First, it can greatly improve labor productivity. Mechanical packaging is much faster than manual packaging. For example, automatic granule packaging machine, normal manual counting packaging, it takes a few minutes to pack a package, and other people are required to assist in packaging, while automatic packaging machine can pack 20-80 packages per minute or even more many.

Second, it can effectively guarantee the quality of packaging. Mechanical packaging can obtain packaging with consistent specifications according to the required shape and size according to the requirements of the packaged items, 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.

 Third, it can achieve operations that cannot be achieved by manual packaging. Some packaging operations, such as automatic coding and packaging, cannot be achieved by manual packaging and can only be achieved by mechanical packaging.

 Fourth, it is beneficial to labor protection for workers for certain products that seriously affect their health. Such as dusty, toxic products, irritating, radioactive products, manual packaging will inevitably endanger health, while mechanical packaging can avoid it and can effectively protect the environment from pollution.

Finally, it can reliably ensure that the product is hygienic for certain products, such as the packaging of food and medicine, because manual packaging will contaminate the product, while mechanical packaging avoids direct contact with food and medicine by human hands, ensuring the quality of hygiene.
