Paper bag machine development history:
        The paper bag machine has been developed with the continuous emergence of new packaging materials and the continuous innovation of packaging technology. The papermaking technology invented in China has historically provided conditions for the production of paper packaging. World paper prices fell sharply in 1850, and paper packaging began to be used in food. In 1852, Worley in the United States invented a paper bag machine, which led to the emergence of paper products machinery. In 1861 Germany established the world's first packaging machinery factory. In 1890, the United States began producing liquid filling machines, and in 1902 it produced gravity filling machines. At the beginning of the 20th century, Durand in the United Kingdom used metalware to preserve food, resulting in a variety of canned foods.
        Since the 1960s, new materials have gradually replaced traditional packaging materials, especially after the use of plastic packaging materials, the paper bag machine has undergone major changes. The rise of supermarkets has placed new demands on the packaging of goods. In order to ensure the fast and safe transportation of goods, the container came into being, and the size of the container body gradually realized standardization and serialization, which promoted the further improvement and development of the paper bag machine.
         Paper bag machine use introduction:
         Packaging is a necessary condition for products to enter the circulation field, and the main means of achieving packaging is the use of packaging machinery. With the development of the times and the advancement of technology, packaging machinery is playing an increasingly important role in the packaging field.
        Its main role is as follows:
        (1) can greatly improve labor productivity. The mechanical packaging of sliding plastic sealing machine is much faster than manual packaging. For example, candy packaging, manual sugar can only pack more than 10 pieces in 1 minute, and candy packaging machine can reach hundreds or even per minute. Thousands of pieces, increasing efficiency by dozens of times.
        (2) It can effectively guarantee the quality of packaging. According to the requirements of packaging articles, according to the requirements of the packaging materials, the packaging materials with the same specifications can be obtained, and manual packaging cannot be guaranteed. This is especially important for export goods. Only mechanical packaging can achieve standardization and standardization of packaging, and meet the requirements of collective packaging.
         (3) It can realize the operation that cannot be realized by manual packaging. Some packaging operations, such as vacuum packaging, pneumatic packaging, body packaging, isostatic filling, etc., are all impossible to achieve by manual packaging, and can only be realized by mechanical packaging.
         (4) It can reduce labor intensity and improve labor conditions. The labor intensity of manual packaging is very high. For example, it is labor-intensive and unsafe to use manual packaging for large and heavy products. For light and small products, due to high frequency, The monotonous movements make it easy for workers to get occupational diseases.
        (5) Labor protection for workers For certain products that seriously affect the health of the body, such as dusty and toxic products, irritating and radioactive products, it is inevitable to endanger the health by hand packaging, while mechanical packaging can be avoided. It can effectively protect the environment from pollution.

         (6) It can reduce the packaging cost and save the storage cost. For loose products, such as cotton, tobacco, silk, hemp, etc., it can be compressed and packed by compression packaging, which can greatly reduce the volume and reduce the packaging cost. At the same time, due to the large size reduction, saving storage capacity, reducing storage costs, and facilitating transportation.
