Document Type and Number:
Japanese Patent JP2007533487
Kind Code:
A
Abstract:
This invention relates to a process for preparing breathable, elastic polyolefin films, including the steps of blow molding a mixture of olefins, styrenic thermoplastic elastomers and filler to facilitate the generation of porosity by stretching, squeezing the tubular to obtain a flat film, heating the flat film to the softening point, pressing the flat film, cooling the flat film to a temperature of 8 to 30° C., stretching the film in the transverse and/or longitudinal directions to make it breathable; it is also shown a plant for producing a breathable elastomeric polyolefin film and the use of a mixture of olefins, styrenic thermoplastic elastomers and filler to produce a breathable elastic film.
