Read the passageThe peper bag is an interesting invention. Before paper bags were invented, the seller had to wrap goods in paper and tie it with string. Other customers had to wait. Then they hired boys to make bags by hand, but this also took a long time. In 1884, a woman named Mattie Knight invented a machine that could make a bag with a square bottom and pleated sides. The bag stands up, but it can also lie flat. The seller just shakes her wrist to open the bag. Because the bag stands up, it is easy to put things in it.
