Ultrasound seals paper-based packaging

Together with the packaging service provider Verdesoft, Herrmann Ultraschall has developed a paper-based cup and a tube that can be sealed using ultrasound.

Together with the packaging service provider Verdesoft, Herrmann Ultraschall has developed a paper-based cup and a tube that can be sealed using ultrasound.

The new packaging concepts offer product protection comparable to that of conventional plastic packaging and save up to 75 per cent plastic in.

The advantages of ultrasonic sealing are also available for paper-based packaging. The cold tools do not damage the paper and only heat the sealing layer. The amount of energy introduced can be precisely parameterised.

„Ultrasonic technology can deliver good sealing results even with narrow process limits. This mainly concerns tightness and optics.“ Robert Hueber, Head of the Packaging Division at Herrmann Ultraschall
