The Technology

Combitool Solutions’ STN Top Sealer protects tubes and their contents against tampering. Food and pharmaceutical products with screw-on caps, in particular, often require this special protection.

In today’s market, customers increasingly demand sealed tubes to ensure that the contents are fresh and have not been tampered with.

Combitool Solutions’ flexible top sealing system can be integrated into all types of tube production lines.


The STN Top Sealer cuts the seal from a foil and welds it to the plastic tube head in just one process.

This top sealer is highly versatile and can be adapted to any tube production line. Directly integrated with heading or capping stations, it provides high reliability and quality in everyday operation.
