ABSORBENT PRODUCT, CONTAINING THE POROUS POLYOLEFIN FILM Russian patent published in 2017 - IPC A61F13/53 A61L15/22 C08J5/18 C08J9/00 B29C55/00 

FIELD: personal care items.

SUBSTANCE: invention relates to the absorbent product, containing the absorbent element, disposed between the backing and the top layer, wherein the absorbent product contains a film, formed from the thermoplastic composition, which contains a continuous phase, that includes the polyolefin matrix polymer and the nanoinclusions additive, dispersed in the continuous phase in the form of discrete domains, where the porous network is defined in the composition, which includes a plurality of nanopores with the average cross-section size is about 800 nanometers or less.

EFFECT: as a result of the porous network formation, the molecular orientation occurs, leading to strain hardening, which increases the mechanical strength.
