摘要: 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.
