When it comes to storing or serving hot soup, one of the most common questions that arise is whether it’s safe to put hot soup in plastic containers. While plastic containers are convenient and widely available, there are concerns about the potential health risks associated with using them for hot foods. In this article, we’ll delve into the world of plastics, explore the different types of plastic containers, and examine the science behind the safety of using plastic containers for hot soup.
Understanding Plastics and Their Types
Plastics are synthetic materials made from a variety of chemical compounds, including polyethylene, polypropylene, and polyvinyl chloride (PVC). These materials are widely used in packaging, including food containers, due to their durability, flexibility, and affordability. However, not all plastics are created equal, and some types are safer for use with hot foods than others.
Types of Plastic Containers
There are several types of plastic containers that are commonly used for storing and serving food. These include:
- Polyethylene Terephthalate (PET): This type of plastic is commonly used for water bottles, soda bottles, and food containers. PET is generally considered safe for use with cold foods, but it’s not recommended for hot foods.
- High-Density Polyethylene (HDPE): HDPE is a type of plastic that’s commonly used for milk jugs, detergent bottles, and food containers. It’s generally considered safe for use with hot foods, but it’s not as durable as other types of plastic.
- Polypropylene (PP): PP is a type of plastic that’s commonly used for food containers, including microwave-safe containers. It’s generally considered safe for use with hot foods and is more durable than HDPE.
- Polycarbonate (PC): PC is a type of plastic that’s commonly used for water bottles, food containers, and baby bottles. However, it’s not recommended for use with hot foods due to concerns about Bisphenol A (BPA) leaching.
The Science Behind Plastic Containers and Hot Soup
When it comes to using plastic containers for hot soup, the main concern is the potential for chemicals to leach into the food. This can happen when the plastic container is exposed to heat, which can cause the chemicals to break down and migrate into the food.
Chemical Leaching and Hot Soup
Chemical leaching is a process where chemicals from the plastic container migrate into the food. This can happen when the plastic container is exposed to heat, which can cause the chemicals to break down and leach into the food. The risk of chemical leaching is higher when using plastic containers for hot foods, as the heat can cause the chemicals to break down more quickly.
Factors That Affect Chemical Leaching
There are several factors that can affect the risk of chemical leaching when using plastic containers for hot soup. These include:
- Temperature: The higher the temperature, the greater the risk of chemical leaching.
- Type of plastic: Different types of plastic containers have different levels of chemical leaching risk. For example, PET and PC containers are more likely to leach chemicals than HDPE and PP containers.
- Duration of exposure: The longer the plastic container is exposed to heat, the greater the risk of chemical leaching.
- pH level of the food: Foods with high acidity, such as tomato-based soups, can increase the risk of chemical leaching.
Safe Alternatives to Plastic Containers
If you’re concerned about the safety of using plastic containers for hot soup, there are several alternatives you can consider. These include:
- Glass containers: Glass containers are a safe and non-toxic alternative to plastic containers. They’re also more durable and can be used for both hot and cold foods.
- Stainless steel containers: Stainless steel containers are another safe alternative to plastic containers. They’re durable, non-toxic, and can be used for both hot and cold foods.
- Ceramic containers: Ceramic containers are a safe and non-toxic alternative to plastic containers. They’re also more durable and can be used for both hot and cold foods.
Conclusion
While plastic containers can be convenient for storing and serving hot soup, it’s essential to consider the potential health risks associated with using them. By understanding the different types of plastic containers, the science behind chemical leaching, and the factors that affect the risk of chemical leaching, you can make informed decisions about the safety of using plastic containers for hot soup. If you’re concerned about the safety of using plastic containers, consider switching to safe alternatives like glass, stainless steel, or ceramic containers.

Is it safe to put hot soup in plastic containers?
It is generally not recommended to put hot soup in plastic containers, as the heat can cause the plastic to warp, melt, or leach chemicals into the soup. This is especially true for certain types of plastic, such as polyvinyl chloride (PVC) and polycarbonate (PC), which contain chemicals like bisphenol A (BPA) and phthalates that can be released when heated.
However, some plastic containers are specifically designed to be heat-resistant and safe for hot foods. These containers are typically made from high-density polyethylene (HDPE) or polypropylene (PP), which are less likely to leach chemicals or melt when exposed to heat. If you do choose to put hot soup in a plastic container, make sure it is specifically labeled as “heat-safe” or “microwave-safe.”
What types of plastic are safe for hot soup?
As mentioned earlier, HDPE and PP are generally considered safe for hot foods. These types of plastic are less likely to leach chemicals or melt when exposed to heat. However, it’s still important to check the manufacturer’s instructions and labels to ensure that the specific container you are using is safe for hot soup.
It’s also worth noting that even if a plastic container is labeled as “heat-safe,” it’s still possible for chemicals to leach into the soup if it is heated to an extremely high temperature or if the container is damaged or scratched. To minimize this risk, it’s best to use a container that is specifically designed for hot foods and to follow the manufacturer’s instructions for use.
Can I put hot soup in a plastic bag?
It is not recommended to put hot soup in a plastic bag, as the heat can cause the plastic to melt or leach chemicals into the soup. Plastic bags are typically made from a type of plastic called low-density polyethylene (LDPE), which is not designed to withstand high temperatures.
In addition to the risk of chemical leaching, putting hot soup in a plastic bag can also cause the bag to melt or become misshapen, which can lead to a mess and potentially create a safety hazard. Instead, it’s best to use a heat-safe container or a thermally insulated bag specifically designed for hot foods.
How can I tell if a plastic container is safe for hot soup?
To determine if a plastic container is safe for hot soup, check the manufacturer’s instructions and labels. Look for phrases like “heat-safe,” “microwave-safe,” or “dishwasher-safe,” which indicate that the container is designed to withstand high temperatures.
You can also check the type of plastic used to make the container by looking for the resin identification code (RIC) on the bottom of the container. HDPE and PP containers are generally considered safe for hot foods, while PVC and PC containers are best avoided.
What are the risks of putting hot soup in a plastic container?
The risks of putting hot soup in a plastic container include the potential for chemical leaching, melting, or warping of the plastic. Chemicals like BPA and phthalates can leach into the soup and potentially cause health problems, while melting or warping of the plastic can create a mess and potentially lead to a safety hazard.
In addition to these risks, putting hot soup in a plastic container can also affect the flavor and nutritional content of the soup. Chemicals from the plastic can leach into the soup and alter its flavor, while the heat can cause the nutrients in the soup to break down.
