Structural adhesives used in the production of sanitary pads are critical materials that ensure the stable bonding of the product's various layers; they are primarily applied to bond multi-layer composite structures, thereby guaranteeing the product's structural integrity and user comfort during use.
Fabric Structural Adhesive: Used to bond the non-woven topsheet to the absorbent core, ensuring a smooth, wrinkle-free surface.
Three-Piece Structural Adhesive: Connects the central body to the side wings, enhancing lateral leak-proof performance.
Distribution Layer Structural Adhesive: Secures the distribution layer to the topsheet, improving the efficiency of rapid liquid penetration.
Chip Structural Adhesive: Firmly bonds the absorbent "chip" to the main absorbent core, preventing displacement.
Backsheet Structural Adhesive: Bonds the absorbent core to the breathable PE backsheet, enabling the "breathable yet impermeable" function.
3D Leak Guard Adhesive: Used for the structural bonding and formation of the 3D side leak guards, effectively preventing lateral leakage.
As environmental awareness grows, a new type of product-biodegradable sanitary pads-has emerged in the market. Due to the environmental pollution caused by landfilling and incineration, an increasing number of consumers are choosing to use biodegradable sanitary pads. In these products, structural adhesives are primarily applied to the coating of the topsheet and absorbent layers. Characterized by high strength and high viscosity, these adhesives enhance the structural stability and durability of the biodegradable sanitary pad's surface and absorbent layers. Furthermore, during use, the structural adhesives in biodegradable sanitary pads are capable of withstanding external forces while simultaneously undergoing natural degradation, thereby reducing environmental pollution.
