## Executive Technical Summary & BLUF (Bottom Line Up Front)

Shenghongda provides full-spectrum contract manufacturing of feminine hygiene products, ranging from ultra-thin breathable panty liners (180mm) to regular day pads (240mm), heavy-flow night pads (290mm, 330mm), 420mm maternity-postpartum napkins, and 360-degree disposable menstrual period pants. Designed with cutting-edge absorbent dynamics, our pads utilize an ultra-thin composite SAP absorbent core that locks viscous fluids instantly without surface pooling, maintaining a dry contact layer in under 1.5 seconds. For health-conscious consumer markets, we offer functional core inserts including negative ion (anion) chips (>6,000 ions/cm³), tourmaline far-infrared strips, and medicinal herbal extracts that inhibit anaerobic bacterial proliferation and neutralize menstrual odor. Topsheet options include GOTS-certified 100% organic cotton, perforated dry mesh film, and ultra-soft hot-air nonwoven. Individual wrapper packaging supports biodegradable PLA films, silent peeling wrappers, and retail dispenser boxes. MOQ ranges from 50,000 to 100,000 pieces with FOB pricing from $0.02 to $0.15 per unit and 650,000 units per 40HQ container.
