• wherein the sealed closure comprises a first portion having a first peel strength and a second portion having a second peel strength that is lower than the first peel strength;
• wherein at least a portion of a surface of the front wall is adapted to be separable from a portion of the back wall by applying the second peel strength;
• and
• wherein a difference between the first peel strength and the second peel strength is associated with a plurality of surface treatments applied to at least the interior surface portion of the front wall or the exterior surface portion of the back wall.
