pizza box or pizza package is a folding box made of cardboard where hot pizza is stored to take home. The "pizza box" also makes home delivery and takeaway much easier. The pizza box should be very resistant, inexpensive, easily stacked, thermally insulated to regulate moisture and suitable for food transport. In addition, it provides space for advertising. The pizza package is different from the frozen pizza, which contains frozen products in hot plastic coated sheets as well as many frozen foods.

Histori
Containers to deliver freshly baked pizzas are at least dated since the 19th century, when the Neapolitan pizza bakers put their products in a multilayered metal container known as stufe (single stufa , "oven") and then send it to street sellers. Aerated containers are round and made of tin or copper. Disposable packaging began to be developed in the United States, after the Second World War. By then pizza became increasingly popular and the first pizza delivery service was created. At first they tried to deliver pizza in a simple cardboard box, similar to the one used in a pastry shop, but this often gets wet, bent or even broken into two. Other pizza chefs try to put pizza on a plate and move it into a paper bag. This partially solves the problem. However, it is almost impossible to transport as well as more pizza in one bag. In this way, the pizza above will damage the other surfaces.
The first patent for a corrugated cardboard pizza box was applied in 1963 and has been featured the current pizza packaging characteristics: blanks, non-adhesive flexibility, stackability and ventilation slots. The combination of these slots along with moisture absorbing materials (absorption agents) prevents the buildup of moisture that marks traditional packing transport. It is assumed that the pizza box is invented by Domino's Pizza, even if they do not apply for a patent. Until 1988 this chain used a type of packaging that the front side did not connect directly to the lateral sides, but flaps mounted on the lateral sides folded inside under the lid. This design is also known as "Chicago folding". Domino's is the first pizza producer to use a large-scale pizza box and in this way extends its shipping range beyond areas close to the pizzeria. Toward the end of the 1960s, delivery services were further developed thanks to the introduction of hot insulation bags.

Requirements
Stability and order
Most packaging for transporting pizza is made of cardboard, because it is cheap and has many useful properties. Both solid fiber boards and single wavy wallboard are used. The corrugated carton used is often of the size of the E flute (microwaves or smooth with a pitch flute of 1.0 to 1.8 mm), but a thick B flute carton with a 2.2 to 3.0 mm flange pitch is also used. Not only does the cardboard geometric construction determine the stability of the box, but also especially the type of paper and its gramatures. For liner most containerboard is used inside the box. This not only keeps the box stable, but also more resistant to moisture and oil. To reduce the space needed to keep the packaging to a minimum, the pizza box is folded just before use from empty. The required storage space depends greatly on the thickness of different materials.
The pizza boxes made of solid fiberboard take about half the boxes of boxes with the size of an E flute cardboard box, and a quarter of space made of cardboard B-flute size. Regardless of the material itself, the stability of the box is determined by the shape it is folded into. This type of pizza box with a firmly attached cover on the side wall that folds into the front wall has established itself as standard. In this case, the box wall is connected at the end and this improves its stability. The traditional way of folding the box is an example of this type of folding. The disadvantage is that the box wall rises vertically which makes cutting the pizza inside the box with a more difficult pizza cutter.
Heat insulation and humidity settings
The pizza box should allow the transport of baked pizzas with minimum losses in possible quality. This means the box has two tasks to accomplish that are not easy to combine: On the one hand, the box should be as close as possible to the cold outside, occasional wind and heat radiation, to keep the pizza warm. To reduce heat flow, the box should be closed as tightly as possible to keep the warm air inside. Consumers consider the temperature between 70 and 85 ° C to be ideal for pizza consumption. On the other hand, the box should keep the pizza from getting wet, so the crust and the lid are crisp on arrival. To be sure of this, condensation caused by pizza must be ejected (showing a hole and some diffusion through the cardboard) or absorbed by the box. Pizza boxes made of single wall corrugated boards not equipped with additional insulation cool down the pizza being transported down too far after just ten minutes.
Oil in pizza dough can extract some essence in cellulose when in contact with untreated corrugated cardboard. To prevent the change of pizza flavor through the ingredients of a pizza box and simultaneously stop the cardboard from getting wet the pizza box has a thin layer of aluminum foil on the inside. Another possibility is to put pizza on aluminum foil, corrugated cardboard mix and blotting paper, or wax paper. However, this changed the thermodynamic properties of pizza boxes significantly. The pizza crust can not release the moisture down, which means the layer beneath it not only blocks the fat from the droplets but also the steam.

Pizza saver
In the US, many pizza boxes include a heat-resistant plastic spacer (typically (polypropylene) placed in the center of a pizza called 'pizza saver' (also known as' package saver ',' tent box ',' pizza table 'or' pizza lid support ') This stops the lid of the box from touching the pizza and prevents the topping (like cheese) sticking to the cover while it is being shipped.The origin of' pizza saver 'goes back to 1985 patent, brought by American Carmela Vitale, a small piece of plastic called spacer often criticized for wasting resources because it is only used once and then discarded.For this reason, ideas for reuse are developed.
Bags and boxes for transportation
There are special transportation bags and boxes for pizza delivery in a pizza box that match the typical pizza box size. Some of these bags can be heated to keep the temperature at the desired level. Mostly, they can be plugged into a socket or powered by a 12-volt car battery. This means that the isolation of the pizza box itself is less important. Pizza boxes with pizza in them should be held horizontally at all times and should be protected from high acceleration to sides and impacts. To ensure this, there is usually a handle on both sides of the carrying case to carry. When combined, this handle allows the box to be carried with one hand by the side of the body. Carry bags are perfect when the lid is connected with the rest of the bag on one side and the remaining three sides can be attached to the lid. A bag can contain about three to five boxes of pizza, which is usually enough for one shipping address. If more pizza should be sent, a higher bag is used or two ordinary bags are placed on top of each other and carried with both hands in front of the body.
Pizza box with thermometer
Pizza boxes by Pizza Hut in Morocco and other countries have an outside thermometer indicator that color the temperature of the pizza inside, letting the outside world know about what is going on inside. When the hot pizza indicator indicates the words 'HOT' in red letters on a white background. However, if the pizza temperature is below a certain value, 'Hot Dot' becomes black and words are no longer readable. If the pizza is delivered to a cold recipient, then the next delivery is free. This indicator is intended for one use only.
Possible contamination
<2.3-Diisopropylnaphthalene_.282.2C6-DIPN.29 "> 2,6-Diisopropylnaphthalene (2,6-DIPN) 2,6-DIPN)DIPN is used as a solvent in certain types of paper. This can be part of the used paper used in the manufacture of packaging such as pizza boxes. Direct contact or evaporation can transfer DIPN from packaging to packaged food, contaminating it. Especially foods that contain fat like pizza with a layer of cheese can absorb DIPN. Until now, there is no knowledge of the dangers to consumer health. However, paper contaminated with DIPN should not be used in the food sector to minimize the danger of contamination.
