ABSTRACT:
A non-invasive tear mechanism for a flexible packaging, the non-invasive tear mechanism comprises a plurality of junctions formed in the flexible packaging that form a line of weakness in the packaging. The junctions are non-invasive in that the flexible packaging is not cut or scored when the non-invasive tear mechanism is formed. An apparatus for producing a non-invasive tear mechanism in a flexible packaging comprising a carriage, a horn mounted on the carriage, and an anvil having an anvil work surface with a plurality of protuberances extending from it mounted on the carriage. An actuating rod is mounted on the carriage and used for moving the horn and anvil. The protuberances form the non-invasive tear mechanism in the flexible packaging when the horn is activated and the flexible packaging is fused at junctions that correspond with the protuberances.
