What Is Hot Melt Adhesive?

1. Overview of hot melt adhesive,elastic adhesive

Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with the change of temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product. Because the product itself is solid, it is easy to package, transport, store, solvent-free, pollution-free, non-toxic; as well as simple production process, high added value, high bonding strength, fast speed and other advantages.

2. Do diapers contain "hot melt adhesive"?

The production process of diapers is a complex combination process, which is composed of surface non-woven fabrics, absorbent cores, PE composite bottom film, Velcro buttons and front waist tapes, anti-side leakage non-woven fabrics, elastic bands and many other materials. The combination of the above materials is bonded by hot melt adhesive, which is the current production process of all diapers. It can be seen that there will be "hot melt adhesive" in the production process of normal diapers.

3. What is the "drop glue" in diapers?

How is the glue formed? In the process of using hot melt adhesive, we need to use the glue machine equipment. There are two ways of gluing, one is spraying glue, the other is scraping glue, these two ways use the spray gun Compared with the scraping gun, the spray gun uses several small holes of the spiral to blow out the gas at a set air pressure, and then sprays the glue squeezed out of the glue hole in the middle of the air hole into a spiral shape and sprays it on the surface of the material to be compounded. Then it goes through a series of pressing rollers to firmly bond the material together. And some brands of diapers often complain to customers that there are some yellow glue-like substances on the back or surface of the product, which is called glue in the industry.

4. Is "drop glue" harmful to the body?

Will the glue drop cause harm to the human body? From the first point above, it can be seen that hot melt adhesive is non-toxic and tasteless, and is an environmentally friendly chemical product, and its physical state changes with the change of temperature. Therefore, the hot melt adhesive is used in the production of diapers, and the formed glue is a production defect and belongs to the after-sales scope of the product, but it will not cause any harm to the human body.
