Abstract
Unitary films and laminates thereof are provided having at least first and second film segments which extend adjacent one another and are permanently joined together. The first and second film segments are joined at an interface, wherein at the interface a tip of the second segment overlaps the first segment in the cross-direction of the film. The film has a thickness “T” at the tip of the second segment, and the second segment has a thickness “t” at a distance T in the cross direction from the tip of the second segment. The ratio T/t is suitably greater than about 3. The unitary films and laminates thereof are well suited, for example, for use as outer covers in personal care articles.
