A multilayer film includes an outer foam layer and a gas barrier layer. The multilayer film may also include at least one tie layer and at least one inner layer, and can be configured to have various film layer constructions. For example, the multilayer film can be configured as a five-layer, six-layer, or seven-layer films. The multilayer film can provide unique texture, softness, quietness, gas barrier properties, light weight and low cost per volume. Further, one or more layers of the multilayer film can contain a vinyl-bond rich triblock copolymer to provide sound absorbing properties.
