It typically consists of a chamber, a vacuum pump, and a sealing mechanism. When in use, products are placed inside the chamber. Once the door is closed, the vacuum pump starts working to extract air from the chamber, creating a low-pressure environment. This process effectively removes oxygen and other gases around the products, which helps to significantly extend their shelf life.

After the air is removed, the sealing mechanism quickly seals the packaging material tightly, ensuring that no air can re-enter. It can handle various types of products, from food items like meats, cheeses, and dried fruits to non-food products like electronic components. With its precise operation and reliable performance, the vacuum packaging machine has become an essential tool for many manufacturers and businesses, enabling them to preserve product quality and enhance storage and transportation conditions.
