Baby diaper frontal tapes are crucial raw materials, typically made from laminated Polypropylene (PP) film or nonwoven fabric, forming a soft, strong "landing zone" for the side tapes, allowing for multiple adjustments without tearing the diaper's backsheet, and often featuring printed designs for aesthetics and brand recognition. Key components include durable PP film, sometimes combined with BOPP, nonwoven layers, and specialized adhesives for secure fastening, with options for textile-based knitted loops for a cloth-like feel.
