When it comes to microwaving food in plastic containers, it's crucial to identify whether the plastic is safe for microwave use. Most plastics are compounds created from fossil fuels, and not all plastics are created equal. Some plastic formulations are highly suitable for heating food in the microwave, while others may pose risks and should be avoided. The safest way to determine if a plastic container is microwave-safe is to look for a microwave symbol or image on the container's bottom. If there is no such marking, one can refer to the plastic identification number, typically found on the bottom of the container. Plastic marked with the number 5 is generally considered microwave-safe. This plastic, known as polypropylene or PP, has a high heat tolerance and does not easily melt or leach chemicals under microwave conditions. Examples of plastic number 5 containers include yogurt containers, microwaveable meal trays, and reusable containers.

What You'll Learn
Plastic marked with 5 is made from polypropylene (PP)
Plastic containers are a convenient, durable, and effective solution for storing leftovers in the refrigerator or holding prepackaged frozen meals. However, not all plastics are created equal when it comes to heating food in the microwave. Some plastic formulations are perfectly suited for microwave use, while others may pose risks and should be avoided.
Plastic marked with a 5 is made from polypropylene (PP). Polypropylene is one of the most widely used plastics globally and is found in many common household items. It is lightweight, strong, and offers good protection from moisture and chemicals. It is also versatile, allowing it to be twisted and bent without losing its form. This makes it ideal for various applications, such as food containers, bottle caps, and flexible packaging.
Polypropylene (PP) is the only plastic marked with the number 5 and is considered generally safe for microwave use. It has a high heat tolerance and does not easily melt or leach chemicals under typical microwave conditions. Examples of PP products suitable for microwave use include yogurt containers, microwave meal trays, reusable microwave containers, and single-use takeaway containers.
However, it is important to note that while plastic marked with a 5 is generally microwave-safe, it is always recommended to check for specific labels or symbols indicating microwave suitability. Additionally, despite its convenience, there are concerns about the potential health risks associated with microwaving food in plastic containers, including the leaching of chemicals.
To identify plastic marked with 5, look for the number 5 enclosed in a triangle made of arrows, also known as the chasing arrows symbol. This resin identification code is typically found on the bottom of plastic items and indicates that the plastic is made from polypropylene (PP).

Polypropylene has a high heat tolerance
Polypropylene, marked as Plastic #5, is the only plastic that is inherently safe for use in microwave ovens. It has a high heat tolerance and does not easily melt or leach chemicals under microwave conditions. This makes it a popular choice for containers designed to hold food, such as yogurt pots, meal trays, and both reusable and single-use takeaway containers.
Polypropylene is a sturdy and heat-resilient plastic. It can withstand temperatures up to 230°F (110°C), which is higher than the maximum temperature of most microwaves. This makes it a safe choice for consumers, as it is unlikely to deform or release toxic chemicals when used as intended. Its high heat tolerance also means that it can be safely used in other applications, such as food storage containers, without the risk of it deforming or leaching chemicals over time.
The safety of using plastics in microwave ovens has been a topic of concern and research. While polypropylene is generally considered safe, it is important to note that all plastics have specific temperature limits. Even those labelled as microwave-safe or BPA-free should be properly recycled once they reach their temperature threshold. This is because plastics can release chemicals when heated, and these chemicals can be absorbed by food.
To ensure food safety and appliance longevity, it is important to follow evidence-based information and scientifically-validated safety practices. Consumers should look for plastics that are specifically labelled as microwave-safe and BPA-free. They should also be mindful of the type of plastic and its temperature tolerance, especially when heating foods with higher fat content, as this increases the risk of chemical migration.
While polypropylene is a safe option for microwave use, it is not the only option. Glass and ceramic containers are always safe to use in microwaves and do not pose the same risks as plastics. However, for those who prefer the convenience and durability of plastic, polypropylene is a good choice due to its high heat tolerance and widespread availability in food containers.

It is the only plastic considered generally safe for microwaving
When it comes to microwaving plastic, it's important to exercise caution as not all plastics are created equal. Some plastic formulations are perfectly safe for heating food in the microwave, while others may pose risks and should be avoided. To determine if a plastic container is microwave-safe, you can look for a microwave symbol or image, typically on the bottom of the container. If no such symbol exists, you can refer to the plastic identification number, also known as the resin identification code or recycling code.
Plastic #5, also known as polypropylene or PP, is the only plastic that is generally considered safe for microwaving. It is identified by the number 5 printed on the plastic item, usually on the bottom. Polypropylene has a high heat tolerance and does not easily melt or leach chemicals under microwave conditions. It is commonly used for yogurt containers, microwavable meal trays, reusable microwave containers, and single-use takeaway containers.
Other types of plastics, such as Plastic #1 (PETE or PET), Plastic #2 (HDPE), and Plastic #4 (LDPE), may be microwave-safe when reinforced with strengthening chemicals to prevent melting. However, they are not considered high-heat food safe. It's important to differentiate between the subtypes of Plastic #1: APET and CPET. APET, or Amorphous PET, is transparent and used for cold food and drinks. It is not microwave-safe as it may leach chemicals or melt. On the other hand, CPET, or Crystalline PET, is opaque and engineered for higher heat tolerance, making it suitable for microwave and oven use.
While Plastic #5 is generally considered safe for microwaving, it's important to remember that all plastics have specific temperature limits. Even those labeled as microwave-safe should be replaced when they show signs of wear, such as cracks, discoloration, or warping. Additionally, glass and ceramic containers are always a safer alternative to plastic when microwaving food.

It is used for frozen meals and food storage containers
Plastic containers are widely used for storing food, but some plastics contain harmful chemicals such as BPAs, which are unsafe for human consumption and can lead to health problems. The Food and Drug Administration (FDA) in the US has undertaken multiple studies on BPA due to increasing public concern.
Plastics are marked with resin identification codes, which are numbered symbols usually found on the bottom of the container. Plastic number 5, or polypropylene (PP), is the only plastic that is generally recognised as safe for use in microwaves. It has a high heat tolerance and does not easily melt or leach chemicals under microwave conditions. It is often used for frozen meals and food storage containers, as well as yoghurt containers, microwaveable meal trays, and takeaway containers.
Food-grade plastic containers are marked with numbers 1, 2, 4, or 5, indicating that they are safe for food storage. Number 5 plastic containers are also considered safe for storing food without the risk of toxic chemicals infiltrating the contents. However, it is recommended to minimise the use of plastic around food, and to replace plastic containers with glass alternatives where possible.
While plastic containers marked with a number 5 are considered safe for microwave use, it is important to note that not all plastics are created equal. Some plastic formulations are not designed to withstand high temperatures and may release toxic chemicals when heated. Therefore, it is always important to check the labelling on plastic containers to ensure they are certified for microwave use.
