Apparatus and methods for producing folded edges in a film in-process, and compositions of such film are provided. A method of folding edges includes: separating a first idler roll and a second idler roll by a first distance; positioning a plurality of folding guides between the first idler roll and the second idler roll; separating adjacent sections of film having a majority layer comprising a Ziegler Natta catalyzed linear low density polyethylene copolymer resin having molecules that inherently lack long chain branching, wherein a majority of said molecules are oriented in a substantially longitudinal direction due to an induced strain, and inducing two folds with each folding guide, thereby causing an edge of each section of film to turn under 180° and cling to a bottom surface of the section of film; and moving the adjacent sections of film from the folding guides to the second idler roll.
An apparatus for producing folded edges in a film in-process, the apparatus comprising:
