Vacuum packaging cycle
How to obtain a maximum end vacuum in only 4 steps?
1. Extraction of air
Vacuum packaging is an efficient way to extend the shelf life of food products and to protect food against external elements. The cycle has 4 steps. During the first phase, the air is extracted from the product, the bag and the chamber. Up until the pre-set time or vacuum percentage has been reached or the boiling point has been detected in the case of liquid products.

2. Gas flush (option)
Gas flush is an option on all series, except the Jumbo models. Adding a gas offers extra protection and prevents the product from colouring. It's usually a mixture of gas, depending on the product. Your supplier can inform you best which is the optimum mixture for your requirements.
- Increased shelf life
- Protection of structure
- Preservation of quality
- Prevention of colouring
3. Sealing of the bag
The right seal system protects products efficiently against external elements. Depending on the type and thickness of the vacuum bag, and your specific packaging requirements of course. These are Henkelman's seal systems:
- Double seal (standard)
- Cut-off seal ($0)
- Wide seal ($0)
4. Aeration
Once the vacuum packaging cycle has been completed and the vacuum bag has been sealed, air returns into the chamber through the aeration valve. As soon as the atmospheric pressure inside equals the pressure outside the vacuum chamber, the lid opens. This works through normal aeration and Soft Air. Particularly suitable for products with sharp edges.
