Manufacturers can pack products well by using paper bag machines, so paper bag machines are very important for manufacturers. When using the paper bag machine, in order to be able to more clearly understand its importance, we can first understand its development process, which will help us to better play the role of the paper bag machine.
The papermaking technology invented by China has historically provided conditions for the production of paper packaging. In 1850, the world price of paper plummeted, and paper packaging began to be used for food. In 1852, Wally in the United States invented the paper bag machine, and thus paper products machinery appeared. In 1861, Germany established the world's first packaging machinery factory, and in 1911 produced a fully automatic forming, filling and sealing machine.
The United States began to produce liquid filling machines in 1890, and gravity filling machines were produced in 1902. At the beginning of the 20th century, Durand in England used metal containers to store food, and various canned foods appeared.
Since the 1960s, new materials have gradually replaced traditional packaging materials, especially after the use of plastic packaging materials, packaging machinery has undergone major changes. The rise of supermarkets has put forward newer requirements for the packaging of goods. In order to ensure the fast and safe transportation of goods, containers were born, and the size of the container body has gradually realized standardization and serialization, which promotes the further improvement and development of packaging machinery.
The role of packaging machinery
Packaging is a necessary condition for products to enter the circulation field, and the main means to achieve packaging is to use packaging machinery. With the development of the times and technological progress, packaging machinery is playing an increasingly important role in the packaging field.
Its main functions are as follows:
(1) It can greatly improve labor productivity. The mechanical packaging of the sliding table blister sealer is much faster than manual packaging. For example, for candy packaging, manual sugar can only be wrapped in a dozen pieces per minute, while candy packaging machines can reach hundreds or even hundreds of pieces per minute. Thousands of dollars, increasing efficiency dozens of times.
(2) It can effectively guarantee the quality of packaging. Mechanical packaging can obtain packaging with the same specifications according to the requirements of the packaged goods, according to the required shape and size, but manual packaging cannot be guaranteed. This is particularly important for export commodities. Only mechanical packaging can achieve the standardization and standardization of packaging and meet the requirements of collective packaging.
(3) Able to realize operations that cannot be achieved by manual packaging. Some packaging operations, such as vacuum packaging, inflatable packaging, skin packaging, and isobaric filling, cannot be achieved by manual packaging and can only be achieved by mechanical packaging.
(4) It can reduce labor intensity and improve labor conditions. The labor intensity of manual packaging is very large. For example, manual packaging of large and heavy products consumes energy and is not safe; for light and small products, due to the high frequency, Monotonous actions can easily cause workers to get occupational diseases.
(5) Labor protection that is beneficial to workers. For certain products that seriously affect health, such as severely dusty, toxic products, irritating, and radioactive products, manual packaging will inevitably endanger health, while mechanical packaging can be avoided, and Can effectively protect the environment from pollution.
(6) It can reduce packaging costs and save storage and transportation costs. For loose products, such as cotton, tobacco, silk, hemp, etc., compressing and packaging using a compression packaging machine can greatly reduce the volume and reduce packaging costs. At the same time, because the volume is greatly reduced, the storage capacity is saved, and the storage cost is reduced, which is beneficial to transportation.
(7) It can reliably ensure that the product is hygienic. Some products, such as the packaging of food and medicine, are not allowed to be manually packaged according to the Sanitation Law because they will contaminate the product. Mechanical packaging avoids direct contact with food and medicine by human hands. Hygiene quality.
(8) Packaging machinery is a comprehensive science that can promote the development of related industries. It involves many disciplines such as materials, technology, equipment, electronics, electrical appliances, and automatic control. It requires all related disciplines to develop in a synchronized and coordinated manner. The problems will affect the overall performance of packaging machinery.

Therefore, the development of packaging machinery will effectively promote the progress of related disciplines. In addition, in order to meet the needs of high-speed packaging by packaging machinery, the related front and back processes are bound to adapt to it, which promotes the simultaneous development of related processes.
