ABSTRACT:
A peelable seal includes four layers. The first layer includes first and second alternating ribs. The first ribs comprise a first material, and the second ribs comprise a second material. The first material bonds well with the closure profiles. The second material bonds well with the third and fourth layers. The first material does not bond well with the second material. Thus, the bond strength is lower between the first and second ribs and between the third and fourth ribs than between the first and third ribs and the closure profiles and between the second and fourth ribs and the third and fourth layers. In this process, the strength of the peelable seal is controlled during the extrusion process rather than being subjected to the variations in the manufacturing process. Alternatively, the peelable seal includes six layers. The first and second layers bond well with the closure profiles. The third and fourth layers bond well with the fifth and sixth layers. The first layer does not bond well with the third layer and the second layer does not bond well with the fourth layer. Thus, the bond strength is lower between the first and third layers and between the second and fourth layers.
