The precautions for vertical packaging machines are as follows:

1. Reducing packaging costs can save storage and transportation costs for loose products. Such as cotton, tobacco, hemp, etc. Reduce packaging costs by using shrink packaging machines to shrink packaging.

2. It can replace manual packaging. Such as vacuum packaging, fully active bag packaging machines, inflatable packaging, close fitting packaging, isobaric filling, etc.

3. Reduce rest intensity and change rest conditions. The rest intensity of manual packaging is very high. Products with large volume and heavy weight, if packaged manually, are also consumable.

4. Beneficial for workers' rest and protection. For some products that seriously affect health and well-being, hand packaging is harmful to health and well-being.

5. Vertical packaging machines can complete useful packaging. Packaging can obtain packaging with consistent specifications according to the requirements of the packaged goods, and manual packaging cannot guarantee it.
