Ultrasonic bag sealing system

No one wants to see materials escaping from incompletely sealed bags. Not only is it a health hazard for your operators and customers, it also means that contaminants could be getting into the bags, putting product quality at risk.

VENTOSEAL CL is an ultrasonic bag sealer suitable for paper, plastic or woven bags. It is designed for both new installations and as a retrofit for existing packing plants of any make or model.


How it works

As your bags are discharged by the packing machine, they remain on the belt conveyor and are precisely aligned ready for treatment. The valve is first cleaned and then sealed with ultrasonic technology.

After the sealing process the bag valve is 100% sealed. Nothing can get in, and no product can escape – giving you a dust-free environment from your plant all the way to the end user, and securing your product quality over the long-term.

Spill-free, dust-free bag handling

High productivity bag sealing

In the past, on-board sealing in the packing machine has resulted in slower output. The VENTOSEAL CL  ultrasonic sealing machine  guarantees full capacity up to 2800 bags/hour. There is no reduction in productivity, and you still get a 100% seal and no dust.


Plug and play concept

There is no need to apply any special device to your new or existing packing machine – the VENTOSEAL CL is a simple, standalone machine. Just plug and play!


Works with any kind of packer

Old or new, FLSmidth or other – you can use the VENTOSEAL CL with any new or existing packing line.


Standalone sealing process

As a standalone process, you can even bypass this machine when ultrasonic sealing is not required.

Valve bag sealing design based on experience

More than 20 years ago, VENTOMATIC® developed the VENTOSEAL H, a mechanical valve closing system based on knurling wheels. The VENTOSEAL CL draws on that experience and our thirst for innovation to deliver a capable, reliable bag sealing system designed for the modern packing plant.


Although it is built to be a standalone system, the ultrasonic technology used in the VENTOSEAL CL can be incorporated into our packing machines as an on-board system where space is limited.
