Is it okay to microwave food in cardboard?
Is It Safe to Microwave Cardboard? If you're using microwave-safe cardboard (meaning cardboard that is pure cellulose), then you can microwave it for short periods of time. Just keep it between 60 and 120 seconds, and check every 30 seconds to reduce the risk of overheating the cardboard.
These can range from biodegradable materials such as Bagasse or wood, paper and card, to recycled materials such as polypropylene and PET.
It's safe to heat up foods in glass, ceramic, and containers with a waxy finish. This includes Chinese takeout containers—but remember to remove the metal handles prior to microwaving. You're also good to use paper goods (such as paper plates and paper towels) as well as parchment paper.
Cardboard boxes that have contained raw food may absorb moisture, allowing bacteria to grow, and possibly contaminate other food. Cardboard cannot be cleaned and sanitized. Waxed corrugated fiberboard, used to ship produce, is able to resist moisture, but not completely, which potentially allows microorganisms to grow.
No, do not ever put a pizza box in the oven. If the cardboard reaches a temperature of 427 degrees fahrenheit the cardboard will ignite. Even if you don't turn your oven up to the temperature there is still a chance that the cardboard will catch fire, especially if you have an older model oven.
Unfortunately, single-use plastic containers are typically not microwave-safe. This tends to be the majority of restaurant to-go containers, so check for a microwave-safe label before putting that container in the microwave. You can also repackage your leftovers in microwave-safe containers.
Unfortunately, cardboard can contain glues, waxes and other materials that can make it a safety hazard in the microwave. Some cardboard takeout boxes even have metal handles or fasteners that can cause sparks and present a fire hazard.

Cardboard can ignite at temperatures as low as 451 degrees Fahrenheit. So if you put cardboard in the air fryer, it will likely catch on fire. In addition to being a fire hazard, cardboard can also release harmful chemicals when heated.
Composition of cardboard
The cardboard we use for our food packaging, referred to as solid board, consists of a grey inner layer that has been made from recycled paper and cardboard.
Paper and cardboard – Relatively inexpensive and often recyclable, paper and cardboard packaging is ideal for sandwiches, baked goods, and, of course, pizza. You can opt for recycled paper packaging to reduce your carbon footprint and offer an eco-friendly alternative to your customers.
What will takeaways use instead of plastic?
Metal is the strongest alternative to single use plastic. The initial cost of metal products is high, but they can be recycled and reused. Enterprising takeaways and restaurants have implemented their own reuse schemes for metal containers (BBC). The customer can return the tin container for cleaning and reuse.
Cardboard pizza boxes can go in the microwave as long as they are not made with any paper coating or plastic glue that can become flammable when heated. To ensure your pizza reheats safely and without any harmful chemicals, use a microwave-safe plate and place the pizza box on top of it.
Typical paper bags, such as those used in grocery stores, do not have susceptors and can release toxins and fumes when warmed up. Because microwaves produce heat so quickly, the bag could catch fire. It's safe to say you'll want to keep all grocery store bags out of the microwave.
The fact that Chipotle bowls are biodegradable does not mean they should be put in the microwave. Since their lining includes PFAs, chemicals that are not only bad for the environment but can also contaminate your food, you should NOT be microwaving Chipotle bowls.
Check for Labels Indicating Your Paper Bowls Are Microwave Safe. The bottom of many microwave-safe containers states that they can be microwaved. You usually look for a label stamped into the container that gives you the green light on glassware, ceramic kitchenware, and plastic bowls.
