(1) Vacuum packaging machines can produce uniformly sized packages according to the required shape and dimensions based on the items being packaged, which cannot be guaranteed with manual packaging. This is particularly important for export goods, as only vacuum-packaged products can achieve standardized and uniform packaging that meets the requirements of collective packaging.

(2) Capable of performing operations that manual packaging cannot achieve. Some packaging tasks are impossible to accomplish by hand and can only be achieved through vacuum packaging.

(3) Reduces labor intensity and improves working conditions. Manual packaging is highly labor-intensive; for instance, packaging large and heavy products by hand is both physically exhausting and unsafe. For small and lightweight products, the high frequency and repetitive motions can easily lead to occupational diseases among workers.

(4) Beneficial for worker health protection. For products that severely impact health, such as those with high dust levels, toxicity, irritants, or radioactivity, manual packaging inevitably poses health risks. Mechanical packaging, however, can avoid these hazards and effectively prevent environmental pollution.

(5) Reduces packaging costs and saves storage and transportation expenses. For loose products like cotton, tobacco leaves, silk, and hemp, using compression packaging machines to compress and bundle them can significantly reduce volume, thereby lowering packaging costs. At the same time, the greatly reduced volume saves storage space, cuts down on maintenance costs, and facilitates transportation.

(6) Ensures reliable product hygiene. For packaging of items like food and pharmaceuticals, manual packaging is not permitted under health regulations due to the risk of contamination. Vacuum packaging avoids direct human contact with food and drugs, ensuring hygiene quality.
