An airtight closure mechanism for a reclosable pouch includes first and second complementary closure elements, the first closure element comprising a first interlocking profile and the second closure element comprising a complementary second interlocking profile. First and second sealing sections are disposed on respective complementary sides of the first and second interlocking profiles. The first sealing section includes a first protuberance having a first distal surface, a second protuberance having a second distal surface, and a sealing flange attached to and extending between the first and second distal surfaces of the first and second protuberances, respectively. The second sealing section includes a sealing member disposed on a base of the second closure element. The sealing member is located a distance from the second interlocking profile that places a distal surface thereof between the first and second protuberances when the first and second interlocking profiles are occluded. Additionally, when the first and second interlocking profiles are occluded, the distal surface urges against the sealing flange to form an airtight seal therebetween.
