Reheating pizza without box:

If your pizza gets cold due to any reason, you should reheat it without a box. Make sure to reheat your pizza without a box because it will save your pizza surface from getting any type of harmful chemicals. Reheat your pizza without the box is healthy and safe for your health. Always keep in mind to reheat pizza without a box, but you need to know some alternatives which are safe.

Harmful chemicals and Flammable material:

Most cardboard is made with plain cardboard, a flammable material. They are also doused with chemicals. If the oven gets heated at a high temperature, the chemicals will be transferred from the box to the pizza surface. 

The cardboard has an auto-ignition point of about 450 degrees F. This level of flammability means that the material can quickly start a kitchen fire if placed into an oven at such a high temperature. If you keep the low temperature, there’s still a possibility that the box can catch on fire; that’s why I’d urge you to avoid doing so at all costs. 

Most types of food packing, including pizza boxes, contain chemicals, especially PFAS (Per-and poly-fluoroalkyl substances). They help make a material grease, stain, and water resistant; however, they don’t break down naturally and have been linked to cancer and other similar life-threatening diseases in humans. 

Additionally, most pizza shops added their store information and other designs directly onto the pizza boxes to make it easy that where this product came from. The printing ink used in their designs should not go in the oven or be heated at high temperatures. Moreover, the inked design stickers are also flammable and are printed on the boxes.

Why is a pizza box used?

The idea behind the pizza box is to protect the integrity of the pizza inside it. Because it is near perfect fit, it minimizes any movement.

It not only stops pizza from slipping over and spoiling the topping, but it also prevents it from sliding around too much, which would cause it to lose some heat as much as the box is stored flat and the right way up. 

The box is also designed to make it easy to slide its precious content out onto a warming stone or be used as a makeshift cutting board.
