The Historical Origin Of Kraft Paper Bag

Kraft paper bag is widely used now, but few people know when and how it came into being. Now let's learn about the history of kraft paper bags!

Kraft paper bag was born in 1908 in St. Paul, Minnesota. There is a local grocer named "Walter duvina" who is looking for ways to make consumers buy more at once in order to boost sales. Duverner believes that a number of bags should be prefabricated, cheap and easy to use, and should be able to withstand at least 75 pounds. After repeated experiments, he locked the material of the bag on kraft paper, because it used conifer pulping with long wood fiber. In the cooking process, it was treated with mild caustic soda and alkali sulfide chemicals, which made the original strength of wood fiber less damaged After the production of paper, fiber connection between the tight, paper tough, can withstand greater tension and pressure without breaking.

After repeated experiments, four years later, kraft paper handbag was born. Its bottom is rectangular, which has a larger volume than the traditional V-bottom paper bag. A rope runs through its bottom and both sides to increase its load-bearing capacity, and forms two pull rings at the upper end of the paper bag for people to carry. Duverner named the bag after himself and patented it in 1915. At this time, the annual sales of these shopping bags have exceeded 100 million.

Now with the continuous development of technology, the craft of kraft paper handbag is more and more perfect, which can meet the needs of all kinds of goods, and has become the first choice of materials when making handbags.
