Is the hot melt adhesive added to diapers toxic?
Dec 31, 2024
Hot melt adhesives are a type of plastic adhesive whose physical state changes with temperature, but whose chemical properties remain unchanged. They are non-toxic, odorless, environmentally friendly and have high added value. Because they are easy to pack, transport, store, and are pollution-free, and have high bonding strength and fast speed, they are widely used as diaper adhesives to bond the materials between the diaper's edges and layers.
The production process of diapers is complex and is composed of a variety of materials, which are bonded by hot melt adhesives. Sometimes mothers will find yellow colloids on the back or surface of diapers, which is called dripping glue. Glue dripping is formed when the pores are blocked when applying glue with a spray gun or a scraper. Although large factories use advanced detection systems, glue dripping cannot be completely avoided. However, glue dripping is only a production defect and will not cause harm to the human body. Mothers can use diapers containing hot melt adhesives with confidence.
The smell of hot melt adhesives comes from the inherent smell of its raw materials such as resins and tackifiers. New smells may be generated due to the influence of production and circulation links, but they are generally mild and non-toxic. In the production of diapers, the glue dripping caused by hot melt adhesives is a production defect, which is harmless to the human body and belongs to the scope of product after-sales. Therefore, mothers do not need to worry too much about the smell or glue dripping of diapers containing hot melt adhesives.
