Elastic adhesive serves as a core bonding agent in sanitary pads-particularly in high-end or 3D-barrier models-used to secure elastic components. Its primary function is to ensure the elastic elements remain firmly in place, thereby enhancing the product's body-hugging fit and leak-proof performance.
Preventing Elastic Displacement or Retraction
Elastic adhesives must possess high creep resistance and thermal stability to maintain the position of the elastic material throughout the stages of production, storage, and usage, thereby preventing protective failure caused by loosening.
Supporting Dynamic Leak-Proof Structures
In sanitary pads featuring elastic waistbands or leg-cuff leak-guard designs, the elastic components-secured by the adhesive-can expand and contract in response to movement, thereby enabling "dynamic leak protection." This feature proves particularly effective during activities such as turning over or walking.
Enhanced Close-Fitting Comfort
Through the precise bonding of elastic materials, the sanitary pad naturally flexes and extends to follow the body's contours, minimizing friction and pressure while enhancing wearing comfort during activities such as exercise or prolonged sitting.
Securing Elastic Leg Cuffs
The elastic adhesive is used to firmly bond elastic strands to hydrophobic non-woven fabric, enabling the side cuffs to "stand up" and form a three-dimensional elastic barrier that effectively prevents menstrual fluid from leaking sideways.
