Vacuum sealing equipment is designed to remove air from specially designed bags or containers, creating a vacuum-sealed environment that preserves the freshness and longevity of food or other materials. These machines use suction to extract air and then heat-seal the bag, preventing oxygen, moisture, and contaminants from entering. Vacuum sealers are commonly used for food storage, keeping items fresh for longer by slowing down the spoilage process. They are also used to protect non-food items from rust, corrosion, or oxidation.
