Takeout food is a lifesaver for busy individuals and families, delivering delicious meals straight to your door. However, many find themselves wondering about the practicality and safety of reheating leftovers in that plastic takeout container. Is it safe to microwave plastic takeout containers? In this article, we’ll delve into the science behind microwaving plastics, the potential risks, and the best practices for safe reheating.
The Rise of Plastic Takeout Containers
Over the past few decades, the rise of fast food, the delivery industry, and meal prep services has led to an increase in the use of plastic takeout containers. These containers are often lightweight, affordable, and convenient, making them ideal for restaurants and consumers alike. However, concerns regarding their safety when exposed to heat have emerged.
What Are Plastic Takeout Containers Made From?
Most plastic takeout containers are made from one of several types of plastic, primarily:
- Polypropylene (PP): Recognized by the recycling code #5, this plastic is often used for containers that need to withstand higher temperatures. It has a higher melting point, making it generally safer for microwaving.
- Polystyrene (PS): This plastic is commonly found in disposable foam containers. It is less heat-resistant and can warp or melt when exposed to high temperatures.
Understanding the materials helps determine whether a specific container is microwave-safe.
Microwave-Safe Labels
Many manufacturers label their plastics with specific symbols indicating their suitability for microwave use. Look for the following indicators when assessing whether your takeout container is safe:
- Microwave-Safe Symbol: This symbol usually resembles a microwave with radiating waves.
- Recycling Code: Plastics with recycling codes #1 (PETE), #2 (HDPE), and #5 (PP) are generally safe for microwave use, while codes #3 (PVC) and #6 (PS) are not advisable.
Potential Risks of Microwaving Plastic Takeout Containers
While many plastic takeout containers are designed to endure some heat, potential risks associated with their use in the microwave include:
Chemical Leaching
One of the primary concerns with heating plastic is the potential for chemical leaching. Certain chemicals found in plastics—such as BPA (bisphenol A) and phthalates—can migrate into food when the plastic is heated. These substances are linked to various health issues, including hormonal disruptions and increased cancer risk.
Research and Regulatory Bodies
Organizations like the FDA have studied the safety of plastics extensively. They have deemed some plastics, such as PP, safe for microwave use, while others raise concerns. However, ongoing research continues to explore the long-term effects of these chemicals on health.
Deformation of Containers
Heating plastic containers can cause them to warp, melt, or lose their shape. This deformation not only makes the container unusable but can also lead to spills or leaks, causing a mess in your microwave.
Hot Spots in Food
The microwave heats food unevenly, which can create hot spots while other parts remain cold. This uneven heating is particularly problematic when reheating food in plastic containers, as it can increase the risk of the container warping or leaching chemicals into the food moreover, it can pose a burn risk when consuming food that may be extremely hot in some areas yet cold in others.
Best Practices for Safe Microwaving
If you’re determined to microwave your plastic takeout containers, there are best practices to follow that can minimize risks:

Before reheating, take a closer look at the container. Check for microwave-safe indicators and the type of plastic. When in doubt, consider transferring your food to a microwave-safe glass or ceramic dish.
Avoid High Temperatures
Microwave on low to medium heat settings to reduce the risk of deformations and chemical leaching. If you notice any signs of melting or warping, stop immediately and transfer your food to a different container.
Reduce Cook Time
To prevent overheating, reheat your food in shorter intervals, stirring or rotating periodically. This approach encourages even heating and minimizes hot spots, reducing the chances of a steaming, overcooked mess.
Alternatives to Plastic Takeout Containers
For those looking to play it safe but still enjoy takeout food, consider switching to these alternatives:
Glass Containers
Glass containers are typically microwave-safe and do not leach harmful chemicals. They are also more durable and can last longer than plastic.
Silicone Containers
Food-grade silicone containers are flexible and heat-resistant. They can withstand high temperatures without the risk of melting or chemical leaching.
Reusable Meal Prep Containers
Investing in high-quality, microwave-safe containers made of glass or BPA-free plastic can ensure safety and reduce reliance on single-use takeout containers.
General Safety Tips for Reheating Food
Besides container safety, observing general food safety measures when reheating is crucial. Here are some key points to remember:
Check Food Temperature
Ensure reheated food reaches an internal temperature of 165°F (74°C) to kill potentially harmful bacteria. Using a food thermometer can make this easier.
Cover Your Food
Cover your food with a microwave-safe lid or microwave-safe wrap to trap steam and promote even cooking. This practice also helps prevent splatters.
Conclusion
In conclusion, whether it’s safe to microwave plastic takeout containers largely depends on the material and specific guidelines set by manufacturers. Always prioritize your health and safety by checking for microwave-safe labels and inspecting the type of plastic. If in doubt, consider transferring your food to a safer alternative.
By following best practices for reheating food and making informed choices, you can enjoy your takeout meals without compromising your health. Remember that elevating your food safety game often translates to longer-lasting health benefits, making it worth the effort.

What types of plastic are microwave-safe?
The types of plastic that are generally considered microwave-safe include those that are labeled with a microwave-safe symbol, typically a container with wavy lines. Common microwave-safe plastics are made from polypropylene (PP) and polyethylene (PE). Always check the bottom of your containers; if they lack a clear indication of being microwave-safe, it’s better to err on the side of caution.
Microwave-safe plastics are designed to withstand heat without melting or leaching harmful chemicals into food. However, just because a plastic container is labeled as microwave-safe doesn’t mean it’s appropriate for all types of food. Foods with high fat or sugar content can cause containers to overheat more quickly, potentially compromising their structural integrity.
Can all takeout containers be microwaved?
Not all takeout containers are suitable for microwave use. Some containers, especially those made from styrofoam or certain types of plastic, can warp or melt when exposed to high temperatures. Styrofoam, in particular, can release harmful chemicals when heated, making it unsafe to use in the microwave.
If your takeout container doesn’t have clear labeling indicating it’s microwave-safe, it’s wise to transfer the food to a known safe dish before reheating. Glass or ceramic containers are excellent alternatives since they are microwave-friendly and won’t leach toxins into your food.
How can I tell if a plastic container is microwave-safe?
To determine if a plastic container is microwave-safe, first look for the microwave-safe symbol, which typically consists of wavy lines or a container icon. Additionally, containers often have recycling symbols that indicate what material they are made from; look for those made from PP or PE as they are generally safer for microwaving.
If there are no identifying marks, consult the manufacturer’s guidelines if available. When in doubt, it’s best to transfer your food to a more confirmed microwave-safe dish, such as glass or ceramic, to avoid any health risks.
