Wound care dressing frames fix functional dressings, requiring soft fit, firm bonding and biocompatibility, adapting to wound surface changes, no irritation to damaged skin. Traditional adhesive bonding has poor fit, easy warping, while mechanical processing has low efficiency. DaokeDao laser welding realizes firm connection between dressing frames and functional layers, suitable for medical-grade non-woven fabrics and soft PP materials, with flexible and tough welds, fitting the skin gently, no irritation to wound tissues. The welding process is fast and clean, no chemical residues, complying with medical wound care product safety standards. The weld has good air permeability, ensuring wound ventilation and accelerating healing. The equipment supports continuous roll-to-roll welding, adapting to large-scale production of disposable wound care supplies, reducing production costs, helping medical care manufacturers improve product quality and patient comfort.
