The method according to claim 1, wherein the plate element has a first face and an opposite second face, wherein the corrugations are formed in one direction only along the first face, while being open along the opposing second face, wherein the plate element comprises a single layer structure. 6. The method according to claim 1, wherein the plate is molded. 7. The method according to claim 1, wherein the plate is perforated by a needle-roller process. 8. The method according to claim 1, wherein the perforation is formed during formation of the plate element. 9. A heat exchanger element comprising a plate element with defined outer dimensions and corrugations to increase the exchange surface in the area within a border, said border being defined by a peripheral rim that extends completely around the area containing the corrugations, the peripheral rim including a first portion that is open along a corresponding edge of the plate and defines one of an inlet and an outlet of a flow channel, the first portion lying in a different plane relative to adjacent portions of the peripheral rim so as to represent a locally deformed area of the peripheral rim, said inlet or outlet of the flow channel being spaced from the corrugations and is therefore only defined by a non-corrugated portion of the plate, the plate element being further defined by a first face and a second face, said plate element being made from a material having sensible energy recovery capability, and said plate element has perforations in predefined first areas and in predefined dimensions, each perforated area providing a plurality of perforations, each perforation being made so as to extend from the first face to the second face, said perforations being filled with a polymer with latent energy recovery capability, wherein the polymer comprises a sulfonated block copolymer that has a water vapor transmission rate suitable for use in a total energy recovery ventilator (ERV). 10.
