Can Disposable Food Containers Go in the Microwave?

The Basics: Can You Microwave Take-Out Containers?

• Plastic Food Containers with Lids: Most plastic food containers with lids are microwave-safe, but it depends on the material. Containers made from materials like polypropylene (PP) and polyethylene terephthalate (PET) are generally safe to microwave. However, always check for a microwave-safe label or symbol on the bottom of the container.
• Chinese Food Containers: The classic Chinese food containers (you know, the foldable white boxes with the wire handle) are usually made from paperboard or sometimes plastic. These containers are often not designed to go in the microwave, especially if they have a wire handle, which can spark. If the container is purely paper-based, it’s better to transfer your food into a microwave-safe dish before heating.

How to Heat Food in Plastic Containers

• Check the Label: Always look for the “microwave-safe” label. If the container isn’t labeled, it’s safer to transfer the food to a microwave-safe dish, like a glass or ceramic bowl.
• Remove the Lid: It’s important to remove the lid before microwaving your food. Most plastic lids are not designed for microwave use and could warp or melt. If you must cover your food, use a microwave-safe plate or microwave-safe cover.
• Avoid High Heat: Microwaves work by creating heat quickly. To prevent the container from warping, avoid using high heat settings when microwaving plastic. Start with medium power, and stir the food every minute or so for even heating.
• Be Careful with Hot Food: When removing the container, be cautious—plastic can get very hot, and it’s easy to burn yourself. Use oven mitts or a thick towel to handle the container safely.

How to Heat Food in Chinese Food Containers

• Paperboard Containers: Most traditional Chinese food containers are made from paperboard, which is not microwave-safe. When exposed to high heat, the paper can scorch or catch fire. If your container is purely paper, it’s best to transfer the food to a microwave-safe bowl before heating.
• Plastic Chinese Food Containers: Some Chinese food containers may be made from plastic, and these are usually microwave-safe. If you see a microwave-safe symbol on the bottom, then it should be okay to heat in the microwave. Again, remove the lid before microwaving.
• Avoid the Metal Handle: If you’re dealing with a classic Chinese food container that has a metal handle, never microwave it. Metal can cause sparks in the microwave, which could lead to a fire.
• Transfer to Microwave-Safe Containers: If in doubt, always transfer your food to a microwave-safe container. It’s an extra step, but it ensures your food is heated safely without risking damage to the container or a potential fire.

Tips for Reheating Food Safely

• Don’t Overcrowd: When microwaving, try not to overcrowd the container. If you have a lot of food, microwave it in smaller portions to ensure even heating.
• Stir Frequently: Microwaves often heat food unevenly. Stirring your food halfway through reheating helps distribute the heat and avoids cold spots.
• Cover Your Food: If you’re not using a lid, use a microwave-safe paper towel or plate to cover your food. This helps keep moisture in, preventing your food from drying out.
• Use the Right Power Level: Microwaves work by creating heat quickly, and high heat can make your food rubbery or unevenly heated. If you’re reheating something delicate, use a lower heat setting for longer to get the best results.
