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

Shenghongda is an ISO 13485:2016 and FDA registered manufacturer of hospital-grade disposable underpads (chux) engineered for operating tables, maternity beds, nursing home furniture, and home care beds. Constructed with a 5-layer laminate architecture, our underpads feature a hydrophilic nonwoven topsheet, a tissue transfer layer, a virgin fluff pulp and Sumitomo SAP core, a secondary structural tissue layer, and a slip-resistant waterproof polyethylene (PE) backing. The surface utilizes precision diamond embossing that channels voided fluid outward in four directions, preventing pooling and accelerating strike-through below 2.0 seconds. Peripheral four-sided thermal sealing guarantees zero side border leakage even under active patient movement. Available in standard dimensions (40x60cm, 60x60cm, 60x90cm, 80x90cm) as well as heavy-duty 80x150cm and 80x180cm sizes featuring tuckable lateral nonwoven wings for hospital mattress anchoring. Grammage ranges from 40g to 130g per pad with FOB pricing of $0.04 to $0.18 per unit and container loading from 120,000 to 220,000 pieces per 40HQ.
