ABSTRACT:
A tear template is provided for use in an easy-open container closure system of the type employing an exterior tape and an interior sheet material. The tear template, which is located between the exterior tape and interior sheet material, advantageously provides a closure system which is better able to withstand excessive internal container pressures without detracting from the easy open character of the closure system.
