In the 19th century, people often procured everything in the grocery store near work or residence. It is a headache for those daily necessities to be sold in the barrels, bags or wooden boxes, and how to sell them to consumers after being transported to the grocery store. People can only take a basket or homemade linen bag to go shopping. And then the papermaking raw materials are still jute fiber and old linen head, poor quality and scarce, and even can not meet the needs of newspaper printing. Before and after 1844, the German Friedrich Kohler invented the pulp and papermaking, greatly promoted the development of the paper industry, but also indirectly gave birth to the history of the first commercial paper bag. In 1852, the American botanist Francis Waller invented the first paper bag manufacturing machine, which was subsequently extended to France, Britain and other European countries.

& nbsp; Two: Shopping with the emergence of kraft paper bags

A local grocery store owner, Dav Duvina, began to look for ways to get consumers to buy more at one time in order to boost sales. Du Weiner believes that it should be a prefabricated bag, low cost and easy to use, and at least can withstand about 75 pounds of weight. After repeated tests, he locked the texture of the bag on kraft paper because it was made with longer woody pulp, which was treated in the cooking process by relatively mild caustic soda and sulphide chemicals. The original strength of wood fiber damage is small, and thus the final production of the paper, the fibers are tightly connected, paper tough, can withstand greater tension and pressure without rupture. Four years later, the first shopping was born with kraft paper bags. Its bottom is rectangular, than the traditional V-shaped paper bag with a larger volume.

Until the mid-20th century, the emergence of plastic shopping bags to become a shopping bag in the history of another large-scale revolution.

Since then, plastic bags become the first choice for life consumption, and leather bags gradually "relegated to second line." Finally, the scenery of the kraft paper bag can only be under the guise of "nostalgia", "natural", "environmental protection" in the name of a small number of skin care products, clothing and books, audio and video products in the packaging. However, in recent years, with the "anti-plastic" wind prevailing in the world, environmentalists who began to look to the ancient kraft paper [/ p]
