Laminated film

Abstract

A multi-laminate film includes a first biaxially oriented film having a first machine direction angle and a first spiral cut oriented film having a second machine direction angle different than the first machine direction angle. The multi-laminate film also includes at least one of a second biaxially oriented film having the first machine direction angle or a second spiral cut oriented film. 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 are laminated together.

What is claimed is: 
     
         1 . A multi-laminate film comprising:
 a first biaxially oriented film having a first machine direction angle;   a first spiral cut oriented film having a second machine direction angle different than the first machine direction angle; and   at least one of a second biaxially oriented film having the first machine direction angle or a second spiral cut oriented film;   wherein 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 are laminated together.   
     
     
         2 . The multi-laminate film of  claim 1 , wherein the at least one of the second biaxially oriented film or second spiral cut oriented film is the second biaxially oriented film, the first spiral cut oriented film being laminated between the first and second biaxially oriented films. 
     
     
         3 . The multi-laminate film of  claim 1 , wherein the at least one of the second biaxially oriented film or second spiral cut oriented film is the second spiral cut oriented film, the first biaxially oriented film being laminated between the first and second spiral cut oriented films. 
     
     
         4 . The multi-laminate film of  claim 3 , wherein the second spiral cut oriented film has the second machine direction angle. 
     
     
         5 . The multi-laminate film of  claim 3 , wherein the second spiral cut oriented film has a third machine direction angle different than the first and second machine direction angles. 
     
     
         6 . The multi-laminate film of  claim 5 , wherein the second machine direction angle is within the inclusive range of about +30° to about +60° and the third machine direction angle is within the inclusive range of about −30° to about −60°. 
     
     
         7 . The multi-laminate film of  claim 1 , wherein the second machine direction angle is within the inclusive range of about +30° to about +60°. 
     
     
         8 . The multi-laminate film of  claim 1 , wherein the second machine direction angle is within the inclusive range of about −30° to about −60°. 
     
     
         9 . The multi-laminate film of  claim 1 , wherein 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 each comprise high density polyethylene (HDPE) or linear low density polyethylene (LLDPE). 
     
     
         10 . The multi-laminate film of  claim 1 , wherein 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 each comprise two skins layers and a core layer disposed between the two skins layers. 
     
     
         11 . A multi-laminate film comprising:
 a plurality of films laminated together, each film having a machine direction angle, wherein the machine direction angles of at least two films of the plurality of films are different from each other.   
     
     
         12 . The multi-laminate film of  claim 11 , wherein the films of the plurality of films are arranged such that no two adjacent films of the plurality of films have the same machine direction angle. 
     
     
         13 . The multi-laminate film of  claim 12 , wherein each film of the plurality of films is a biaxially oriented film or a spiral cut oriented film. 
     
     
         14 . The multi-laminate film of  claim 13 , wherein the plurality of films includes at least two biaxially oriented films. 
     
     
         15 . The multi-laminate film of  claim 13 , wherein the plurality of films includes at least two spiral cut oriented films. 
     
     
         16 . The multi-laminate film of  claim 13 , wherein the films of the plurality of films are arranged to alternate between biaxially and spiral cut oriented films. 
     
     
         17 . The multi-laminate film of  claim 13 , wherein the plurality of films includes three to nine films. 
     
     
         18 . The multi-laminate film of  claim 15 , wherein the machine direction angle of the at least two spiral cut oriented films are the same. 
     
     
         19 . The multi-laminate film of  claim 15 , wherein the machine direction angle of the at least two spiral cut oriented films are different. 
     
     
         20 . The multi-laminate film of  claim 13 , wherein each film of the plurality of films comprises high density polyethylene (HDPE) and/or linear low density polyethylene (LLDPE).
