1. A method of making a multi-laminate film comprising:
positioning a first biaxially oriented film for lamination, the first biaxially oriented film having a first machine direction angle, and a first cross machine direction angle perpendicular to the first machine direction angle;
positioning a first spiral cut oriented film for lamination, the first spiral cut oriented film having a second machine direction angle different than the first machine direction angle and the first cross machine direction angle; and
positioning at least one of a second biaxially oriented film or a second spiral cut oriented film for lamination, the second biaxially oriented film having the first machine direction angle;
laminating the first biaxially oriented film, the first spiral cut oriented film and the at least one of the second biaxially oriented film or second spiral cut oriented film together;
wherein the first biaxially oriented film has the first machine direction angle and the first cross machine direction angle prior to lamination with the first spiral cut oriented film and the one of the second biaxially oriented film or second spiral cut oriented film.
