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 characterized in that it contains at least one polyolefin which has been produced by polymerization 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.
A hot melt adhesive for adhesively bonding fibrous materials to one another or to smooth substrate surfaces, comprising at least one polyolefin which has been prepared by polymerization in the presence of metallocene as catalyst and has a ring/ball softening point in the range from 50 to 165° C. and a melt viscosity measured at a temperature of 170° C. in the range from 20 to 40 000 mPa·s.
