Development history of kraft paper bags

Kraft paper packaging bag is a composite material or pure kraft paper packaging container, non-toxic, odorless, non-polluting, low-carbon and environmentally friendly, in line with national environmental protection standards, with high strength and high environmental protection, is currently the most popular environmentally friendly packaging material in the world one.

The kraft paper packaging bag is made of all wood pulp paper, and the color is divided into white kraft paper and yellow kraft paper. PP paper can be used to coat a layer of film to play a waterproof role. The bag strength can be made from one to six according to customer requirements Layer, printing and bag making integration. The opening and back cover are divided into heat seal, paper seal and lake bottom.

Speaking of the first kraft paper shopping bag, it was born in St. Paul, Minnesota, USA in 1908. Walter Duvina, a local grocery store owner, began to look for ways to allow consumers to buy more at once in order to promote sales growth. Duvina believes that it should be a prefabricated bag, low cost and easy to use, and at least can bear a weight of about 75 pounds. After repeated trials, he locked the texture of the bag on kraft paper, because it was made of conifer tree pulp with longer wood fibers, and was treated by milder caustic soda and sulfide alkali chemicals during cooking, making The original strength of the wood fiber is less damaged, so the final paper produced is tightly connected between the fibers and the paper is tough and can withstand greater tension and pressure without breaking. Four years later, the first shopping kraft paper bag was born. Its bottom is rectangular, which has a larger volume than the traditional V-shaped bottom paper bag. A rope runs through the bottom and both sides to increase its load-bearing capacity, and two pull tabs are formed on the upper end of the paper bag for people to carry. Duvina named this shopping bag under his own name and applied for a patent for it in 1915. At this time, the annual sales volume of such shopping bags has exceeded 100 million.

The appearance of kraft paper bags has changed the traditional thinking that people’s shopping volume can only be limited to the number of items that can be carried by both hands, and it also makes consumers no longer worry about the shopping experience because they are not able to take it. If the birth of kraft paper bags promotes the development of the entire retail industry, it may be exaggerated, but it at least reveals to the merchant that before the customer’s shopping experience becomes as comfortable, relaxed and convenient as possible, you simply It is impossible to predict how much consumers will buy. It is precisely this that has caused the latecomers to attach importance to the shopping experience of consumers, and also promoted the development of later supermarket shopping baskets and shopping carts.
