CA 2401520

A laminated sheet having cloth-like texture can be obtained with polymeric film constructed of at least two layers being laminated over a non-woven fabric, while part of the polymeric film layer contacting the non- woven fabric penetrates into spaces between the fibers of the non-woven fabric to integrate said members into a combined body. It is suitable for uses as packaging materials and personal hygiene products. All the polymeric film layers are formed from resin containing inorganic filler, and when the laminated sheet is subjected to a drawing process, the resulting laminated sheet imparts high water vapor transmission rate and high hydrostatic head. In case the polymeric film layer does not contain inorganic filler, laminated sheets having high stretch can be obtained.
