Why do diapers use hot melt adhesive?

The production process of diapers is a relatively complex combination process, which is composed of many materials such as surface non-woven fabric, water-absorbing core, PE composite bottom film, magic buckle and front waist sticker, anti-leakage non-woven fabric, elastic band, etc., and the combination of the above materials is bonded by hot melt adhesive. This is the current production process of all diapers. It can be seen that the normal production process of diapers will have the existence of “hot melt adhesive”.

What are the gluing methods for diapers?

There are two gluing methods, one is spraying glue and the other is scraping glue. These two methods use spray guns and scraping guns. The spray gun uses several small holes in the spiral to blow out the gas at a set air pressure, and then the glue squeezed out of the glue outlet hole in the middle of the air hole is sprayed into a spiral shape on the surface of the material to be compounded, and then passes through a series of pressing rollers to firmly compound the materials together.

Is the smell of hot melt adhesive toxic?

The raw materials of hot melt adhesive are composed of main resin, tackifier resin, diluent or softening oil, filler and other ingredients. The inherent smell of the raw materials is an important source of the smell of hot melt adhesive. For example, most EVA has a faint acetic acid smell, and synthetic rubber also has its own smell, but the concentration is different. The rosin-type tackifier resin in the tackifier resin has the smell of rosin, and C9C5 resin has their own different smells. Even the fully hydrogenated resin has its own smell, but our sense of smell may not be able to detect it. Other raw materials also have odors, but the concentration is different and the intensity is different.

During the production process, hot melt adhesive may also have new odor sources. Through production process control, the purpose of reducing odor can be achieved. During the logistics and transportation of hot melt adhesive, new odors may also be introduced. But in general, the slight odor contained in hot melt adhesive itself is non-toxic.

Is hot melt adhesive harmful to babies?

Hot melt adhesive is non-toxic and odorless, and is an environmentally friendly chemical product. Its physical state changes with temperature. Therefore, when hot melt adhesive is used in the production of diapers, the glue dripping formed is a production defect and falls within the scope of product after-sales, but it will not cause any harm to the human body. So it can be used with confidence.
