The emergence of the kraft paper bag as a paper shopping bag has changed the traditional thinking that shopping is limited to the number of items that can be carried by both hands, and has made it less enjoyable for consumers to shop because they are worried about not being able to carry it. This article will focus on the historical change and the future of the kraft paper bag.

What historical changes have kraft paper bags undergone?

The first shopping kraft paper bag, which was born in 1908 in St. Paul, Minnesota, USA. A local grocery shop owner, Walter DuVernay, began looking for ways to get consumers to buy more things at once to boost sales. DuVernay thought it would be a pre-made bag that was inexpensive and easy to use and could hold at least 75 pounds. After much trial and error, he settled on kraft paper, which was made from coniferous trees with long wood fibers and treated with milder chemicals such as caustic soda and sulphuric alkali during the cooking process, so that the original strength of the wood fibers was less compromised, resulting in a paper that was tightly joined and tough enough to withstand high tension and pressure without breaking. Four years later, the first packaging bag for shopping was created. With its rectangular bottom, it has a larger volume than the traditional V-bottom paper bag. A cord runs through its bottom and sides to increase its load-bearing capacity, and two pull loops are formed at the top end of the bag to make it easier for people to carry. Du Weiner named this shopping bag after himself 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 future of kraft paper bags.

It may be an exaggeration to say that the birth of the paper shopping bag has driven the development of the entire retail industry, but it has at least revealed to businesses that you simply cannot predict how much consumers will buy until their shopping experience becomes as comfortable, easy and convenient as possible. This was the point that drew attention to the consumer shopping experience and led to the development of the supermarket basket and trolley.

In the following half-century or so, the development of kraft paper shopping bags can be described as smooth, the improvement of the material to increase its load-bearing capacity, the appearance has become more and more beautiful, manufacturers will be a variety of trademarks, patterns printed on kraft paper bags, into the streets of shops. Until the mid-20th century, the emergence of plastic shopping bags became another large revolution in the history of shopping bag development. It is lighter, thinner, stronger, and cheaper manufacturing costs and other advantages make the once beautiful kraft paper bags eclipsed.

However, with the "anti-plastic" wind prevailing around the world, environmentalists have begun to focus on the old take away paper bags. McDonald's China began in 2006, gradually in all shops to implement a thermal insulation property of take away paper bags to hold takeaway 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, who have begun to use high-quality take away paper bags to replace plastic shopping bags.

Located in Nanjing, China, Nanjing Lipack Co., Ltd is a large manufacturer of kraft paper bags, which has been exporting kraft paper bags to various parts of the world and has received wide acclaim. The company verifies the quality of each product before it leaves the factory to ensure that the consumer's rights are fully protected.

In addition to protecting goods and facilitating storage and transportation, cardboard paper boxes also play the role of beautifying and promoting goods. Cardboard paper boxes belong to green products, it is conducive to environmental protection, loading, and unloading transportation. The next will provide you with a detailed introduction to cardboard paper boxes.

Here is the table of contents:

How is the strength of cardboard paper boxes designed?

1. Side compression strength = surface raw paper comprehensive ring compression strength + comprehensive corrugated paper ring compression strength * shrinkage rate general side pressure calculation according to the lowest ring compression strength of raw paper (safe and reliable), the actual test value will be appropriately greater than the theoretical calculation value.

2. Breaking strength: The maximum external force that a unit area of corrugated board can withstand before rupture is uniformly increased. Unit: Kg/cm2.

Cardboard paper box rupture strength = face paper rupture strength + middle grid paper rupture strength + bottom paper rupture strength

4. Side compression, breakage resistance, puncture with cardboard. Cardboard paper box edge compression strength will be lower than the cardboard edge compression strength (due to the loss of corrugated in the manufacturing process).

5. Cardboard paper box compressive strength = side compression strength (N/cm) * Calicut constant F. The F value depends on the perimeter length of the cardboard paper box, 2*(length + width) cm. and the corrugated flute type.

6. The compressive strength of cardboard paper box = corresponding to the compressive strength of ordinary box type * 0.6 * 1.62 * shaking cover width/carton width.

7. Cardboard paper boxes, cardboard bonding strength. As with corrugated paper boxes, the force is required to separate the unit length of cardboard face paper from the corrugated paper. Unit: N / m flute.

8. Stacking strength and compressive strength.

The required compressive strength of a cardboard paper box = [gross weight of the box * (stacking layers - 1)] * safety factor K. The former part is the static stacking strength of the cardboard paper box.

What are the design principles of the cardboard paper box?

Cardboard paper box structure design is from the actual conditions of packaging and production, based on scientific principles of the packaging shape structure and internal accessories for the design. Design must ensure that the structure has sufficient strength, hardness, and the ability to resist other environments.

Qualified cardboard paper box products start with the right structural design. Designers must not only truly understand the customer's intent, but also be familiar with the post-processing process. Designers should understand the nature, shape, size, and weight of the cardboard paper box contents, the arrangement, transportation, and stacking of the contents, the storage environment of the contents, the transportation route and time, as well as the carton box type and production materials before the design begins. Designers in determining the size of the cardboard paper box are mainly to consider two factors: one is to be able to accommodate the contents; the second is to have sufficient strength. Just like the extensions box, it's internal how can contain enough items on how to design. The constraints of the cardboard paper box size and shape of the factors in addition to the contents of the package, there are many other factors, such as ergonomic factors, the size of the pallet, the size of the truck car, the size of the container space, with the size of the shelf size. Only when the design is carried out so meticulously will it be possible to have holographic paper boxes in the future.

Nanjing Lipack Co., Ltd. will provide comprehensive, full, and precise services for target customers is the customer to get greater value-added and create a win-win situation with customers. At the same time, we need to keep innovating, keep pace with advanced technology, and manufacture new concepts of cardboard paper boxes to serve society.
