Abstract:
A personal hygiene article includes a chassis with a topsheet, a backsheet, and an absorbent component between the topsheet and the backsheet. At least one portion of the personal hygiene article includes a microporous film having an opaque, microporous region and at least one see-through region of lower porosity within the opaque, microporous region. The microporous film can include a beta-nucleating agent or can have thermally induced phase separation caused by a diluent. A container includes a microporous film enclosing at least one personal hygiene article. The microporous film has an opaque, microporous region and at least one see-through region of lower porosity forming a window within the opaque, microporous region. Methods of making the personal hygiene article and container are also described.
