Tubes

Reduction of material and weight with ultrasonic technology

Plastic tubes can be found in the fields of cosmetics, food, but also technology. 
SONOTRONIC has already realized various projects in tube sealing with ultrasonic, for example, a joint development with the company Tubex_Wasungen: a tube without a shoulder is welded with ultrasonic.

Compared to conventional tubes, the SL-T® shoulderless tube from Tubex Wasungen saves up to 40 % of material. At the same time, the ultrasonically welded cap forms a homogeneous unit with the tube, thus avoiding unwanted residues in the cap and opening up new possibilities in tube design for the tube manufacturer. The shoulderless tube thus enables the realization of ecological, functional, sustainable and, above all, cost-conscious packaging. The production process and the diverse design possibilities of the tube have already received several awards, including the German Packaging Award.

In addition, the tube sealing unit from SONOTRONIC seals the ends of tubes securely and tightly.
