19. Pizza Boxes

Key Takeaways Copied to clipboard!

• The modern corrugated pizza box design, known as the Michigan style, was developed in the 1960s by Domino's founder Tom Monaghan to improve stacking, heat retention, and durability for high-volume delivery.  Copied to clipboard!
• Despite innovations like round boxes or designs with built-in utensils, the status quo in pizza box design persists because cost savings (around 30 cents per box for small shops) outweigh marginal improvements to the consumer experience.  Copied to clipboard!
• Contrary to popular belief, cardboard pizza boxes soiled with grease are generally recyclable in most municipalities, though contamination from food residue often leads to them being discarded.  Copied to clipboard!

Pizza Box Collector’s Awakening

• Key Takeaway: Scott Wiener’s obsession with pizza boxes began in 2008 after seeing a distinct yellow and orange box in Israel, contrasting sharply with the standard white boxes of his New Jersey upbringing.
• Summary: Scott Wiener holds the Guinness World Record for the largest pizza box collection, exceeding 1,800 boxes, including one from Antarctica. He saves any box that looks different from the typical flimsy, smudgy red ink designs. The collection highlights the depth of an everyday item often underappreciated by pizza consumers.

Evolution of Pizza Packaging

• Key Takeaway: The shift from copper containers (stufas) and paper bags in Naples to the modern corrugated box in the U.S. followed pizza’s growth as a large, shareable party food post-WWII.
• Summary: Early pizza transport in Naples involved copper containers or horizontal paper bags before the U.S. pizza boom necessitated sturdier packaging. The modern corrugated box, the Michigan style, was developed by Domino’s to stack neatly, retain heat, and offer strength. This design, featuring fluted paper between liners, remains largely unchanged for 60 years.

Corrugated Box Manufacturing Overview

• Key Takeaway: Major packaging conglomerates like Westrock control the entire pizza box supply chain, from forestry and paper production to printing and delivery to restaurants.
• Summary: Westrock produces about 3 billion pizza boxes annually in the U.S., representing 1.7% of their corrugated volume. They offer both custom graphic design services and generic clip-art boxes for branding flexibility. Engineers focus on heat retention, moisture resistance, ventilation, and box height to maximize stacking efficiency in delivery vehicles.

Labor Efficiency in Box Folding

• Key Takeaway: Pizza chains prioritize box designs that minimize labor time during assembly, exemplified by Domino’s patented box that saves three seconds per fold compared to standard corrugated boxes.
• Summary: Boxes are sold flat, and assembly time is critical, leading manufacturers to focus on ease of setup to reduce labor costs. Domino’s patented box can be folded in about five seconds, saving over 1,200 labor hours daily given their 1.5 million daily deliveries. Westrock even hosts a competition for the fastest pizza box folder.

Consumer Experience Flaws

• Key Takeaway: Despite engineering efforts for logistics, the fundamental design of the pizza box traps steam, which degrades the bread quality and can impart a cardboard aftertaste to the pizza.
• Summary: Scott Wiener notes that the box is inherently bad for pizza because bread and humidity are enemies, trapping steam that causes sogginess. Inventors have proposed numerous re-engineered concepts, including boxes that convert into storage containers or tables. The most brilliant design seen by Wiener utilized indirect ventilation channels within the fluted medium to manage steam.

Recycling Myths and Economics

• Key Takeaway: The common advice that greasy pizza boxes cannot be recycled is a myth; most municipalities allow grease-stained cardboard to be recycled as Old Corrugated Cardboard (OCC).
• Summary: Contamination from cheese, sauce, and packets often leads to pizza boxes being thrown away, despite cardboard being recyclable up to seven times, grease and all. Recycled OCC is sold on the spot market, and its low current value (as low as $30 a ton) benefits manufacturers like Westrock who use it to create new paper products.
