| Production of the Sitka Spruce Butter Tub Begins |
 Even though demand for most types of woodenware is falling, butter tubs are an exception. For most of the 1920s, butter is one of the few products that continues to be sold primarily in wooden packaging. Menasha forms a subsidiary in Tacoma, Washington, called Northwestern Wooden Ware Company, to make staves from Sitka spruce, which are made into butter tubs for local markets. Menasha's Sitka spruce tubs keep butter fresh for up to a year, versus most other tubs made of ashwood that cause the butter to become moldy within six months. Menasha Wooden Ware quickly becomes the number one butter tub manufacturer in the nation. |

| Menasha Wooden Ware Reorganizes |
 Menasha is reorganized into two separate companies. One is called Menasha Wooden Ware Corporation, which continues the marketing and manufacturing operations. The other is called Menasha Wooden Ware Company, which owns a portfolio of stocks. This allows for the portfolio to generate investment income for Menasha shareholders even when manufacturing operations are unprofitable. This structure will endure for the next 55 years. |

| Menasha Enters the Corrugated Business |
 Corrugated board had been developed in the 1870s when the machine that produces corrugating medium (the squiggly center of the board) was invented. By the 1920s, the use of corrugated containers by shippers of consumer and industrial products is increasing. Recognizing opportunity, Menasha sets up a corrugated box plant and has been producing corrugated containers ever since. This part of Menasha is now known as the Packaging Group. |
