| Abstract:This study investigated the influence of filter rod substrate properties on the bonding performance of centerline adhesives. Three types of plug wrapping papers， standard， high-porosity， and barrier， were combined with four adhesive formulations (CLC-YN-102， CLC-YN-102G， CLC-YN-102GQ， and H.B Fuller) and three application patterns (“Single-line”， “S”， and “Dot”) to systematically analyze their interactive effects. The results showed that the “Single-line” pattern yields the highest bonding strength due to its continuous and uniform adhesive distribution， achieving a peel force approximately 30% higher than the “Dot” pattern. The bonding strength increased with paper porosity； high-porosity paper， with a loose fiber structure and high surface free energy (75.4 mJ/m²)， enhanced adhesive penetration and interfacial bonding， exhibiting a 20% improvement over barrier paper. In contrast， barrier paper showed poor wettability (water contact angle of 120.3°) and the lowest adhesion. Among the adhesives， H.B Fuller demonstrates superior performance， combining low shear viscosity with moderate surface free energy (62.79 mJ/m²)， resulting in excellent bonding stability and higher peeling force. |
