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.

The concepts herein relate to a closing element (1) for containers for liquids, in particular bottles. The closing element (1) comprises at least a cork sheet (2) having two opposite main faces (2a, 2b) and at least a layer of insulating material (7), impermeable to liquids and to air and/or gases, coupled to the cork sheet (2). The layer of insulating material (7), at least partly covers at least one of said two main faces (2a, 2b). The cork sheet (2) and the layer of insulating material (7) are rolled so as to define the closing element (1) by an alternated winding of the cork sheet (2) and the layer of insulating material (7), and the layer of insulating material (7) and the alternated winding are configured and predisposed to make the closing element (1) impermeable or to liquids and air and/or gases. The mechanical winding is guaranteed by a partial and spotted gluing of the surfaces, usually only at the external end thereof.
