METHOD FOR MAKING A FILTERING ELEMENT AND FILTERING ELEMENT

摘要

A method for making a filtering element from a film of non-woven material, the filtering element being associable with a container for containing and/or retaining a product, including hot pressing at least one defined portion of the film or of the filtering element so as to obtain a pressed portion in which fibres, in particular synthetic and/or plastic fibres, of at least one external surface layer of the non-woven material are compacted and pressed together and in which a thickness of the non-woven material is reduced by a percentage between 30 and 50%.
