Until the middle of the 20th century, the emergence of plastic shopping bags became another major revolution in the history of shopping bags.

Since then, plastic bags have become the first choice for daily consumption, while cowhide bags have gradually "retreated to the second line." Finally, the decayed kraft paper bags can only be used in the packaging of a small number of skin care products, clothing, books, and audiovisual products under the name of "nostalgia", "natural" and "environmental protection". In recent years, with the global trend of "anti-plastic", environmentalists have begun to turn their attention to the old kraft paper bags.
