100% Biodegradable Bamboo Fiber & Eco Baby Diapers
Shenghongda's eco-conscious hygiene division engineers 100% certified biodegradable bamboo fiber baby diapers for premium sustainability brands in Europe, North America, Australia, and New Zealand. Designed to replace fossil fuel-derived plastics, our eco diapers utilize non-woven topsheets and backsheets spun from 100% naturally antibacterial, hypoallergenic bamboo viscose fiber. The absorbent core incorporates Totally Chlorine-Free (TCF) North American Weyerhaeuser virgin wood pulp certified under FSC-C152349 Chain of Custody, reinforced with bio-based superabsorbent polymers. The waterproof barrier replaces traditional polyethylene with a breathable, 100% compostable Polylactic Acid (PLA) and cornstarch-derived bio-film. Under OECD 301B industrial composting laboratory standards, over 68% of the diaper mass biodegrades within 90 days (reaching up to 85% within 180 days), compared to over 400 years for conventional plastic diapers. Completely free from elemental chlorine, phthalates, parabens, perfumes, and heavy metals. MOQ is 100,000 pieces with FOB pricing from $0.05 to $0.10 per unit and 340,000 units per 40HQ container.
