资源简介：
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.
