Abstract
A molded part is made by cold-stretching a nonwoven web so as to rupture fibers or filaments thereof, laminating to a face of the cold-stretched nonwoven web a stretchable plastic film, and then inserting the laminated nonwoven web and film into a mold cavity with the film juxtaposed with an inner surface of the cavity and the cold-stretched web turned inward. This mold cavity is then filled a polymer melt to press the film against the inner mold surface while forcing the melt to penetrate the nonwoven web.
