Kae Hwa’s HygieSoft™ Sanitary Films provide ultra-thin, noise-free protection, ideal for sanitary napkins and panty liners. Offering superior fluid resistance, dynamic breathability, and skin-friendly softness, it is designed to meet the highest feminine hygiene standards and ensure maximum comfort and discretion for everyday wear.
For feminine hygiene products, the backsheet does more than prevent liquid from passing through. As sanitary pads become thinner and more comfort-focused, backsheet materials are increasingly expected to deliver a combination of low noise, breathability, softness, and dependable liquid barrier performance.
For hygiene brands and product developers, material stiffness and surface friction can affect how a sanitary pad feels and sounds during movement. At the same time, limited moisture-vapor transmission may contribute to heat and humidity buildup during extended wear.
HygieSoft™, developed by Kae Hwa Industrial Co., Ltd., is a breathable film and laminate platform designed for sanitary napkins, panty liners, and other personal hygiene applications. By combining precision cast-film technology, controlled microporous structures, and nonwoven lamination, HygieSoft™ helps manufacturers balance discreet wear, breathable comfort, softness, and backsheet protection within a lightweight material system.
For ultra-thin sanitary products, backsheet noise can be an important part of the overall wearing experience.
HygieSoft™ is engineered with a flexible film structure, controlled polymer formulation, and customizable surface texture to help reduce noise caused by bending, folding, and friction during movement.
When combined with a suitable nonwoven substrate, the laminate can also provide a softer, less plastic-like feel than a conventional standalone film structure.
For premium sanitary napkins and panty liners, this combination of flexibility and lower material noise supports a more discreet and natural wearing experience.
HygieSoft™ uses a microporous film structure designed to allow moisture vapor to pass through while maintaining the liquid barrier required for hygiene backsheet applications.
This vapor-transfer capability helps manage heat and moisture accumulation within the product, supporting a drier and more comfortable environment during extended wear.
Breathability can be adjusted according to film basis weight, microporous structure, laminate configuration, and the performance requirements of the finished hygiene product.
This gives manufacturers greater flexibility when balancing moisture-vapor transmission, liquid resistance, softness, and converting performance.
HygieSoft™ breathable films are available in approximately 12–45 gsm, providing flexible options for lightweight and ultra-thin hygiene product designs.
Precision cast-film manufacturing helps maintain consistent film formation and surface quality while supporting the softness required for personal care applications.
When laminated with selected nonwoven materials, HygieSoft™ can create a flexible, cloth-like composite structure that improves both tactile quality and product aesthetics.
Key design advantages include:
For brands developing thinner and more comfortable feminine care products, backsheet weight and flexibility can play an important role in achieving the desired product positioning.
Breathable backsheets must manage moisture vapor without compromising their primary role as a liquid barrier.
HygieSoft™ uses a controlled microporous structure to provide moisture-vapor transmission while resisting liquid penetration under the intended product conditions.
Film basis weight, structure, and related performance parameters can be customized according to the requirements of the finished sanitary product.
As part of a sanitary napkin construction, HygieSoft™ provides a dependable backsheet layer that helps reduce the risk of liquid passing through the back of the product while maintaining lightweight, breathable, and flexible characteristics.
Final leak protection, however, depends on the complete product design, including the absorbent core, acquisition and distribution layers, dimensions, edge construction, and overall backsheet configuration.
HygieSoft™ films and laminates can be tailored to different personal hygiene product structures and performance requirements.
For day and night sanitary pads where low material weight, softness, breathability, and reliable backsheet protection are key design priorities.
Suitable for lightweight daily liners requiring a thin, flexible, and breathable backsheet with minimal material bulk.
Designed for care products where soft-touch materials, moisture management, and dependable liquid resistance are important for extended-use comfort.
HygieSoft™ can be incorporated into product constructions using cotton or organic-cotton topsheets, giving manufacturers greater flexibility when developing premium sanitary products focused on softness and natural-touch positioning.
Suitable for breathable backsheet constructions that require a balance of softness, liquid resistance, lightweight performance, and wearing discretion.
A high-performance sanitary napkin backsheet is not defined by a single property.
Softness, noise level, breathability, barrier performance, and processability are influenced by the interaction between polymer formulation, film basis weight, microporous structure, surface texture, and lamination design.
HygieSoft™ combines Kae Hwa Industrial's film manufacturing and lamination capabilities to control these variables from film formation through final composite development.
Controlled cast-film processing supports consistent film formation, basis weight, surface quality, and mechanical behavior across production runs.
Stable film quality is particularly important for hygiene manufacturers that require consistent downstream lamination and converting performance.
The microporous structure is engineered to balance moisture-vapor transmission with resistance to liquid penetration.
This enables manufacturers to incorporate breathability into the backsheet without moving away from its essential barrier function.
Surface patterns and embossing can be customized to modify tactile feel, appearance, friction characteristics, and overall product aesthetics.
This gives hygiene brands additional flexibility when developing differentiated backsheet designs.
Different nonwoven structures and basis weights can be combined with HygieSoft™ films to adjust softness, strength, cloth-like feel, and converting behavior.
Kae Hwa Industrial also offers solvent-free lamination capability, allowing the bonding system to be selected according to the product structure and processing requirements.
Where appropriate, solvent-free lamination can help reduce VOC emissions associated with conventional solvent-based manufacturing while maintaining stable composite performance.
Many of the material characteristics that define comfort are not immediately visible in the finished sanitary product.
How quietly the backsheet moves, how flexible it feels, how effectively moisture vapor can escape, and how consistently the material resists liquid penetration can all influence the performance and perceived quality of the final product.
HygieSoft™ is developed around four key backsheet requirements:
Softness. Low noise. Breathability. Reliable liquid protection.
By addressing these requirements at the material level, hygiene manufacturers can develop sanitary napkins and liners that are lighter, more comfortable, and better aligned with premium product positioning.
Kae Hwa Industrial provides customizable HygieSoft™ solutions based on film basis weight, breathability, surface texture, color, nonwoven selection, and lamination configuration, helping brands and converters develop sanitary napkin backsheets for specific product and market requirements.

The pores in our HygieSoft™ membrane are engineered to be significantly smaller than a liquid droplet, yet larger than a water vapor molecule. This physical structure guarantees that menstrual fluid is completely locked in, while humid air is allowed to vent out continuously.
Yes. Odor in hygiene products is often exacerbated by trapped heat and bacterial growth in damp environments. By allowing the pad to "breathe," our film keeps the internal micro-climate dry and cool, which naturally suppresses bacterial proliferation and associated odors.
Absolutely. We strictly utilize an advanced solvent-free lamination process. This means there are no harsh chemical adhesives or volatile organic compounds (VOCs) that could cause allergic reactions or skin sensitization in delicate areas.
