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.

The invention provides an oriented article, for example, a yarn, tape or filaments made from a three component polymer blend.

Ethylene polymer blends and oriented articles with improved shrink resistance

Provided is an artificial turf yarn having improved heat resistance, durability, softness and extensibility. The artificial turf yarn contains two components: an olefin block copolymer (OBC) and a linear low density polyethylene (LLDPE). The yarn includes from about 10 wt % to about 80 wt % of the OBC and from about 20 wt % to about 90 wt % of the LLDPE which produces an artificial turf yarn with improved softness and toughness while maintaining heat resistance.
