Whether the hot melt adhesive in the diaper is toxic to the baby

The production process of diapers is a complex combination process, by surface non-woven fabric, absorbent core, PE composite bottom film, magic buckle and front waist paste, anti-leakage non-woven fabric, rubber tendons and many other materials combination, and the combination of all the above materials through hot melt adhesive bonding, this is the current production process of all diapers. Some brands of diapers can be found with a yellow, gummy substance on the back or surface, known in the industry as dripping glue.

In the process of using hot melt adhesive, we need to use glue machine equipment, there are two ways of gluing, one is spray glue, the other is scraping glue, these two ways both use the spray gun and scraping gun. Spray gun is to use several holes in the spiral to play the gas with a set air pressure, glue out of the glue hole surrounded in the middle of the pore into a spiral spray on the surface of the composite material, the material is then firmly bonded together by a series of press rollers.

The formation of glue drops is due to the blockage of the spiral pores in the production process. After the glue is pressed out from the pipeline, it is not affected by the spiral gas and condenses into lumps of glue drops on the product within a certain time. This probability is actually very small, but because the color of glue just drops on the product is white, and can not form an effective color difference with the product surface, so now some large factories used in the advanced visual detection system of stains can not be 100% removed. Therefore, the current level of technology in the industry can not avoid the formation of drip glue.

The smell of hot melt adhesive comes from hot melt adhesive itself, is the essential characteristic of hot melt adhesive, affected by raw materials, production process and circulation link. The raw material of hot melt adhesive consists of main resin, sticky tree finger, diluent or softening oil, filler and other components. The inherent smell of raw materials is an important source of hot melt adhesive smell, and the slight smell contained in hot melt adhesive itself is non-toxic.

Hot melt adhesive is used in the production of diapers. The glue drops formed by hot melt adhesive belong to the production defect and the after-sales scope of the product, but it will not cause any harm to human body.

Newly produced diapers will have a "kerosene smell," which is the smell of the hot adhesive grade antibiotic used in the diaper manufacturing process, and the newer the diapers, the more likely they are to have this smell. These smells are harmless to the baby. Open the package and take out the diaper and leave it for a day or so. The smell will dissipate soon.
