External Type Vacuum Packaging Machine

vacuum sealer removes air from the packaging using a suction pump, creating a vacuum inside the bag. It then heat-seals the bag to lock out oxygen and moisture. This process helps prevent spoilage, freezer burn, and oxidation, extending the shelf life of food and other perishable items.

Vacuum sealing offers several advantages:  

- Extends food freshness 3-5 times longer  

- Reduces food waste  

- Saves storage space  

- Protects against bacteria and mold  

- Maintains flavor, texture, and nutritional value

Vacuum sealers are versatile and can be used for:  

- Fresh meats, fish, and poultry  

- Cheese, fruits, and vegetables  

- Dry goods like coffee, nuts, and grains  

- Prepared meals and leftovers  

- Non-food items (electronics, documents, medical supplies)

Consider these factors when selecting a vacuum sealer:  

- Usage: Home, commercial, or industrial needs  

- Vacuum strength: Higher suction for moist foods  

- Sealing speed: Faster models for frequent use  

- Size & portability: Countertop vs. chamber vacuum sealers  

Proper maintenance ensures longevity:  

- Check and replace vacuum pump oil

- Keep the machine free of food debris  

- Store in a dry, dust-free environment  

- Regularly inspect the heat seal bar for wear
