Cold vacuum closing without steam

New closing head + pre-heat for greater sealing reliability. Cold vacuum closing is gaining ground, especially as producers look to reduce steam usage and switch to PVC-free lids. LVS therefore introduces a new closing head for cold vacuum closing, optionally combined with a compact pre-heat unit. Together, they increase sealing reliability for glass jars in the food sector, with less changeover time and lower line complexity.

How does cold vacuum closing work with the new closing head?

The new closing head has been designed with a wider operating range. This allows you to process multiple jar sizes with a single head. That reduces changeovers, spare parts and batch-specific adjustments. Operators benefit from a clearer overview, the line remains available for longer, and you reduce the risk of errors that typically arise from frequent changes. In practice, this means higher utilisation of existing capacity and lower indirect costs, without compromises.

Why does pre-heat add value when using PVC-free lids?

PVC-free lids require tighter temperature control. Our pre-heat brings each lid precisely to the right temperature in advance, allowing the compound to flow optimally and the sealing edge to make uniform contact. The result is a demonstrably better seal. You reduce the risk of leaks, faulty closures and complaints afterwards, and you avoid batches being returned later due to insufficient vacuum. The pre-heat unit is compact, easy to integrate into existing lines, and now also works seamlessly with the new closing head.

What does this deliver on the line?

• Less changeover time: multiple jar formats with one head.
• Greater reliability: stable sealing performance, including with PVC-free lids.
• Lower complexity: fewer component changes, therefore less downtime.
• Higher continuity: fewer unplanned stops and smoother batch flow.

Where can you see the solution?

We will present the cold vacuum closing machine with the new closing head and optional pre-heat for the first time at Empack. Would you prefer to test calmly with your own jars and lids? By appointment, you are welcome at LVS for a demonstration at our factory. Together we review your jar sizes, lid types and objectives, and show how the solution fits into your line and improves your production process.
