Scope of application

Chemical raw materials, food, pharmaceutical additives, building materials, supermarket shopping, clothing, etc. are all suitable for the industry of kraft paper packaging.

1: According to the material can be divided into: a. Pure kraft paper bags; b. Paper aluminum composite kraft paper bags (cow

Kraft paper bags are popular because of their environmental protection characteristics. Especially in European countries, almost all kraft paper bags are used. Then there are several ways of kraft paper bags.

1. Small white kraft paper bags. Generally, these bags are large in quantity and widely used. Many merchants require this kind of kraft paper bags to be cheap and durable. Usually, the practice of this kraft paper bag is machine molding, and the machine is attached by rope. Machine operation.

2. The practice of medium-sized kraft paper bags. Normally, medium-sized kraft paper bags are made of kraft paper bags made by machine after sticking synthetic type, and then manually affixed with rope. The bag sticking machine can only stick the ropes of smaller handbags, so the practice of kraft paper bags is limited by the machine. Many bags have no way to make the machine unique.

3. Large bags, kraft paper bags with reverse heads, thick yellow kraft paper bags, these kraft paper bags are made by hand. At present, there is no machine in China that can solve these kraft paper bag forming. It can only be made by hand. The production cost of kraft paper bags is relatively high, and the quantity will not be very large.

4. Regardless of which kind of kraft paper bag is used above, if the quantity is not large enough, it is usually made by hand. Because the machine makes kraft paper bags with large losses, there is no way to solve the practice of small quantities of kraft paper bags. ^[1]

As early as the 19th century when large-scale retail was not born, people usually purchased everything in grocery stores near their work or residence. After those daily necessities are packed in wooden barrels, cloth bags or wooden boxes, and they are transported to the grocery store in bulk, how to sell them to consumers is a headache. People can only go shopping with baskets or homemade linen bags. At the time, the raw materials for papermaking were still jute fibers and old linen heads, which were of low quality and scarce quantities, and could not even meet the needs of newspaper printing. Around 1844, the German Friedrich Kohler invented the wood pulp papermaking technology, which greatly promoted the development of the paper industry and indirectly gave birth to the first commercial paper bag in history. In 1852, American botanist Francis Waller invented the first paper bag making machine, which was subsequently promoted to European countries such as France and Britain. Later, the birth of plywood paper bags and advances in paper bag sewing technology made cotton bags used for bulk cargo transportation to be replaced by paper bags.

When it comes to the first kraft paper bag for shopping, it was born in St. Paul, Minnesota, USA in 1908. One local grocery store owner, Wald Duvena, has begun to look for ways to allow consumers to buy more at one time in order to boost sales. Duvina believes that it should be a pre-made bag that is low in cost and easy to use, and can bear at least about 75 pounds. After repeated experiments, he locked the texture of this bag on kraft paper because it was made from conifers with longer wood fibers, and was treated with milder caustic soda and alkali sulfide chemicals during the cooking process, making The original strength of the wood fiber is less damaged, so the final paper produced is tightly connected with the fiber, and the paper is tough and can withstand large tensile and pressure without breaking. Four years later, the first kraft paper bag for shopping was born. Its bottom is rectangular and has a larger volume than traditional V-bottom paper bags. A rope runs through its bottom and sides to increase its load-bearing capacity, and two pull loops are formed on the upper end of the paper bag for easy lifting. Duvena named the shopping bag in his own name and patented it in 1915. At this time, the annual sales volume of such shopping bags has exceeded 100 million.

The emergence of kraft paper bags has changed the traditional thinking that people can only shop with only the number of items they can carry with their hands, and also makes consumers no longer reduce the enjoyment of shopping because they are worried about not being able to take them. If the birth of kraft paper bags has promoted the development of the entire retail industry, it may be a bit exaggerated, but it at least reveals to the merchant that until the customer's shopping experience becomes as comfortable, easy and convenient as possible, you simply cannot Predict how much consumers will buy. It is precisely this that has caused latecomers to attach importance to the consumer shopping experience, and also promoted the development of supermarket shopping baskets and shopping carts.

In the following half century, the development of kraft paper shopping bags has been smooth sailing. Improvements in materials have increased the load-bearing capacity and the appearance has become more exquisite. Manufacturers have printed various trademarks and patterns on kraft paper. On the bag, enter the shops in the streets. Until the middle of the 20th century, the emergence of plastic shopping bags became another major revolution in the development history of shopping bags. With its advantages of lighter, thinner, stronger and cheaper manufacturing cost, it once eclipsed the once-popular kraft paper bag. Since then, plastic bags have become the first choice for daily consumption, and leather bags have gradually "retreated to the second line." In the end, the kraft paper bags that have disappeared can only be used in the packaging of a few skin care products, clothing and books, audiovisual products under the names of "nostalgia", "nature", and "environmental protection".

However, with the global popularity of the "anti-plastic" wind, environmentalists have turned their attention to the ancient kraft paper bags. McDonald's China has been promoting a kraft paper bag with insulation properties in all stores to hold takeaway foods in 2006, instead of using plastic food bags. This measure has also received positive responses from other businesses, such as Nike, Adidas and other large plastic bag consumers, have begun to use high-quality kraft paper bags to replace plastic shopping bags.
