How To Make K Paper Bags?

2.The practice of medium-sized KRAFT paper bags, under normal circumstances, medium-sized KRAFT paper bags are made of KRAFT paper bags made by hand-pasting ropes after being pasted by machines, because the domestic KRAFT paper bag forming equipment is limited by the molding size, and the KRAFT paper bag rope sticking machine can only paste the rope of smaller handbags, so the practice of KRAFT paper bags is limited by the machine. There are many bags that cannot be made by the machine alone.
3.Large bags, KRAFT paper bags with reverse heads, thicker KRAFT paper bags, the practice of these KRAFT paper bags should be made by hand, there is no domestic machine that can solve the molding of these KRAFT paper bags, can only be made by hand, the production cost of this kind of KRAFT paper bags is higher, and the number will not be very large.

New Development Prospects About Bags As KRAFT Papers
The emergence 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 has also made consumers no longer worry about not being able to take it and reduce the pleasant experience of shopping itself. It may be an exaggeration to say that the birth of the KRAFT paper bag has driven the entire retail industry forward, but it at least reveals to merchants that you simply can’t predict how much consumers will buy until their shopping experience becomes as comfortable, easy and convenient as possible. It is precisely this point that has attracted the attention of latecomers to the consumer shopping experience, and at the same time promoted the development of supermarket shopping baskets and shopping trolleys.
In the following more than half a century, the development of KRAFT paper shopping bags can be described as smooth sailing, the improvement of the material to make its load-bearing capacity continue to increase, the appearance has become more and more exquisite, manufacturers will be a variety of trademarks, patterns printed on KRAFT paper bags, into the streets and alleys of the shops. Until the middle of the 20th century, the emergence of plastic shopping bags became another major revolution in the history of shopping bags. With the advantages of thinner, stronger and cheaper manufacturing costs, it eclipses the once glamorous KRAFT paper bag. Since then, plastic bags have become the first choice for living consumption, while cowhide bags have gradually “taken a back seat”. In the end, the disappearing KRAFT paper bag can only be used in the packaging of a small number of skin care products, clothing, books, and audio-visual products under the pretense of “nostalgia”, “nature” and “environmental protection”.
But with the global prevalence of “anti-plastic” trends, environmentalists are turning their attention to ancient KRAFT paper bags. Since 2006, McDonald’s China has gradually implemented a kind of KRAFT paper bag with thermal insulation performance to hold takeaway food in all stores, instead of using plastic food bags. This initiative has also received a positive response from other businesses, such as Nike, Adidas and other large consumers of plastic bags, have begun to use high-quality KRAFT paper bags to replace plastic shopping bags.
