Duvina believes that it should be a prefabricated bag that is inexpensive and easy to use, and can hold at least about 75 pounds. After trial and error, he locked the texture of the bag on kraft paper because it was pulped from conifers with longer wood fibers, treated with milder chemicals such as caustic soda and sulfide alkali during cooking, making the The original strength of wood fibers is less damaged, so the final paper produced has tight connections between fibers, and the paper is tough and can withstand greater tension and pressure without breaking. Four years later, the first kraft paper bag for shopping was born. It has a rectangular bottom and has a larger volume than traditional V-bottom paper bags. A rope runs through its bottom and sides to increase its load-bearing capacity, and two pull loops are formed on the upper end of the paper bag for people to carry. Duviner named the shopping bag after himself and patented it in 1915. At this time, the annual sales of such shopping bags have exceeded 100 million. Oh, the original raw material of kraft paper is conifer pulp, not cowhide.
