elastic adhesives

The adhesives used in disposable sanitary products are mainly hot melt adhesives based on thermoplastic polymers. This material is applied in a molten state, can wet the adherend, and can achieve rapid bonding by applying light pressure after cooling and hardening. Its main types cover a variety of special adhesives, as follows:   1.Position adhesives are mainly used for the back layer of sanitary napkins. It can firmly stick the sanitary napkin to the underwear and effectively prevent movement. The adhesive has moderate cotton cloth peeling force and excellent anti-transfer performance. It has strong adaptability to seasons and regions and can maintain initial adhesion even in low temperature environments. In addition, it has light color, low odor, is not sensitive to ultraviolet light, is safe and non-toxic to use, and is not easy to cause allergies. 2.Construction adhesives are specially used for bonding non-woven fabrics, perforated films and PE back films, as well as absorbent paper and non-woven fabrics, PE or fluff pulp and other materials. At the same time, it can also effectively bond elastic waistbands and PE back films. Structural adhesives have good thermal stability and suitable open time, and have excellent bonding effect on PE film and non-woven fabrics, no reverse osmosis, no scalding of PE film, and excellent performance on the machine. 3.Elastic adhesives are mainly used to fix elastic materials, so that they can be better bonded to non-woven fabrics and base films, thereby enhancing the close-fitting comfort and leak-proof performance of the product. Elastic adhesives have high creep resistance, good thermal stability and suitable open time, and have good bonding effect on elastic materials and PE backing materials or non-woven fabrics, no reverse osmosis, and are soft and elastic. 4.Wetness indicator adhesives are a kind of hot melt pressure-sensitive adhesive containing PH color developer, which will change color when wetted with urine, playing a prompting role. During use, the glue temperature and parking time of urine indicator adhesive in the glue machine must be strictly controlled to prevent excessive aging and loss of urine indicator function.   These hot melt glues have been widely used in disposable sanitary products such as sanitary napkins, diapers and other products, ensuring that the products have good bonding performance and user experience during use.

In the diaper manufacturing industry, elastic adhesives is widely used as a key adhesive material. This is not only because of its good physical properties, but also because it can bring excellent comfort and fit to diapers. Elastic glues used in diaper is known for its high elasticity and recovery, which allows diapers to expand and contract freely with the body movements when the baby is moving. Whether crawling, standing or walking, elastic glues can ensure that the diaper remains tightly fitted, effectively preventing urine from leaking sideways, thereby ensuring the sealing performance of the diaper. In addition, the softness and skin-friendliness of elastic adhesives are also important reasons for its popularity. It does not cause pressure or friction on the baby's delicate skin, reducing the risk of red buttocks and allergies. At the same time, elastic adhesives also has a certain breathability, which helps to keep the air circulation inside the diaper, so that the baby can also feel dry and comfortable when wearing the diaper. In the production process of diapers, the application of elastic adhesives requires precise calculations and rigorous testing. Manufacturers will ensure that the elasticity, softness and breathability of the elastic are optimally balanced, so as to produce diaper products that are in line with the baby's physiological characteristics and provide an excellent wearing experience. In summary, the reason why elastics are widely used in diapers is that they can bring excellent elasticity and comfort to diapers, ensuring that babies can stay dry and comfortable during any activity. With the advancement of technology, the performance of elastics will be further improved, bringing more innovations and breakthroughs to the diaper manufacturing industry.
