Closure system for pouch or container

A bag made entirely from an elastomer, comprising:

• a body comprising a front wall and a rear wall, the body including a longitudinal axis that extends vertically between a top side of the body and a bottom side of the body opposite the top side;
• and
• a closure system, comprising:
• a front side having a front sealing profile that includes a male closure element extending from a thickened region;
• and
• a rear side having a rear sealing profile that includes a female closure element and defining an opening into a cavity,
• wherein the closure system includes a left tab and a right tab that that each extend in an outward direction,
• wherein each of the front sealing profile and the rear sealing profile extends uninterrupted longitudinally along the body between the left tab and the right tab, and
• wherein each of the left tab and the right tab defines a height of between about 20 millimeters (mm) and about 30 mm as measured in a direction parallel to the longitudinal axis.

• wherein in a closed configuration of the closure system, a centerline extends through the opening, the cavity, and the thickened region, and the male closure element is received within the cavity along an entirety of the rear sealing profile,
• wherein in an open configuration of the closure system, the male closure element is disengaged from the female closure element along at least a portion of the rear sealing profile, and
• wherein an entire thickness of the front wall measured in a direction parallel to the centerline is between about 35% and about 80% of a thickness of the thickened region measured in a direction parallel to the centerline.
