A method for manufacturing a closure constructed to be inserted and securely retained in a neck of a product-retaining container includes intimately combining a plurality of coated particles (each comprising a cork material core and a first plastic material) with a second plastic material, and other optional constituents; heating the composition to form a melt; extruding or molding a closure precursor from the melt; and optionally cutting and/or finishing the closure precursor. A composition for use in manufacturing a closure includes a plurality of coated particles (each comprising a cork material core and a first plastic material) with a second plastic material, and one or more blowing agents. Methods for producing particulate material, cork composite material, and additional method for producing closures are also provided.

A process for in-line extrusion of polymeric coatings onto roofing shingles during manufacturing includes moving a web of shingle substrate material in a downstream direction and extruding a liquefied coating of polymeric material onto at least one surface of the moving web to form a thin film. The liquefied coating may be a molten polymeric material that forms a thin film on a back surface of the shingle material to prevent sticking and eliminate the need for a traditional back dusting with material such as powdered stone. The polymeric film further may be applied to the substrate material in lieu of a saturation coating of asphalt, thus reducing cost and weight while providing a comparable moisture barrier and a lighter more flexible shingle.

An optical fiber cable production method includes: feeding a core including optical fibers; winding a reinforcing wrap around the core and forming an overlapping portion in which end portions of the reinforcing wrap overlap each other at a portion of the reinforcing wrap in a circumferential direction; and performing extrusion molding of a sheath on an outside of the reinforcing wrap. The overlapping portion extends in a longitudinal direction of the optical fibers. In the performing extrusion molding, a resin that forms the sheath is inserted into a portion of the overlapping portion.

Polyethylene compositions described herein have a density from about 0.900 g/cm.sup.3 to about 0.950 g/cm.sup.3, a MI (I.sub.2, 190° C., 2.16 kg) from about 0.1 g/10 min to about 10 g/10 min, an MIR (I.sub.21/I.sub.2) from about 25 to about 80, an M.sub.z greater than or equal to about 150,000 g/mol, and either an M.sub.z/M.sub.n ratio greater than or equal to about 8.0, an M.sub.z/M.sub.w ratio greater than or equal to about 2.4, or an (I.sub.2*M.sub.z/M.sub.n) from about 3 to about 100. The polyethylene compositions are useful in wire and cable, tape, and filament applications, and could be produced using a gas phase or slurry phase, preferably gas phase, polymerization process.
