PIZZA

You all know what is pizza. In here I'm not going to describe you about pizza but pizza packaging .Here we discuss about pizza packaging and how they made.

This article describes the often-ignored but high-potential world of pizza packaging. Virtually everyone has “experienced” hundreds of pizza boxes in their lifetime. Yet few know anything about the vessel that carries their favorite food. Pizza Boxes is what this Power Packaging section is about. After you've gained an overview of the origins of the good ol' pizza box, check out additional pizza packaging articles in the Power Packaging menu to the left.Although a pizza box can be made of most any material — ex., plastic and molded paper pulp — paper has generally been the material of choice for most pizza box concepts, for three reasons. First, it's economical. Second, it has substantial stacking strength, or crush-resistance. Third, it resists condensation build-up on the interior surfaces.

                                                                        Paper-based pizza packaging comes in two forms: (1) paperboard and (2) corrugated board, often incorrectly referred to as “cardboard.” Paperboard — also known as boxboard, cartonboard, and cardboard — is basically a single sheet of very thick paper. Examples include chipboard and SBS (solid bleached sulfate) board.

                           

      The most common form of corrugated board used for pizza boxes is single wall corrugated. It consists of two outer sheets of flat paper, called facings or liners, glued to a fluted, or corrugated, inner sheet, called medium. Corrugated board was invented in the 19th century and first used for making boxes as early as 1894. In basic concept it has remained unchanged for over a hundred years and, so, carries the distinction of being one of the most durable and versatile of modern inventions.

                                           

                              Pizza packaging probably began in the 1940s after World War II. With the advent of carry-out pizza, the first pizza package was most likely a combination of paper bag and a chipboard or corrugated square. With this, the pizza is placed on the square and the entire unit is slid into the bag which is taped or stapled shut. Subsequently, a circle replaced the square shape, making it easier to insert into the bag. This package was convenient (no pre-folding needed) and highly economical. But it lacked stacking strength, heat retention, and product protection capability — three requirements for good pizza packaging.

Soon the paperboard pizza box appeared. It resembled the structure of bakery cake cartons of the time, in that the four corners of the box were formed by inserting a tab projecting from one wall into a slot in an adjacent wall. Due to the thinness of the material, it requires a piece of aluminum foil or a chipboard or corrugated pad in the bottom. To impart rigidity and prevent accidental cover opening, the box is stapled or taped shut on all sides. This was slightly less convenient than the circle and bag package, but it imparted a measure of heat retention and product protection — two key factors to functional pizza packaging.

Circa 1960 the corrugated pizza box was introduced. Several individuals and companies claim to be the originator. The switch to corrugated board provided substantial stacking strength, improved heat retention, and greater product protection over the paperboard pizza box. Tom Monaghan, founder of Domino's Pizza, has stated that adopting the corrugated pizza box was one of the fundamental innovations responsible for the growth of the Domino's Pizza delivery system.

Two basic design variations of the corrugated pizza box have evolved. The first is a non-connected-corner carton in which the front wall and two side walls each have a flap appended to the top edge which is positioned parallel to the bottom panel. This structure formed the basis of the original Domino's Pizza box (used until 1988) and also of a carton that has become known as the “Chicago folder.” The box blank for the original Domino's Pizza folder box looked like this.
