ABSTRACT:
A roll of continuous laminated web product usable for forming a flexible package includes a first continuous flexible web formed of a gas barrier material adapted to form an inner bag of the package, and a second continuous flexible web adapted to form an outer bag of the package. The first and second webs are adhered together by adhesive bonds in the form of a discrete pattern of bonded areas which repeats in the machine-direction of the laminated web construction to define a plurality of sequentially disposed, dual walled sheets between such discrete patterns of bonded areas. Each of the discrete patterns of bonded areas includes discrete bonds which are spaced-apart from each other in the cross-machine-direction of the roll to define at least one passageway between the discrete bonds. The first continuous flexible web and the second continuous flexible web of the roll are of different materials to preclude sealing of the at least one passageway when a bonding energy is applied to the dual walled sheets for sealing upper and lower sections of the package with the contents in the inner bag of the package being under vacuum.
