A one-way valve for mounting over an aperture formed on a food package for cooking, storing and/or heating of ready-to-eat food, the one-way valve comprising: a first membrane comprising a top surface and a bottom surface , wherein the bottom surface is adapted to be fixed to the food package; a second membrane comprising an upper surface and a lower surface ; wherein the lower surface of the second membrane is adhered to the top surface of the first membrane by means of: a first adhesive arranged on a center portion and each of two lateral edge portions of an overlapping surface area of the first membrane and second membrane, wherein the center portion and the two lateral edge portions are non-overlapping, and wherein the lateral edge portions extend from a first longitudinal edge to an opposite second longitudinal edge of the overlapping surface area; a second adhesive arranged on each of two intermediate portions between each lateral edge portion and the center portion , the two intermediate portions extending from the first longitudinal edge to the opposite second longitudinal edge of the overlapping surface area, and wherein a bond strength of the second adhesive is stronger than that of the first adhesive ; wherein the first membrane comprises an opening such that a canal is formed between the first membrane and the second membrane when the one-way valve is mounted over the aperture of the food package and a gas pressure inside the food package exceeds a threshold value, wherein the canal extends from the opening to at least one of the first longitudinal edge and the second longitudinal edge via the center portion of the overlapping surface area. a first membrane comprising a top surface and a bottom surface , wherein the bottom surface is adapted to be fixed to the food package; a second membrane comprising an upper surface and a lower surface ; wherein the lower surface of the second membrane is adhered to the top surface of the first membrane by means of: a first adhesive arranged on a center portion and each of two lateral edge portions of an overlapping surface area of the first membrane and second membrane, wherein the center portion and the two lateral edge portions are non-overlapping, and wherein the lateral edge portions extend from a first longitudinal edge to an opposite second longitudinal edge of the overlapping surface area; a second adhesive arranged on each of two intermediate portions between each lateral edge portion and the center portion , the two intermediate portions extending from the first longitudinal edge to the opposite second longitudinal edge of the overlapping surface area, and wherein a bond strength of the second adhesive is stronger than that of the first adhesive ; a first adhesive arranged on a center portion and each of two lateral edge portions of an overlapping surface area of the first membrane and second membrane, wherein the center portion and the two lateral edge portions are non-overlapping, and wherein the lateral edge portions extend from a first longitudinal edge to an opposite second longitudinal edge of the overlapping surface area; a second adhesive arranged on each of two intermediate portions between each lateral edge portion and the center portion , the two intermediate portions extending from the first longitudinal edge to the opposite second longitudinal edge of the overlapping surface area, and wherein a bond strength of the second adhesive is stronger than that of the first adhesive ; wherein the first membrane comprises an opening such that a canal is formed between the first membrane and the second membrane when the one-way valve is mounted over the aperture of the food package and a gas pressure inside the food package exceeds a threshold value, wherein the canal extends from the opening to at least one of the first longitudinal edge and the second longitudinal edge via the center portion of the overlapping surface area. <EOS>
