How ultrasonic bonding makes hygiene products more eco-friendly
Legal requirements and changing consumer behavior make sustainable production methods in diaper manufacturing a necessity. At the same time, companies are under pressure to optimize their costs and remain competitive. Ultrasonic welding offers an innovative solution that combines ecological and economic advantages.
Manufacturing adhesive-free hygiene products with ultrasonics
Manufacturers of hygiene products such as diapers are constantly under pressure to reduce costs while delivering high-quality products. One effective long-term method of meeting these requirements is to use ultrasonic bonding instead of conventional adhesives. This efficient joining method offers significant advantages in terms of cost savings, efficiency, and sustainability.
How ultrasonics optimizes the manufacturing of hygiene products
Diapers are an indispensable companion for babies or adults with incontinence problems. In addition to key aspects such as absorbency and leak protection, wear comfort is becoming increasingly important when selecting the right diaper. Consumers are paying more and more attention to products that feel soft on the skin and are comfortable to wear.
The softness of nonwoven materials plays a decisive role here. But how can the softness of the nonwoven material be preserved during the manufacturing of diapers and other hygiene products? Choosing the right bonding process is a key factor.
Ultrasonic welding has established itself as an efficient and precise joining technology in the manufacturing of plastic heat exchangers. It enables the tight, stable and material-friendly connection of components without the use of additional joining agents such as adhesives or screws. This process plays a particularly important role in applications involving aggressive mediums or high demands on tightness.

Automated connection of medical components for maximum output
Perfect for automated assembly: Thanks to minimized welding times and real-time process control, ultrasonics is ideal for manufacturing medical components in high volumes. Find out the advantages of the technology for your application in this article.
Joining Plastics of Medical Devices Without Adhesive
Particularly for medical products with direct skin contact, high wear comfort and skin compatibility are crucial for the quality of the product and customer satisfaction. Manufacturers should therefore avoid chemicals such as IBOA and connect plastics with processes that do not require adhesives, solvents or environmentally harmful substances - ultrasonics make this possible.
The switch from PVC to thermoplastic elastomers (TPE) in medical technology promotes health and environmental protection. TPE is phthalate-free, biocompatible and easier to recycle, which reduces the risks of allergies and environmental pollution. Despite challenges in joining TPE, ultrasonic welding offers an effective solution for stable and durable joints. This step improves product quality and minimizes health risks in the medical industry.
Minimal scrap rates with twice as fast cycle times: New developments in ultrasonic welding enable an optimization of production and can permanently reduce manufacturing costs for batteries and wire harnesses. A big help comes from the experience gained in the welding of plastics.

Up to 150 data points per welding process: Ultrasonic welding offers exciting opportunities for the digitalization of battery production - both in manual workstations and automated systems. If the data is used correctly, both safety and efficiency can be permanently increased, and new standards can be set in quality control.
Joining medical applications quickly and sustainably with ultrasonics
Connecting plastics without adhesives: Using ultrasonics as a joining technology, companies can produce their applications skin-friendly and eco-friendly. If certain specifications for the components are met, the process can also be used for sensitive applications with complex geometries.
Using data to achieve the perfect packaging process
Data is also the new oil in the packaging industry: it helps to make the process even safer, even more efficient and even faster. We show how companies can digitize their packaging process with ultrasonics to gain a competitive advantage.
Despite increasing cost pressure, many companies have accepted the high reject rates in the packaging of food and animal feed. Yet the most common reason for rejects in packaging machines can be easily avoided - with ultrasonic sealing technology.
Enhance the reliability of sealing sustainable materials
The latest generation of Herrmann Ultraschall's longitudinal seal module (LSM) ensures reliable longitudinal seals for applications like pillow bags, even with the narrowest of process windows. Regardless of variations in the speed of flow wrappers or other packaging machines, the LSM ensures seals with a visually flawless appearance.
Sustainable packaging materials are crucial to meeting the demands of the PPWR, but processing them using conventional methods is anything but easy. With ultrasonics, it is possible to seal the challenging materials safely - thanks to cold welding tools and precise controller.
