Title (EN) SEGMENTED FILMS WITH HIGH STRENGTH SEAMS
(FR) FILMS SEGMENTÉS AVEC JOINTURES À HAUTE RÉSISTANCE
Abstract:
(EN) 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.
(FR) L'invention concerne des films monoblocs et des stratifiés de ceux-ci, comprenant au moins des premiers et deuxièmes segments de film qui s'étendent au voisinage les uns des autres et sont joints les uns aux autres de façon permanente. Les premiers et deuxièmes segments de film sont joints au niveau d'une interface caractérisée en ce qu'à l'interface, une extrémité du deuxième segment chevauche le premier segment dans la direction transverse du film. Le film présente une épaisseur "T" à l'extrémité du deuxième segment et le deuxième segment présente une épaisseur "t" à une distance T de l'extrémité du deuxième segment dans la direction transverse. Le rapport T/t approprié est supérieur à environ 3. Les films monoblocs et leurs stratifiés conviennent avantageusement, par exemple, à une utilisation comme revêtements extérieurs dans des articles de soins personnels.
