摘要 |
<p>Flexible, creased material in sheet or web form for the manufacture of liquid-tight packing containers of good dimensional rigidity, which material comprises one or more base layers laminated to one another of a mineral-filled thermoplastics comprising between 50 and 80% calculated on the total weight of the mixture , of an inorganic, particulate mineral filler. Said thermoplastics is chosen among propylene-based polymers with a melt index of between 0,5 and 5 according to ASTM (2,16kg, 230 DEG C) and said 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 said base layer or base layers.</p> |
