the application of hot melt adhesive

Diapers are an important part of modern infant and adult care products. The application of hot melt adhesive plays a vital role in their design and manufacturing process. The core function of diapers is to quickly absorb and lock urine, keep the wearer dry and comfortable, and prevent leakage. All of this is inseparable from the effective bonding of hot melt adhesive. The application of hot melt adhesive in diapers is mainly reflected in several key parts: elastic waistband, legcuff, bonding of absorbent core with topsheet and backsheet, etc. The main reason for using hot melt adhesive is its excellent bonding performance and instant curing characteristics. Compared with traditional glue, hot melt adhesive does not contain solvents, is non-toxic and environmentally friendly, and can be quickly cooled and cured in a short time, which not only improves production efficiency, but also reduces energy consumption and pollution in the production process. In addition, diapers adhesive has good elasticity and flexibility, and can stretch freely with the wearer's activities, ensuring that diapers can maintain a tight fit in different postures and effectively prevent urine leakage. For infants and young children, this fit is particularly important because it is directly related to the comfort and leak-proof effect of diapers, reducing the frequency of replacement, and allowing babies to enjoy longer dryness and comfort. More importantly, the formula of hot melt adhesive can be adjusted according to the different needs of diapers, such as improving water resistance, enhancing elastic recovery or optimizing breathability, so as to meet the special needs of specific user groups, such as infants with sensitive skin or adult users who need to wear them for a long time. In summary, hot melt adhesive has become an indispensable key material in diaper manufacturing with its high efficiency, environmental protection and flexibility, and has made important contributions to improving the overall performance and user experience of diapers.
