Product Description
20-50 GSM ES Thermal Bonded Nonwoven Fabric Roll for Alkaline Battery Separator Paper & Industrial Lamination Substrate
Product Overview Manufactured from 100% virgin PE/PP bicomponent ES fibers via precision thermal calender bonding, our 20 – 50 GSM ES Nonwoven Fabric features a uniform fiber web, ultra-thin smooth surface, and superior thermal sealability. With a low-melting PE sheath and high-strength PP core, it bonds effortlessly with PE films or metal casings without chemical adhesives—making it an ideal substrate for alkaline battery separator paper, hygiene PE film lamination backsheets, and precision industrial composites.
Key Performance Advantages
Uniform Fiber Distribution & Zero Pinholes: Advanced carding and thermal calendering eliminate thin spots and pinholes, preventing internal short circuits in batteries and liquid leakage in hygiene backsheets.
Superior Electrolyte Absorption & Alkali Resistance (Battery Grade): Offers rapid alkaline electrolyte wicking, high liquid retention, and strong chemical resistance in KOH environments without fiber degradation.
Wide Thermal Sealing & Lamination Window: The low-melting PE outer sheath enables low-temperature thermal lamination with breathable/non-breathable PE films—achieving high peel strength without shrinking or burning the film.
Cloth-Like Softness & Low Lint: Imparts a soft, textile-like outer feel to composite backsheets while maintaining high tensile strength and lint-free cleanliness on high-speed converting lines.
Strict Thickness & GSM Tolerance: Precision calender gap control ensures consistent caliper and basis weight across the entire roll width.
Material Composition: 100% Virgin Bicomponent ES Fiber (PE/PP Sheath-Core)
Basis Weight (GSM): 20 – 50 GSM (Customizable per caliper and strength specs)
Technics: Thermal Calender Bonded (Smooth / Fine Embossing)
Roll Width: Customized precision slitting
Color: Pure White (Optical brightener-free)
Optional Treatments: Permanent hydrophilic treatment (for fast electrolyte wicking) or standard hydrophobic/lamination grade
Main Applications
Alkaline & Primary Battery Separators: Separator paper substrate for AA/AAA/C/D alkaline batteries, zinc-carbon batteries, and specialty button cells.
Hygiene Film Lamination Backsheets: Cloth-like outer lamination layer bonded with PE breathable/cast films for baby diapers, adult incontinence briefs, and sanitary napkins.
Medical & Protective Composites: Soft outer/inner lamination substrate for surgical drapes, medical gowns, and sterile barrier packaging.
Industrial Lamination & Filtration: Precision backing substrate for membranes, tapes, and specialty composite sheets.
