==Original Abstract Submitted==

A multilayer film comprising at least three film layers including: (a) at least a first polyolefin film layer, wherein the first polyolefin film layer comprises a first outer film layer; (b) at least a second polyolefin film layer, wherein the second polyolefin film layer comprises a core film layer; and (c) at least a third polyolefin film layer, wherein the third polyolefin film layer comprises a second outer film layer; wherein the at least a third polyolefin film layer is the same or different than the at least first polyolefin film layer; wherein the at least second core polyolefin film layer is disposed in between, and separates, the first and third film layers; wherein the first, second and third film layers are contacted together to form a multilayer film structure; wherein at least one of the polyolefin film layers of the three-layer film structure is prepared from a polymer blend composition comprising: (i) at least a first ethylene-based polymer resin; wherein the at least first ethylene-based polymer resin comprises a catalyzed linear low density polyethylene having an altered molecular structure prepared using a Ziegler-Natta Catalyst System 1, which is prepared as described in Preparation 1 in the description; and (ii) at least a second ethylene-based polymer resin; wherein the at least second ethylene-based polymer resin comprises a low density polyethylene resin; and wherein the multilayer film comprising a catalyzed linear low density polyethylene having an altered molecular structure prepared using a Ziegler-Natta Catalyst System 1, which is prepared as described in Preparation 1 in the description, exhibits at least a 10 percent increase in puncture resistance compared to the puncture resistance of a multilayer film that include a catalyzed linear low density polyethylene resin having a non-altered molecular structure prepared using a Ziegler-Natta catalyst; a process for preparing the multilayer film; and an article made from the multilayer film.
