Development prospects of brown paper bags:

The appearance of brown paper bags has changed the traditional thinking that the amount of shopping can only be limited to the amount of things that can be carried in both hands, and also made consumers no longer worry about not carrying it, which reduces the pleasure of shopping itself. It may be an exaggeration to say that the brown paper bag boosted retail as a whole, but it at least revealed to businesses that it is impossible to predict how many things consumers will buy until the shopping experience becomes as comfortable, relaxed and convenient as possible. It is precisely this point that causes the later-comers to attach importance to consumer shopping experience, and also promotes the development of supermarket basket and shopping cart later.

In the following half a century, the development of brown paper shopping bags can be said to be smooth, the improvement of the material makes its bearing capacity continuously enhanced, the appearance has become more and more exquisite, manufacturers printed all kinds of trademarks, patterns on brown paper bags, into the shops and shops in the streets. Until the middle of the 20th century, the emergence of plastic shopping bags became another large revolution in the development history of shopping bags. It is thinner, stronger and cheaper to make advantages such as the once popular brown paper bag eclipsed. Since then, plastic bags have become the first choice of daily consumption, while cowhide bags have gradually "retreated to the second line". Finally, the faded brown paper bag can only be used in the name of "nostalgia", "nature", "environmental protection" in a few skin care products, clothing and books, audio and video products packaging.

But as the anti-plastic trend spreads around the world, environmentalists are turning their attention to the old brown paper bag. Since 2006, McDonald's China has gradually introduced a insulated brown paper bag for takeaway food in all its outlets, replacing the use of plastic food bags. The move has been echoed by other retailers, such as Nike and Adidas, which used to be big consumers of plastic bags, and are replacing plastic shopping bags with high-quality brown paper ones.
