摘要:
The invention relates to a hot-melt adhesive substance for sticking together fibrous materials such as matted nonwovens or woven textiles with smooth substrate surfaces, such as plastic or metal films, and for laminating said materials. Said substance is characterised in that it contains at least one polyolefin which has been produced by polymerisation in the presence of metallocene as a catalyst and has a ring/ball softening point of between 50 and 165°C and a melting viscosity, measured at a temperature of 170°C, of between 20 and 40,000 mPa-s. The hot-melt adhesive substance can also contain at least one adhesive component and is used in a quantity of between 3 and 6 g/m2, preferably between 4 and 5.5 g/m2, for sticking a film to a nonwoven material during the production of hygiene items such as disposable nappies, baby nappies, incontinence products, panty liners and/or sanitary towels.
