentials. By submerging the bottom container in hot water and filling the top container with ice water, you can take advantage of the simultaneous expansion and contraction of the plastic. This temperature difference creates air pressure differentials that can help unstick the containers.
Additionally, you can try leaving the containers in the sun to heat up, and then filling the top container with ice water. This will cause the top container to shrink, making it easier to separate.
Remember, when using these methods, always exercise caution to avoid damaging the containers or injuring yourself. It is also recommended to clean the containers after separating them to remove any dirt or oil that may have accumulated during the process.

Store in a dry area
To prevent plastic containers from sticking together, it is important to store them in a dry area. Moisture buildup can cause containers to stick, so keeping them in a cool, dry place is essential. This will also help prevent the growth of mould or mildew, which can damage the containers over time.
Storing plastic containers in a dry area is especially important if they are being stored for long periods. When containers are stacked inside each other for extended periods, they are more likely to settle and become stuck. The longer they remain in this state, the more difficult they will be to separate without causing damage.
By keeping the containers in a dry area, you can also reduce the chance of mould or mildew growth, which can be challenging to remove and can affect the integrity of the plastic. Additionally, choosing storage bins with built-in handles can be beneficial. Handles provide a better grip and make it easier to separate the containers if they do become stuck.
To further prevent sticking, you can use liners or dividers between the containers. Parchment paper, wax paper, or thin plastic liners can be placed between the bins to reduce friction and moisture transfer. This simple step can make a significant difference in keeping your containers stick-free.
Overall, storing plastic containers in a dry area is crucial to prevent moisture buildup and the potential for containers to stick together. By taking this precaution, you can avoid the frustration of dealing with stuck containers and ensure their longevity.
