They primarily serve the following functions:
Absorb urine, bodily fluids, wound exudate, and spilled liquids
Prevent moisture from damaging mattresses, sofas, and furniture
Reduce skin irritation, infections, and pressure ulcers caused by dampness
Maintain hygiene and cleanliness for patients, the elderly, infants, and pet owners
Unlike reusable pads, disposable underpads are discarded after a single use, which reduces cleaning work and lowers the risk of cross-contamination.
3. Key Features of High-Quality Disposable Underpads
The performance of disposable underpads depends on several core features. Below are the most important characteristics that define a reliable product.
3.1 High Absorbency
Absorbency is the most critical function. High-quality underpads use a composite absorbent core that quickly draws in liquid and locks it inside to prevent reverse leakage.
3.2 Waterproof & Anti-Leak Backing
The bottom layer uses waterproof materials to stop liquids from penetrating through, effectively protecting mattresses and furniture.
3.3 Soft & Skin-Friendly Surface
The top layer directly touches the skin, so it must be gentle, non-woven, breathable, and free of irritating chemicals.
3.4 Good Breathability
Breathable structure reduces stuffiness and helps keep skin dry, lowering the risk of rashes and discomfort.
3.5 Strong & Tear-Resistant Structure
A stable layered design ensures the pad does not break, clump, or deform after absorbing liquid.
3.6 Quick Liquid Penetration
A good surface layer allows liquid to pass through rapidly, keeping the user's skin dry at all times.
4. Common Types & Classifications of Disposable Underpads
Disposable underpads can be classified in multiple ways to meet different usage needs.
By Absorbency Level
Light absorbency: For daily light incontinence, pet pads, small liquid spills
Medium absorbency: For daytime elderly care, baby use, general medical care
Heavy absorbency: For overnight use, moderate-to-heavy incontinence, hospital wards
Ultra-heavy absorbency: For critical care, large-area exudate, operating rooms
By Usage Scenario
Medical grade: High sanitation standards, suitable for hospitals and clinics
Home care grade: Soft and comfortable, designed for family daily use
Pet-specific: Economical and thin, ideal for puppy training and pet beds
Travel & portable: Individually wrapped, lightweight for outdoor and travel use
By Structure & Design
Standard flat underpads: The most common type, simple and widely applicable

6. Main Materials Used in Disposable Underpads
Disposable underpads consist of multiple functional layers, each made of specialized materials.
6.1 Top Surface Layer
The surface layer is usually made of hydrophilic nonwoven fabric (polypropylene fiber). It is soft, breathable, and allows liquid to pass through quickly while keeping the surface dry.
6.2 Absorbent Core Layer
The core is the most important functional part, typically composed of:
Fluff pulp: Quickly absorbs and distributes liquid evenly
Super Absorbent Polymer (SAP): Absorbs 30--100 times its weight and locks liquid in gel form to prevent leakage
6.3 Backing Layer
The backing is generally made of PE waterproof film or breathable PE film, providing reliable leak-proof protection.
6.4 Adhesive & Structural Layers
Eco-friendly hot-melt adhesives are used to bond layers together, ensuring stability during use.
