Disposable Incontinence Underpad Leak-Proof Barrier Hot Melt PSA Adhesive
This hot‑melt PSA adhesive is specially developed for disposable incontinence underpads. It provides reliable leak‑proof performance when applied in barrier cuff edge sealing processes. Forming stable and flexible bonds, it effectively seals edge flaps to avoid liquid penetration and side leakage. It exhibits excellent adhesion to non‑woven fabrics and PE backsheet, and is suitable for high‑speed production lines of disposable hygiene articles
