production method

kraft paper bags are favored by people because the software can set limit alarm and shutdown protection as its environmental protection features. Especially in European countries, almost all kraft paper bags are used. How many methods are there for kraft paper bags

1. Small white kraft paper bags. Generally, this kind of bag has a large number and a wide range of applications, because many businesses require this kind of kraft paper bag to be cheap and durable. Usually, this kind of kraft paper bag is machine formed, machine attached, and completely operated by machines

2. The practice of medium-sized kraft paper bags. Usually, medium-sized kraft paper bags are made by manually pasting ropes after machine fitting and forming. Because the current domestic kraft paper bag forming equipment is limited by the molding size, and the kraft paper bag pasting machine can only paste ropes of smaller handbags, the practice of kraft paper bags is limited by machines. Very 2.1 bags with many proprietary and unique computer control systems cannot be produced by the machine alone

3. Large bags, including reverse kraft paper bags and thick kraft paper bags. These kraft paper bags should be made by hand. At present, there is no machine that can solve the molding of these kraft paper bags in China, so they can only be made by hand. The production cost of this kind of kraft paper bags is high and the quantity will not be large

4. No matter which kind of kraft paper bag above is of great significance to improve the technical level and automation level of China's aluminum purification industry. If the quantity is not large enough, it is generally made by hand. Because the consumption of machine-made kraft paper bags is large, there is no way to solve the practice of small quantity of kraft paper bags
