Abstract
A lid for a packaging container including an easy opening tear-open part which is surrounded by a weakened line. The lid is molded from a compound material, which has an outer carrier layer of plastic, a middle barrier layer of metal foil and an inner heat-sealing layer of a thermoplastic material. In order to facilitate the initial tear of the tear-open part, the middle barrier layer is also thinned or ruptured at least in the starting segment in a location coinciding with the weakening line in the carrier layer.
