With the development of new material technology and the improvement of manufacturing technology, the "comeback" kraft paper bag is no longer the same as it was in terms of performance and color variety. For example, in order to store meat, aquatic products, and other goods with a certain amount of moisture, you can use all waste paper to make shopping bags. This kind of shopping bag is made by adding a certain amount of wet strength agent to the recycled pulp, and also spraying environment-friendly oil repellant and degradable resin on the surface of the kraft paper bag.

The birth of the kraft paper bag
Development of kraft paper bag
And when it comes to the first kraft paper bag for shopping, was born in St. Paul, Minnesota, USA in 1908. Walter Duvina, a local grocer, began looking for ways to get consumers to buy more at once to boost sales. Davina believes that it should be a prefabricated bag, which is cheap and easy to use and can bear at least 75 pounds. After repeated experiments, he locked the texture of this bag on kraft paper, because it is made of coniferous trees with long wood fibers, and it is treated with caustic soda and alkali sulfide chemicals with relatively mild chemical effects during the cooking process, making it The original strength of wood fibers is less damaged. Therefore, in the final paper, the fibers are closely connected, the paper is tough, and can withstand large tension and pressure without breaking. Four years later, the first kraft paper bag for shopping was born. It has a rectangular bottom and 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 rings are formed on the upper end of the paper bag for people to carry. Duvina named this shopping bag after himself and applied for a patent for it in 1915. At this time, the annual sales volume of this shopping bag has exceeded 100 million.
In the following half a century, the development of kraft paper bags can be said to be smooth. The improvement of the material has continuously enhanced the load-bearing capacity and the appearance has become more and more exquisite. Manufacturers print various trademarks and patterns on kraft paper bags and enter the shops in the streets and alleys.
