Scope of application
Chemical raw materials, food, pharmaceutical additives, construction materials, supermarket shopping, clothing and other industries suitable for kraft paper bag packaging.
Back in the 19th century, before the birth of large-scale retailing, people usually purchased all their daily necessities at the grocery store near their work or residence. Those everyday items were packed in barrels, bags or wooden boxes, bulk transported to the grocery store, how to sell them piecemeal to consumers, but a headache. People had to go out shopping with baskets or homemade burlap bags. The raw material for paper at that time is still jute fiber and old linen head, poor quality and scarce, and can not even meet the needs of newspaper printing. around 1844, the German Friedrich Kohler invented wood pulp papermaking, greatly promoting the development of the paper industry, but also indirectly gave birth to the first commercial paper bags in history. 1852, the American botanist Francis Waller invented the first paper bag manufacturing machine, which was then extended to France, Britain and other European countries. Then later, the birth of plywood paper bags and the progress of paper bag sewing technology makes the past for bulk cargo transportation of cotton bags were also replaced by paper bags.
And to say that the first shopping with kraft paper bags, it was born in 1908 in St. Paul, Minnesota, the United States. A local grocery store owner Walter DuVernay, in order to promote the growth of sales, began to look for ways to enable consumers to buy more things at once. DuVernay thought it would be a pre-made bag that would be inexpensive and easy to use and would hold at least 75 pounds. After repeated tests, he will be the texture of the bag locked in the kraft paper, because its use of wood fibers longer coniferous pulp, in the cooking process through the chemical effect of milder caustic soda and sulfuric alkali chemicals for processing, so that the original strength of wood fibers are less damaged, and thus the final production of paper, tightly connected between the fibers, tough paper, can withstand greater tension and pressure without breaking. Four years later, the first shopping with kraft paper bags were born. It is rectangular at the bottom, with greater volume than the traditional V-bottom paper bag. A rope through its bottom and sides to increase its load-bearing capacity, and the upper end of the paper bag to form two easy to lift the pull ring. Du Weina named this shopping bag in his name, and applied for a patent for it in 1915. At this time, the annual sales volume of this shopping bag has exceeded 100 million.
The emergence of kraft paper bags changed the amount of shopping can only be limited to the number of items that can be carried by both hands traditional thinking, but also makes consumers are no longer worried about not being able to take and reduce the pleasant experience of shopping itself. If the birth of kraft paper bags to promote the development of the entire retail industry, perhaps some exaggeration, but it at least to the business revealed such a phenomenon, that is, before the customer’s shopping experience becomes as comfortable, easy and convenient as possible, you simply can not predict how much consumers will actually buy things. It was this that drew the attention of later generations to the consumer shopping experience and simultaneously drove the development of later supermarket baskets and shopping trolleys. Image
In the following half century, the development of kraft paper shopping bags can be described as smooth, the improvement of the material to enhance its load-bearing capacity, the appearance has become more and more exquisite, manufacturers will be a variety of trademarks, patterns printed on kraft paper bags, into the streets of stores. Until the mid-20th century, the emergence of plastic shopping bags has become another large revolution in the history of shopping bag development. It is lighter, thinner, stronger and cheaper manufacturing costs and other advantages make once the scenery of kraft paper bags eclipsed. Since then, plastic bags have become the first choice of life consumption, and kraft bags gradually “recede into the second line. Finally, the scenery died kraft paper bags can only pretend to “nostalgia”, “natural”, “environmental protection” in the name of a few skin care products, clothing and books, audio and video products in the packaging.
However, with the “anti-plastic” wind prevailing around the world, environmentalists have begun to look at the old kraft paper bags. McDonald’s China company from 2006, gradually in all stores to implement a thermal insulation properties of kraft paper bags to hold take-out food, to replace the use of plastic food bags. This initiative has also received a positive response from other businesses, such as Nike, Adidas and other large consumers of the original plastic bags, have begun to use high-quality kraft paper bags to replace plastic shopping bags.
