Abstract
Methods for creating multi-layered bags with increased or maintained strength involve forming a ribbed pattern in one or more film layers of a multi-layered bag. The method also includes non-continuously laminating the film layers of the multi-layered bag together. In one or more implementation, a transverse direction ring rolling process forms the ribbed pattern and bonds the film layers together. In one or more additional implementations, the ribbed pattern and lamination are formed separately. Still further implementations include forming network patterns one or more film layers of a multi-layered bag. Multi-layered bags formed in accordance with one or more implementations of the present invention include one or more of increased strength or reduced basis weight.
