Can You Put A Pizza Box In The Oven?

April 29, 2025 Food Packaging

Pizza holds a special place in the hearts of foodies. The savory treat with crispy crust, mozzarella, and delicious topping has become a go-to food solution worldwide. According to the research, American people consume over three billion pizzas in a year which is greater than the total population of America.

When talking about packaging, pizzas typically come in cardboard boxes in rectangle, hexagon, or square shapes. Sometimes, when pizza gets cold during delivery or leftovers in the freezers, people may want to put their box directly in the oven to avoid hassle. Here raises a very important question that must have come to your mind too (no matter if you neglected it): “can you put a pizza box in the oven?” The hint is it may cause several hazards. But if you want a straightforward ‘yes’ or ‘no’ then you have to read the important points explained below.

This blog is all about corresponding to this question along with reasons and possible solutions. So, delve deeper if you have the same concern in mind and are eager to remedy it!

Are Pizza Boxes Oven-Safe Or Not?

Let’s get straight to the fact of whether can you put pizza box in oven or not. The answer is no due to several reasons. First of all, it’s the material of the pizza box (the problem maker). Commonly, pizza boxes are made from simple cardboard or corrugated material, which we can not neglect, are excellent for keeping pizza warm for long and safe delivery. However, they are not designed to withstand high temperatures thus resulting in several risks. Here are some other reasons that make your pizza box unsafe to put in the oven:

Reason 1: Flammability

Cardboard is made from ignitable materials and is highly flammable. When put in the oven, cardboard can cause a fire hazard in your kitchen. Even if it doesn’t immediately catch fire, cardboard pizza boxes can smolder or release unpleasant odors and toxic fumes. Below are some heat levels of the oven mentioned along with the associated risks:

Temperature	Risk Level
425°F	High risk of ignition
350°F	Moderate Risk of smoldering
250°F	Low risk of warping

Reason 2: Chemical Coatings

Brands often get their pizza packaging boxes coated for extra protection and better presentation. However, coatings can play an important role in the secure delivery of pizzas but they are marked as harmful for oven use of pizza boxes. Some coatings contain noxious chemicals that can release fumes even when exposed to minor heat. Below are some chemicals used in pizza box coatings:

Perfluorinated Compounds

PFCs are used to make packaging grease and water-resistant. These compounds are difficult to break down and are persistent in the environment. When exposed to heat, they will be released into the air and result in several health risks such as hormonal imbalance, thyroid disease, and high cholesterol.

Fluorocarbons

These are man-made chemicals that are applied as a coating on pizza boxes. Fluorocarbons are harmful to both human health and the environment. From ozone depletion to chronic respiratory failure and respiratory illnesses, this chemical can cause several risks when exposed to heat.

Per Or Polyfluorinated Alkyl Substances

Per or polyfluorinated alkyl substances are synthetic chemicals that are also known as forever chemicals. When heated, this chemical can cause severe neurological disorders and cancers. Despite their nonstick and water resistance properties, Per or polyfluorinated alkyl substances can become a fire risk.

Reason 3: Inefficiency In Heat Transfer

As we have already discussed, cardboard is not a good conductor of heat so when exposed to heat, it can make your food uneven. When you place a cardboard pizza box in an oven, it can result in a poor eating experience. Because of the uneven heating experience, the crust of your pizza may become soggy while your cheese will become stiffened. It may result in:

Soggy pizza crust
Uneven cheese melting
Lack of crispiness
Loss of flavor and aroma

Reason 4: Risk Of Fire

Imagine you have just put your pizza box in the oven and forgotten about it due to other chores. This can result in devastating fire risks. Cardboard, corrugated boxes, or any other paper-based material through which the box is made can pose a risk of fire even in low temperatures. The risk level and fire hazards of reheating pizza in the box are given below:

Fire Hazard	Risk Level
Cardboard ignition	High risk
Spark generation	Moderate risk
Kitchen fire	High risk
