Jun 14, 2017

Kraft paper Bag originated earlier, the first shopping kraft bag, which was born in 1908 in St. Paul, Minnesota. In order to boost sales, a local grocery owner, Walter Duvena, began looking for ways to get consumers to buy more things at once. Duvina believes that it should be a prefabricated bag, cheap and easy to use, and can withstand at least 75 pounds of weight. After further testing, he locked the texture of the bag on Kraft paper because it was made from a coniferous tree with long wood fibres in the cooking process through chemical action more mild caustic soda and sulfide chemical treatment, so that the original strength of wood fiber is less damage, so the final produced paper, fiber connection Close, paper tough, can withstand greater tension and pressure without rupture. In this way, the first shopping with Kraft paper Bag was born. The bottom is rectangular and has a larger volume than the traditional V-shaped bottom paper bag. A rope runs through its bottom and sides to increase its load-bearing capacity and to form two of the pull rings for people to pick up at the top of the paper bag. Duvina named the shopping bag under his name and patented it in 1915. At this point, this shopping bag has more than 100 million annual sales.
