    Abstract: The present invention discloses a process for forming a biaxially oriented film. The process includes first selecting a polyolefin resin wherein said polyolefin resin comprises a linear low density polyethylene resin characterized by having from 9 to 35 weight percent of the total weight of linear low density polyethylene resin eluting from a CEF at a temperature greater than 97.0° C.; and further characterized by having a CDR of from 33 to 80 and a Mw Ratio of from 0.15 to 0.45. Next a film is formed from the polyolefin resin selected in the first step. Finally the film formed in the second step is oriented in a sequential manner. The films produced by this process are characterized by having an ultimate elongation at least 1.5 times greater in the MD as compared to the CD and the 2% secant modulus is a least 1.25 times greater in the CD as compared to the MD. The films are further characterized by having free residual shrinkage of less than 10% in the MD and less than 10% in the CD when exposed to a temperature of 90° C. for 10 minutes.

    Abstract: A method to determine the weight percent of an “amorphous” fraction in an olefin-based polymer composition, comprising one or more olefin-based polymers; said method comprising the following steps: a) dissolving the olefin-based polymer composition in an organic solvent to form a polymer solution; b) injecting at least a portion of the polymer solution onto a support material, and wherein the support material has a Co-crystallization Index (CI) value from 0.70 to 1.20; c) cooling the support material at a rate greater than, or equal to, 0.2 C/min; d) increasing the temperature of the support material to elute the polymers of the olefin-based polymer composition; e) generating a chromatogram; f) determining the peak area of the first elution from its lower integration limit to its upper integration limit; g) calculating the “amorphous” fraction” based on the following Equation A below: wt % “amorphous” fraction=PAamorphous/PAtotal×100 (Eqn. A); wherein PAamorp=peak area of the first elution, and PAtotal #191=total peak area of the polymers of the olefin-based polymer composition.
