It is a thermoplastic, solvent-free adhesive that is applied in a molten state and forms a bond upon cooling. This "invisible" material is responsible for holding the complex, multi-layered structure of a diaper together, directly impacting its integrity, performance, and comfort.Without advanced adhesive systems, modern, high-performance diapers as we know them would not be possible. 1. Core Functions and Application AreasHMA is used in nearly every part of the diaper assembly: Application AreaSpecific FunctionConstruction / LaminationBonding the layers together: the Top Sheet (non-woven), Absorbent Core (fluff & SAP), and Back Sheet (PE film).Elastic AttachmentSecuring the leg elastics and waist elastics to the non-woven materials, creating the crucial leak-guard cuffs.Core Stabilization"Locking" the fluff pulp and Super Absorbent Polymer (SAP) in place within the core to prevent shifting and clumping (Anti-Bunching).Fastening SystemUsed in the assembly of hook-and-loop tabs (e.g., Velcro?-style closures) and adhesive tapes.Standing Leg CuffsProviding the initial "pop-up" structure for inner leg barriers.2. Key Properties of an Ideal Diaper GlueTo perform in such a demanding product, diaper adhesives must possess a unique set of properties:High-Tack & Fast Setting: Must grab quickly on high-speed production lines (often exceeding 500 diapers/minute).Strong Adhesion: Create a durable bond between dissimilar materials (e.g., polyolefin film and non-woven fabric).Softness & Flexibility: The adhesive line must remain flexible and not become brittle, ensuring the diaper is soft and moves comfortably with the baby.Resistance to Water & Body Fluids: Bonds must not break down when exposed to urine or moisture.Breathability (for specific types): Some HMAs are formulated to be micro-porous, allowing for the construction of breathable laminates.Safety & Compliance: Must be non-toxic, hypoallergenic, and free from harmful substances (compliance with EU Toy Safety, FDA, REACH, etc. is mandatory).3. Types of Hot Melt Adhesives UsedThe base polymer defines the adhesive's characteristics: TypeProsConsCommon UsesSBS (Styrene-Butadiene-Styrene)Cost-effective, high tack, good adhesion.Lower resistance to heat and oxidation (can yellow). Can be too stiff.Core stabilization, some lamination.SIS (Styrene-Isoprene-Styrene)Softer, more flexible, excellent tack. Good low-temperature performance.Moderate heat resistance.Elastic attachment, ideal for leg cuffs where softness is critical.APAO (Amorphous Poly-Alpha-Olefin)Excellent heat & aging resistance, good water resistance, very clean (colorless).Higher cost, lower tack.Lamination of backsheet and topsheet, where a clean appearance and durability are key.Most commercial diaper adhesives are blended formulations, combining these polymers with:Tackifiers: To increase stickiness.Plasticizers/Oils: To adjust viscosity and flexibility.Antioxidants: To prevent thermal degradation.4. Industry Trends & InnovationsOdor Control: Development of low-odor and odor-neutralizing adhesives for a "cleaner" feel.Plant-Based & Renewable Materials: Exploration of bio-based tackifiers and polymers to improve sustainability.Application Technology: Advanced, non-contact spray systems (e.g., spiral spray) that use less adhesive while providing better coverage and softer hand-feel.PACKING&SHIPPING
