ANDRITZ adult incontinence technology: Shaping the future of hygiene converting

ANDRITZ hygiene converting solutions are redefining what is technically and economically possible. With decades of engineering excellence behind them, These technologies address the complex interaction between absorbent performance, wearer comfort, production efficiency, and environmental responsibility.

A fully integrated approach – from raw materials to finished products

ANDRITZ offers a comprehensive technology portfolio covering the entire absorbent hygiene products value chain – from fiber preparation and nonwoven production to advanced converting solutions for adult diapers, pant diapers, and underpads.

The integration of Diatec technology into the ANDRITZ family has further strengthened this expertise, creating a seamless technological bridge from raw material roll goods such as spunlace, airlaid, and spunbond to the finished hygiene product.

For manufacturers, this means access to a broader knowledge base and a deeper understanding of individual production processes. Expertise is not limited to converting specialists alone; customers benefit from support by ANDRITZ experts across related technology areas. The result is shorter planning phases, higher‑quality consulting, and reliable support throughout the entire product lifecycle.

Advanced core formation and ultrasonic bonding – a dual performance driver

A key strength of ANDRITZ adult incontinence technology lies in its advanced absorbent core systems. Modern adult products must combine high fluid retention with a thin, flexible, and discreet design. ANDRITZ forming systems are engineered for high superabsorbent polymer (SAP) concentrations, improving absorbency and product reliability even under demanding usage conditions.

These systems are complemented by sophisticated turning and placing technology, ensuring excellent process stability and consistently high product quality – even at elevated production speeds.

Another decisive innovation is ANDRITZ’s expertise in ultrasonic bonding, particularly for side‑seam sealing in adult pants. Traditionally, achieving strong and reliable seams at high speed has been a major challenge. ANDRITZ ultrasonic solutions overcome this limitation by delivering exceptional seam integrity, system reliability, and wearer comfort without compromising productivity. Fast and simple size changes further enhance line flexibility, making ultrasonic sealing one of the most valued features in modern adult hygiene converting.

Bonding reinvented: ANDRITZ neXbond ultrasonic

The ANDRITZ neXbond ultrasonic process represents a major breakthrough in the production of elastic waistbands for baby and adult hygiene products. Instead of using hot‑melt adhesives, the technology relies on high‑frequency ultrasonic energy to create a fully glueless, soft, and durable bond.

Tensioned elastic strands are securely entrapped between two layers of nonwoven fabric and locked in place as the elastics return to their natural diameter. This results in excellent elasticity, high skin‑friendliness, and superior wearer comfort.

The ultrasonic process is instantaneous and highly precise, eliminating typical adhesive‑related issues such as creep, stiff bonding zones, or thermal material damage. At the same time, it supports continuous, closed‑loop production at speeds of up to 400 m/min, ensuring high productivity and consistent quality.

Beyond performance benefits, neXbond also contributes to sustainability. By eliminating adhesives entirely, the process is cleaner, chemical‑free, and energy‑efficient, reducing downtime and operating costs. Glueless products are also easier to recycle, supporting circularity targets across the hygiene industry.

Designed for efficiency, ergonomics, and global market readiness

ANDRITZ converting platforms are engineered with a strong focus on operator ergonomics, intuitive operation, and simplified maintenance. Fast, interruption‑free size changes, customizable layouts, and user‑friendly interfaces reduce training requirements and downtime, contributing to stable, high‑performance production environments.

Driven by demographic developments in Europe, North America, and Japan, adult incontinence remains one of the fastest‑growing segments in absorbent hygiene. ANDRITZ high‑automation converting solutions enable manufacturers to respond to this growth with consistent quality, high output, and long‑term process reliability.

Sustainability as a core element of ANDRITZ hygiene converting

Sustainability is a central pillar of ANDRITZ’s hygiene technology strategy. Upstream nonwoven technologies enable the use of cellulosic and natural fibers, reducing reliance on plastics and supporting biodegradable or bio‑based product concepts.

ANDRITZ spunlace processes allow bio-based fiber blends to be used in high‑performance hygiene components such as topsheets and acquisition layers. Integrated into adult incontinence products, these materials help reduce the overall environmental footprint while maintaining softness, absorbency, and durability.

At the converting stage, low waste levels – typically between one and three percent – combined with high line speeds result in significant material savings over the lifetime of a production line. Continuous development efforts to reduce or eliminate plastic components further support industry‑wide sustainability and circularity goals.

By combining high‑speed efficiency, responsible material concepts, and advanced process technology, ANDRITZ enables hygiene manufacturers to meet regulatory requirements, customer expectations, and sustainability commitments – without compromising product quality or performance.
