Abstract
A multi-ply laminated wall structure, especially for a bag for popping popcorn in a microwave oven, has at least two plies of paper secured together with spaced patches of adhesive to form a unitary laminated structure that has greater flexibility and lower cost than a conventional bag wall. The adhesive covers from about 25% up to about 60% of the confronting area between the plies, and the unsecured areas between the patches of adhesive are in communication with one another. The outer ply is gas permeable so that gas is permitted to escape from between the plies, and any moisture between the plies escapes through the unsecured areas between the patches of adhesive at the ends of the laminated structure.
