The invention relates to a novel gas filter structure, a filtering method and a method of producing the filter structure. The structure according to the invention comprises a planar, porous isolation material layer (12) having two opposing surfaces. According to the invention both surfaces of the isolation material layer (12) comprise a porous conductive layer (14, 16) comprising a porous filtering matrix treated with a conductive material. The conductive material consists of a material different from the support matrix. By means of the conductive layers it is possible to create in the isolation material an electric field that considerably improves the filtering efficiency of the isolation material, especially for small particles.

摘要:
A microstructure area (201) providing a first diffractive visual effect is produced on the surface layer (240) of a paper or cardboard substrate (230) of a product (200). In addition, a bulge (206) or a recess (207) having a second microstructure area (202) is produced on the surface layer (240), wherein a doubly curved portion (203) is located between the first (201) and the second (202) microstructure areas. Said combination of the bulge (206) / recess (207), microstructure areas (201 , 202) and doubly curved portion (203) makes counterfeiting of the product (200) difficult and provides a special visual effect.
