Who Invented the Flat Bottom Paper Bag?

Margaret Knight was a remarkable inventor who designed the machine that revolutionized the paper bag industry. Her invention was granted a patent in 1871, and it paved the way for the modern paper bag design that we still use today.

Before Knight’s invention, paper bags were simple and relatively weak. They had no flat bottom, so they couldn’t stand upright on their own, and they had limited capacity. Knight’s machine changed all that. It could produce sturdy paper bags with a flat bottom that could stand upright and hold more items.

Knight’s machine was incredibly advanced for its time. It featured a series of rollers and blades that could cut and fold paper with incredible precision. The machine could produce up to 300 bags per hour, which was a huge improvement over the manual methods that were used at the time.

Knight’s invention was so successful that she went on to start her own company, the Eastern Paper Bag Company. Her invention transformed the paper bag industry, making it possible to produce sturdy, high-capacity bags that could be used for a wide range of purposes. Her legacy as an inventor and innovator is still celebrated today.
