    摘要： A gas permeable package is provided that is comprised of a bonded, gas permeable, fibrous sheet material consisting of continuous lengths of bonded plexifilamentary fibril strands of a polyolefin polymer and a pigment. The polyolefin comprises at least 90% by weight of the fibril strands and the pigment comprises between 0.05% and 10% by weight of the fibril strands. The polyolefin polymer is preferably selected from the group of polyethylene, polypropylene, and copolymers comprised primarily of ethylene and propylene units, and is more preferably polyethylene. The pigment is preferably titanium dioxide. The fibrous sheet material has a basis weight of less than 85 g/m2, a delamination strength of at least 60 N/m, and an opacity of at least 90% if the sheet has a delamination strength less than 120 N/m, an opacity of at least 85% if the sheet has a delamination strength between 120 N/m and 150 N/m, and an opacity of at least 80% if the sheet has a delamination strength greater than 150 N/m.

    摘要： A method of converting a plastics material into a yarn in which the plastics material comprises one or more polymers selected from the group consisting of nylon, polyesters, polyethylene, polyvinyl chloride, polyphenylene sulphide, polystyrene. The method comprises heating the material to melt it, pumping the melted material through an extruder to form an extruded filament, and cooling the extruded filament. The cooled filament is passed through a first draw roller assembly while elevating the temperature of the filament. The filament is then heated in a heating zone as it exits the first draw roller assembly and, thereafter, the filament is passed through a second draw roller assembly operating at a different linear speed to the first draw roller assembly. The filament is spooled after exiting the second draw roller assembly.

    摘要： For manufacturing tape or yarns, plastic polymer material is extruded into a film (20, 21) having a pattern of parallel, longitudinal, alternating ribs (31, 32) and deep, narrow grooves (33, 34) on each of its two opposite sides, at least a plurality of the grooves (33, 34) in one side each being located diametrically opposite one of the grooves (34, 33) in the other, opposite side. Yarns and tapes obtained in the form of or from such a film typically have a substantially improved tensile strength and are more supple and smooth.
