  • Membrane closure structure
    Patent number: 4381848
    Abstract: A retortable membrane closure structure for containers is disclosed which includes a first adhesive layer, an intermediate layer, a second adhesive layer and an outer barrier layer. Bond strengths and tear strengths of the layers are selected such that upon peeling the membrane from a container to which it was sealed initial failure occurs within the intermediate layer, followed by failure between the second adhesive layer and the intermediate layer, providing a clean peel between the layers.
