DUSSELDORF, GERMANY — Bosch Packaging Technology has introduced its extended ultrasonic sealing technology portfolio for all pack styles produced with both horizontal and vertical wrapping systems. It is designed to work with pack styles for food, confectionery and pharmaceutical industries where thermo-sensitive products are common. The introduction happened at interpack 2011, a trade fair for the packaging sector and related processing industries that is going on May 12-18 in Dusseldorf.
Equipping machines with ultrasonic sealing capabilities allows manufacturers to use less energy than heat sealing because jaws do not need to be preheated and film is heated only in the precise sealing area, according to Bosch Packaging Technology. Machines equipped with ultrasonic sealing also may use more cost-effective film and they require thinner seams, which saves material.
“Sustainability is a buzzword in the packaging industry that is continuing to grow in importance,” said Bernd Wilke, head of research and development for Bosch Packaging Technology. “Ultrasonic sealing not only reduces energy usage, saves material and increases machine availability, but also saves production costs so manufacturers can be greener and more profitable.
“We’re pleased to make this innovative technology more readily available to our customers through its incorporation into various machine types.”
