A closure mechanism for a reclosable pouch includes a female profile having first, second, and third legs extending from a base of a first closure element. A first sealing flange is attached to each of the first and second legs, with a slit disposed through the first sealing flange to define a first sealing flap that depends from the first leg and a second sealing flap that depends from the second leg. A second sealing flange is attached to each of the second and third legs, with a slit disposed through the second sealing flange to define a third sealing flap that depends from the second leg and a fourth sealing flap that depends from the third leg. A first male profile extends from a base of a second closure element. The first male profile engages a portion of the first and second sealing flaps to form a seal therebetween when the respective male and female profiles are occluded. A second male profile extends from the base of the second closure element. The second male profile engages a portion of the third and fourth sealing flaps to form a seal therebetween when the respective male and female profiles are occluded.
