Methods are provided that facilitate the selection of a film structure for use in a package. In one aspect, a method of selecting a film structure for use in a package comprises determining a critical impact direction of a package by finite elemental method (FEM) analysis, wherein the package has a predetermined volume, a predetermined shape, and a predetermined fill material; determining one or more desired tensile properties of a film structure to use in the package based on the critical impact direction, wherein the one or more desired tensile properties comprise at least one of toughness in the machine direction, toughness in the cross direction, elongation at break in the machine direction, elongation at break in the cross direction, stress at break in the machine direction, and stress at break in the cross direction; and selecting a film structure based on the one or more desired tensile properties.

Methods for selecting film structures for packages

A building structure includes a framework of: (a) metal studs having walls that define an interior channel; (b) a cellular backing material extending lengthwise within the interior channel of at least a portion of the metal studs; (c) a thermally insulating layer extending over multiple metal studs; (d) fasteners extending through the thermally insulating layer, through a wall of a metal stud and into the cellular backing material within the interior channel of the metal stud; and (e) a cladding attached to the framework of metal studs by means of the fasteners.

The present invention includes an article of manufacture with a layer with a plurality of corrugations to form an energy absorbing structure, where each corrugation has a floor and two walls connecting the floor to the base layer and the length of each corrugation is longer than the widest width of the corrugation. The present invention also includes an energy absorbing structure with a multi-layer energy absorber having a layer with a plurality of surface features and a second layer with a second plurality of surface features wherein the surface features of one layer are nested within the surface features of the other layer such that the base layers are adjacent to each other. The present invention also includes a single step method of manufacturing the energy absorbers including forming a two layer material in a single step. Further, the present invention includes a method of absorbing impact energy that involves generating heat through friction between surface features on a pair of base layers.
