The origin of kraft paper bags: as early as the 19th century when the large-scale retail industry was not yet born, people usually purchased all daily items in grocery stores near their work or residence. It is a headache how to sell those daily necessities to consumers after they are packed in wooden barrels, cloth bags or wooden cases and transported in large quantities to grocery stores. 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 linen head, which were of poor quality and rare quantity, and even could not meet the needs of newspaper printing. Around 1844, German Friedrich Kohler invented wood pulp papermaking, which greatly promoted the development of the paper industry and indirectly gave birth to the first commercial paper bag in history. In 1852, Francis Waller, an American botanist, invented the first paper bag making machine, which was later extended to France, Britain and other European countries. Later, the birth of plywood paper bags and the progress of paper bag sewing technology made cotton bags used for bulk cargo transportation replaced by paper bags. The emergence of shopping Kraft paper bags: when it comes to the first shopping Kraft paper bag, it was born in 1908 in St. Paul, Minnesota, USA. Walter duvina, a local grocery store owner, began to look for ways to enable consumers to buy more things at once in order to promote sales growth. Duvina believes that it should be a prefabricated bag with low cost and ease of use, and can bear at least about 75 pounds. After repeated experiments, he locked the texture of this bag on kraft paper because it was made of conifers with longer wood fibers, in the cooking process, the original strength of the wood fiber is less damaged due to the treatment of caustic soda and sodium sulfide chemicals with mild chemical action, thus the paper finally produced is tightly connected with the fibers, the paper is tough and can withstand large tension and pressure without breaking. Four years later, the first shopping Kraft paper bag was born. Its bottom is rectangular and has a larger volume than the traditional V-shaped bottom paper bag. A rope runs through the bottom and both sides to increase its load-bearing capacity, and two pull rings are formed at the upper end of the paper bag for people to lift. Duvina named the shopping bag after himself and applied for a patent on 1915. At this time, the annual sales volume of this kind of shopping bag has exceeded 100. The appearance of kraft paper bags has changed people's traditional thinking that the amount of shopping can only be limited to the number of items that can be carried by both hands, and has also made consumers no longer reduce the pleasant experience of shopping themselves because they are worried that they cannot take it. If the birth of kraft paper bags has promoted the development of the entire retail industry, it may be exaggerated, but it at least reveals such a phenomenon to the merchants, that is, you can't predict how many things consumers will buy until their shopping experience becomes as comfortable, relaxed and convenient as possible. It is also this point that has aroused the attention of the latecomers to the shopping experience of consumers, and also promoted the development of supermarket shopping baskets and shopping carts. In the following half-century, the development of kraft paper shopping bags has been smooth, and the improvement of materials has continuously enhanced its bearing capacity and made its appearance more beautiful, manufacturers printed various trademarks and patterns on kraft paper bags and entered the shops in the streets. Until the middle of the 20th century, the emergence of plastic shopping bags became another major revolution in the history of shopping bags. Its advantages of being thinner, stronger and cheaper in manufacturing cost have overshadowed the kraft paper bag that was once popular. Since then, plastic bags have become the first choice for daily consumption, while leather bags have gradually 'taken a back seat '. Finally, Kraft paper bags that have passed away can only be used in the name of 'nostalgia', 'nature' and 'environmental protection' in the packaging of a few skin care products, clothing, books and audio-visual products.
