Kraft paper bag--the history and development

　　Kraft paper bag is made of wood pulp paper as the base material, and the colors are divided into white kraft paper and yellow kraft paper. The paper can be coated with a layer of PP material to play a waterproof role. The strength of the bags can be made into one to six layers according to the requirements of customers, and the printing and bag making are integrated. Opening and sealing methods are divided into heat sealing, wrapping paper and edge.
　　
　　The historical evolution of kraft paper bag
　　Back in the 19th century, before big retail, it was common for people to do all their daily shopping at the grocery store near where they worked or lived. Those daily goods are packed in barrels, cloth bags or wooden boxes, after the bulk transport to the grocery store, how to sell them scattered to consumers, but it is a headache. People had to go shopping with baskets or homemade burlap bags. At that time, the raw materials of paper were still jute fiber and old linen head, which were of poor quality and scarce in quantity, and even could not meet the demand of newspaper printing. Around 1844, German Friedrich Kohler invented wood pulp papermaking, which greatly promoted the development of the paper industry and indirectly spawned the first commercial paper bag in history. In 1852, American botanist Francis Waller invented the first paper bag making machine, which was then popularized to France, Britain and other European countries. Later, with the advent of the plywood paper bag and advances in suture technology, paper bags replaced cotton bags used in the past for bulk transportation.
　　Speaking of the first shopping kraft paper bag, it was created in 1908 in St. Paul, Minnesota. In an effort to boost sales, Walter Duverna, a local grocery store owner, began looking for ways to get customers to buy more at once. Mr. Duverna thought it would be a prefabricated bag that was cheap and easy to use and could hold at least 75 pounds or so. After repeated experiments, he will be the quality of a material of this bag lock on the kraft paper, because it USES the longer conifer wood fiber pulp, in the process of cooking by chemistry more moderate caustic soda and alcali sulphide chemicals processing, make the strength of the original wood fiber damage is small, thus finally made of paper, close connection between fiber, paper is tenacious, Can withstand the larger tension and pressure without breaking. Four years later, the first shopping paper bag was born. It is rectangular at the bottom and has more volume than a traditional V-shaped paper bag. A rope runs through the bottom and sides of the bag to increase its load-bearing capacity, and the top of the bag forms two easy to handle pull rings. Duverna named the shopping bag after himself and patented it in 1915. By this time, more than a million of these bags were being sold annually.
　　
　　The development of kraft paper bag
　　The paper bag has changed the traditional thinking that people can only buy as many items as they can carry with their hands, and it has made it easier for consumers to reduce the pleasure of shopping by worrying about not being able to carry them. It would be an exaggeration to say that the creation of the kraft paper bag propelled the entire retail industry, but it has at least revealed to merchants that it is impossible to predict how much consumers will buy until the shopping experience is made as comfortable, easy and convenient as possible. It was this point that caused the later comers to attach importance to the consumer shopping experience, and also promoted the development of supermarket baskets and shopping carts.
　　Over the next half century or so, kraft paper bags have developed with increasing weight bearing and improved appearance, and manufacturers have printed various logos and patterns on them for use in shops and shops. It wasn't until the middle of the 20th century that plastic shopping bags emerged as another major revolution in the history of shopping bags. It's thinner, stronger and cheaper to make, overshadowing the once-popular kraft paper bag. Since then, plastic bags have become the first choice for living consumption, while kraft paper bags have gradually "taken a back seat". Finally, the kraft paper bag can only be used in a few skin care products, clothing, books, audio and video products under the guise of "nostalgia", "nature" and "environmental protection". But as anti-plastic trends take hold around the world, environmentalists are turning their attention to the ancient kraft paper bag.
