ABSTRACT:
A packing comprising first and second opposed surfaces in a closure area of the packing has profiled portions secured to and extending over each of the opposed surfaces, which profiled portions are adapted to be releasably interengaged to permit connection and disconnection of the opposed surfaces. The profiled portions are each formed integrally with an outer layer of a strip material secured to the associated one of the opposed surfaces. The outer layer of the strip material is formed of a material well suited for forming a peel seal weld with the other opposed surface of the packing, such as a portion of the outer layer of the opposing strip material. The outer layer of each strip material is secured to the one of the first and second opposed surfaces via a base layer of the strip material to which the outer layer is secured by means of a non-peel seal type connection. As a result, the sheete material of the packing, a bag for example, need not be formed of a peel seal weldable material.
