Abstract
A plastic, easy-opening closure for a retortable container and a method for sealing are provided. The closure includes a plastic membrane having an outer layer of polypropylene, a first tie layer, an intermediate layer formed of EVOH, a second tie layer, an inner layer formed of polypropylene, and a peel-seal layer. The peel-seal layer can be formed of high density polyethylene or polypropylene with a contaminant dispersed therein so that the closure can be easily removed from the container for opening.
