ABSTRACT:
Flexible, creased material in sheet or web form for use in the manufacture of liquid-tight packing containers of good dimensional rigidity comprises one or more base layers laminated to one another. The base layer is a mineral-filled thermoplastics material comprising between 50 and 80% calculated on the total weight of the mixture, of an inorganic, particulate mineral filler. The thermoplastics material is chosen among propylene-based polymers with a melt index of between 0.5 and 5 according to ASTM (2.16 kg, 230.degree. C.) and the base layer or base layers are provided with a pattern of crease lines which have been formed by plastic deformation in connection with or immediately after the extrusion of the base layer or base layers.
