Hot Melt adhesives can be found in almost all products and areas of our lives thanks to the great advantages that their use offers. In the case of the manufacturing of disposable nappies, this type of adhesive is used throughout the production process of this material.

Children and babies carry out all of their activities wearing a nappy: running around, crawling, sleeping. Therefore, it is necessary to create a product that precisely adapts to each movement in order to keep the baby dry and comfortable.

When it comes to manufacturing a product like a disposable nappy we look for an adhesive that has very specific characteristics. Hot melt adhesives and glues bring together all these desired properties.

When it comes to manufacturing a sanitary product or one that is contact with children and babies, it is very important that it is a secure product, that it is non-toxic and that it does not produce unpleasant olours.

The application of hot melt adhesives is present in almost all the pieces that comprise the nappy as it is used to glue all the parts such as the pad (absorbent body) and the elastics.

The outer part of the nappy is normally covered with a polyethylene film in order to prevent the liquid from escaping. Normally, this layer is stuck down with a heat melt adhesive and using a lamination process on another layer that gives the fabric a more agreeable appearance.

The side tape is one of the key components of nappies that is also made using our products. This part is so important because it is used to fit the nappy and adjust it to the baby’s waist.

Lastly, the front tape is also stuck to the body with Hot Melt glue and is used to allow multiple reapplications of the side tapes to the nappy, without the possibility of the plastic film tearing.

In conclusion, the particular characteristics that a specialised adhesive for nappies needs to have are as follows:

It needs to have a strong grip in order not to compromise the integrity of the product. It must be an adhesive with great elasticity in order to ensure that the nappy maintains its shape and meets the challenge of keeping the baby dry when it is active and when it is sleeping. Lastly, it has to guarantee a bending and precise return system in order to prevent leaks.
