Bi-active sealing designed for vacuum packaging of food and non-food products
A vacuum packer with bi-active sealing working with aluminum bags or bags of extra thickness (more than 180 microns). These types of vacuum bags are the most difficult to package. As a result, the need for bi-active sealing is becoming an essential requirement.
Know-how of sealing technology
The development of sealing technology does not stop there. Contact us for advice. We will help you find the optimal configuration of the sealing types, the necessary sealing pressure, and also offer our recommendations to achieve optimal packaging quality depending on the product and your process.
Using Soft Air, the air is gradually and gently returned into the chamber. This gradual process is based on the pre-set time. In a controlled way, the vacuum bag envelopes the product. For optimal protection of both the product and the vacuum bag.
Soft Air is suitable for both food and non food products. Particularly T-bone steaks, racks of lamb, spare ribs, screws, bolts, electronic components and Printing Circuit Boards (PCB's).
The most popular Henkelman sealing systems. This simple solution offers significant advantages of vacuum packaging.
Comparison of a round seal string and a double sealing system
Most vacuum packers available on the market are equipped with a double sealing system with two flat strings for double joint. Compared to this system, the cut-off string option offers better hygiene, as the operator can easily remove the excess part of the bag and the packaging looks much more aesthetically.
Henkelman Convex Sealing Machine
Helps to achieve the best packaging results. Flat strings, the most common in vacuum packers, crushing of the product residues between the two sides of the bag, which can losing vacuum. Henkelman convex sealing reduces this risk due to higher pressure in the sealing joint
Between the evacuation and sealing cycles, it is optionally possible to inject gas. Often, gas is used to extend shelf life, further protect fragile products, and prevent the loss of natural color near certain products.
The Henkelman inclined insert plate offers convenience if you want to package liquids or powders, such as soups, sauces and flour. Because the vacuum bag can be positioned in the chamber at a certain angle, the product stays precisely at its place.
Available in different sizes and suitable for all models.
Polyethylene inserts in the vacuum chamber are standard on each machines and serve to optimize the duration of the work cycle and adjust the position of the package inside the chamber. For two-chamber models, possible to produce special inserts for the cover to save time and reduce gas consumption by reducing the volume of the vacuum chamber.
