Scope of application

Chemical raw materials, food, pharmaceutical additives, building materials, supermarket shopping, clothing and other industries are suitable for kraft paper bag packaging.

 

As early as the 19th century, before the birth of the large-scale retail industry, people usually purchase all daily items in the grocery store near their work or residence. It's a headache how to sell the daily necessities to the consumers after they are packed in barrels, bags or wooden boxes and transported to the grocery store in bulk. People can only go shopping with baskets or homemade sacks. At that time, the raw materials of papermaking were still jute fiber and old linen head, which were poor in quality and few in quantity, and could not even meet the needs of newspaper printing. Around 1844, German Friedrich Kohler invented wood pulp papermaking, which greatly promoted the development of paper industry and indirectly gave birth to the first commercial paper bag in history. In 1852, Francis Waller, an American botanist, invented the first paper bag making machine, which was then extended to France, Britain and other European countries. Later, the birth of plywood paper bags and the progress of paper bag stitching technology made the cotton bags used for bulk cargo transportation replaced by paper bags.

 

When it comes to the first kraft paper bag for shopping, it was born in 1908 in Sao Paulo, Minnesota. Walter duvina, a local grocer, started looking for ways to get consumers to buy more at once to boost sales. Duvina believes that it should be a prefabricated bag, cheap and easy to use, and at least able to bear about 75 pounds. After repeated tests, he locked the texture of the bag on kraft paper, because it uses coniferous trees with long wood fiber for pulping, and uses caustic soda and alkali sulfide chemicals with mild chemical action to process in the cooking process, so that the original strength of wood fiber is less damaged, so the paper finally produced is closely connected with paper Tenacity, able to bear large tension and pressure without breaking. Four years later, the first kraft paper bag for shopping was born. It has a rectangular bottom, which has a larger volume than the traditional V-shaped bottom paper bag. A rope runs through its bottom and both sides to increase its load-bearing capacity, and two pull rings are formed at the upper end of the paper bag to facilitate people's carrying. Duvina named the bag after himself and patented it in 1915. At this time, the annual sales volume of this shopping bag has exceeded 100 million.


The appearance of kraft paper bags has changed the traditional thinking that people's shopping volume can only be limited by the number of items that can be carried by their hands, and also made consumers no longer worry about not being able to take them down and reduce the happy experience of shopping itself. If the birth of kraft paper bags has promoted the development of the whole retail industry, it may be exaggerated, but at least it has revealed to businesses that before customers' shopping experience becomes as comfortable, relaxed and convenient as possible, you can't predict how many things consumers will buy at the end of the day. It is precisely this point that has attracted the attention of the later generations to the consumer shopping experience, and also promoted the development of the supermarket shopping basket and shopping cart.


In the next half century,the development of kraft paper shopping bags is smooth. With the improvement of materials, its load-bearing capacity is constantly enhanced, and its appearance is becoming more and more beautiful. Manufacturers printed various trademarks and patterns on kraft paper bags, and entered the shops in the streets. But with the global prevalence of "anti plastic" trend, environmentalists began to focus on the old kraft paper bags. Since 2006, McDonald's China has gradually implemented a kind of kraft paper bag with thermal insulation performance in all stores to hold take out food, in order to replace the use of plastic food bags. This initiative has also received positive response from other businesses, such as Nike, Adidas and other former large plastic bag consumers, have started to use high-quality kraft paper bags to replace plastic shopping bags.
