Early in the 19th century, large-scale retail trade is not yet born, people usually working or living near the grocery store to buy all day-to-day items. Those daily necessities is loaded in the cask, bag or wooden box, bulk shipped to grocery store, how they are scattered to be sold to consumers, but it is something of a headache. One can only holding a basket of homemade linen bag to go shopping. Papermaking raw materials at the time still jute fibers and old linen head, poor quality and scarce, and can not even meet the demand for newspaper printing. After 1844 years ago, the German Friedrich Kohler invented the wood pulp papermaking, contributed greatly to the development of the paper industry, but also indirectly gave birth to the first in the history of commercial paper bag. In 1852, American botanist Francis Waller invented the first paper bag making machine, it was subsequently extended to France, the United Kingdom and other European countries. Then, the birth of plywood paper bags and paper bags stitched advances in technology makes it the past cloth bag for bulk cargo transport paper bag the alternative.
And it comes to shopping with brown paper bags, which was born in 1908 in St. Paul, Minnesota, USA. A local grocery store owner Walter Du Weina, in order to promote sales growth, began looking for a way to allow consumers to buy more things at once. Du Weina think that should be a good bag of a prefabricated low-cost and easy to use, and at least be able to withstand the weight of about 75 pounds. After repeatedly after the test, he will lock the texture of this bag in kraft paper, because of its long conifer wood fiber pulp by chemical interaction in the cooking process, the more moderate caustic soda and sodium sulfide chemical processing, making smaller damage to the original strength of the wood fiber, paper, fiber, thus finally produced a close connection between the paper tough, able to withstand greater tension and pressure without rupture. Four years later, the first shopping kraft paper bags born. Its bottom is rectangular, having a greater volumetric capacity than the conventional V-bottom paper bag. The rope runs through the bottom and on both sides, in order to increase its load-bearing capacity, and the in paper bag upper end of the formation of two easier for people to lift the pull ring. Du Weina named for this shopping bags in their own name, and applied for a patent in 1915 for its. At this point, this shopping bag has sold more than 100 million years.
The kraft paper bags appear to change the amount of people shopping is only limited by the number of items in his hands can carry conventional thinking, and also allows consumers to reduce no longer fear to take no less than pleasant experience of shopping itself. If before the birth of the brown paper bags to promote the development of the retail sector as a whole, may be somewhat exaggerated, but it at least to the merchant to reveal such a phenomenon, that the customer's shopping experience as comfortable as possible, easy and convenient, you can not predict consumers buy things in the end. It is also a little aroused latecomer to the attention of the consumer shopping experience, and also to promote the later development of supermarket shopping baskets and shopping carts.
After more than half a century, the development of kraft paper shopping bag can be described as smooth sailing, improved materials and constantly enhance its load-bearing capacity, appearance becomes increasingly fine, manufacturers will be printed on a variety of trademarks, logos kraft bag, into the streets of shops shops. Until the mid-20th century, the emergence of plastic shopping bags to become another major revolution in the history of the development of shopping bags. Slimmer, more robust and cheaper manufacturing cost advantage makes kraft paper bags eclipsed once the glory. Since then, the plastic bag to become the first choice of consumption, and leather bags gradually take a back seat. Finally, the famous scenic, passing kraft paper bags only under the guise of "nostalgia", "natural", "green" in the name is used in a small number of skin care products, clothing and books, audio and video products packaging.
