History of kraft paper bags（1）

As early as the 19th century, before the emergence of large-scale retail, people usually purchased all daily items from grocery stores near their work or residence. It is a headache to sell daily necessities in wooden barrels, bags, or boxes to consumers in bulk after being transported to the grocery store. People can only go shopping with baskets or homemade linen bags. At that time, the raw materials for papermaking were still jute fiber and old hemp cloth, with poor quality and scarce quantity, which could not even meet the needs of newspaper printing. Around 1844, German Friedrich Kohler invented wood pulp Papermaking, which greatly promoted the development of Pulp and paper industry and indirectly gave birth to the first commercial paper bag in history. In 1852, American botanist Francis Waller invented the first paper bag making machine, which was later promoted to various European countries such as France and the United Kingdom. Later on, the birth of plywood paper bags and the advancement of paper bag stitching technology led to the replacement of cotton bags used for bulk cargo transportation by paper bags.
