1. It can greatly improve labor productivity. Counting, weighing, and blister sealing packaging are much faster than manual packaging. For example, for hardware accessories packaging, manual packaging may only produce more than 10 packages, while granule packaging machines can produce hundreds of packages per minute, which improves efficiency by dozens of times.

2. It can effectively ensure the quality of packaging. Mechanical packaging can obtain packaging materials with consistent specifications according to the requirements of the packaging items, the required shape and size, which cannot be guaranteed by manual packaging. This is especially important for export commodities. Only mechanical packaging can achieve packaging standardization and standardization, and meet the requirements of collective packaging.

3. It can realize operations that cannot be realized by manual packaging. Some packaging operations cannot be realized by manual packaging and can only be realized by mechanical packaging.

4. It can reduce labor intensity and improve working conditions. The labor intensity of manual packaging is very high. For light and small products, due to the high frequency and monotonous movements, workers are prone to occupational diseases.

5. It is conducive to the labor protection of workers. For some products that seriously affect health, such as products with serious dust, toxic products, irritating and radioactive products, manual packaging will inevitably harm health, while mechanical packaging can avoid it and effectively protect the environment from pollution.

6. It can reduce packaging costs, save labor costs, and reduce costs. At the same time, the neat, regular and beautiful appearance improves customers' aesthetics of the product, thereby increasing sales.

7. Can reliably ensure product hygiene. According to the health law, some products, such as food and medicine packaging, are not allowed to be packaged manually because they will contaminate the products. Mechanical packaging avoids direct contact between human hands and food and medicine, ensuring the hygiene quality.

8. Can promote the development of related industries. Packaging machinery is a comprehensive science, which involves multiple disciplines such as materials, processes, equipment, electronics, electrical appliances, and automatic control. It requires the synchronous and coordinated development of various related disciplines. Problems in any discipline 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 of packaging machinery, its related front and back processes must also adapt to it, which also promotes the synchronous development of related processes.
