Abstract
A method for creating peelable or frangible seals comprising the steps of: 1) selecting a first planar film with a polyethylene based resin disposed on its surface; 2) defining a frangible sealing zone on a surface of the first planar film; 3) heat sealing a second planar film to the frangible zone where the second planar film has a seal surface comprising a plurality of polymers; and 4) cooling the first and second planar films and frangible zone. A seal is created whereby peeling away the second planar film causes a rupture in the polymers disposed on the second planar film's surface.
