About the paper bag machine

In 1868, while Margaret Knight worked in a paper bag machine plant she thought of the idea of making the paper bag bottoms flat to make packing easier. Soon after she invented the machine to make the flat bottom bags. That idea inspired Margaret to create the machine that would transform her into a famous woman inventor. Knight's machine automatically folded and glued paper-bag bottoms, therefore; creating the flat-bottom paper bags that are still used to this very day. A man named Charles Annan tried to steel Margaret's idea of the paper bag so she went to court to prove that it was her idea. Margaret's invention still continues, but keeps improving throughout the years.

Importance of the paper bag machine

The paper bag machine was important because they were used to make paper bags which were used primarily in grocery stores. They were also important because people used them for other needs like packing their lunch, arts, crafts, mailing, and etc. In the past the bags were shaped like a envelope, which made it difficult to put stuff in. Since her brilliant invention that made the bottoms flat and wide, we are able to neatly pack and stack our belongings in, hence; improving our way of life.
