Configurable film-free nonwoven outercover platform for disposable hygiene products

Overview

This offering presents a configurable film-free nonwoven outercover platform designed to replace the continuous polyethylene (PE) film used in conventional disposable hygiene products. Rather than a single material, the platform comprises five candidate material routes that can be selected and optimized for specific product categories, including panty liners, sanitary pads, and period pants. The core value proposition is the replacement of dense PE film with engineered fibrous networks that provide liquid resistance while maintaining interconnected pathways for air and water-vapor transport. This directly addresses common drawbacks of film-based outercovers, such as rustling and crackling noise, while improving breathability and comfort.

Technical specifications

Key features:

• Five configurable material routes allow tailoring to different product requirements and performance targets.
• Fibrous networks are engineered through fiber selection, web-structure design, multilayer construction, bonding, and optional surface treatments.
• Multilayer fine-fiber networks create tortuous pathways that resist liquid penetration while retaining open pores for air and vapor transport.
• Manufacturing processes include SMS (spunbond-meltblown-spunbond), spunlace, and through-air bonding, providing a practical, industrial-scale foundation.
• The platform is designed to balance loftiness and softness, with stiffness identified as a key optimization focus.
• Development is structured in five phases over approximately 6 to 24 months, from route screening and lab prototyping to pilot-scale validation and industrial qualification.

Technology readiness level

This platform is at an early development stage, with the research hypothesis and material routes proposed for validation. The proposed stage-gated program includes laboratory prototyping, optimization against reference products, pilot-scale roll production, and final safety and compatibility testing. The technology is not yet commercially deployed and requires collaborative development to reach industrial readiness.
