How to Choose Takeout Containers: Microwavable #5 PP, Paper Meal Boxes, Soup Bowls, Heat Resistance and Plastic Codes

Quick Answer

For microwaving, choose #5 PP containers, heat resistant to about 100–140°C and the most microwave-friendly common plastic; #6 PS resists only about 70–90°C and should not be microwaved. Paper meal boxes usually have a plastic lining and are generally not recommended for microwaving. Use lidded soup bowls for hot soup, and tamper-evident containers for delivery so customers know the food was not opened.
