Who invented the paper bag?
While the inventor of the paper bag is lost to obscurity, the invention of the bag’s square bottomed design is widely accredited to one Luther Childs Crowell of Wellfleet in Massachusetts.

When was the paper bag invented? While Crowell’s flat-bottomed bag appeared in the 1870s, one Francis Wolle, a US schoolteacher, invented the first machine to mass-produce these bags as early as the 1850s. Wolle and his brother patented the machine and founded the Union Paper Bag Company, which leads us nicely to how paper bags are made.
How are paper bags manufactured?
Paper bags are manufactured from paper pulp, which is pressed into flat sheets or rolls of paper. These rolls of paper are cut to size, that means twice the required height of the finished bag. These cut sheets are then folded over and the two parallel open sides glued together. This can either be by pressing the glues sides together or heating and pressing.
