This disclosure describes a packaging cushion constructed from polyethylene foam that is resistant to atmospheric pressure changes. The cushion is assembled from polyethylene foam tubes that act as a buffer and provide a cushioning effect for package contents due to an air cushion (suspension) within the tube and damping from the polyethylene foam. Since the air cushion is formed within unpressurized foam tubes, the cushion is resistant to ambient pressure changes. A foam layer with suitable openings is utilized to create a lattice like structure from the foam tubes. The cushion can be placed at any side of a package container.
