The present invention relates to a perforated thermoplastic structure comprising at least a first layer () and a plurality of perforations, which extend through the first layer (). The perforations have a three-dimensional, preferably approximately conical or cylindrical shape (). A second layer forms an inner surface () of the shape (), whereas the first layer forms an outer surface () of the shape (). The first layer contains a thermoplastic material, whose melting point is lower than a melting point of the thermoplastic material of the second layer.

Perforated laminate

The present invention relates to a multilayer producthaving at least one first layer, an absorbent intermediate layerand a second layer, whereby at least the first layercontains at least one first materialand one second material. The first layerand/or the second layeris at least partially liquid permeable. The first materialhas a higher melting point than the second material, with the second materialcreating a bond to the second layer
