Laminated film with stretched layer

Abstract

Disclosed is a film ( 10 ) for the wrapping of objects. The film comprises a first film layer ( 12 ) made from an elastic material, a second film layer ( 14 ) made from a sturdy material, and a third layer ( 12 ) made from an elastic material, wherein the first and third film layers ( 12, 16 ) are stretched.

1 . A film for wrapping of objects, comprising:
 a first film layer made from an elastic material,   a second film layer made from a durable material,   a third film layer made from an elastic material,   wherein the second film layer is disposed between the first film layer and the third film layer, and the first film layer and the third film layer are stretched in a longitudinal direction.   
     
     
         2 . The film according to  claim 1 , wherein the first and third layers are stretched by 10%-50%. 
     
     
         3 . The film according to  claim 1 , wherein the second layer is made from a woven plastic material. 
     
     
         4 . The film according to  claim 1 , wherein the first and third layers are made from low density polyethylene. 
     
     
         5 . A system for manufacturing a film for wrapping of objects, comprising:
 a first roller running at a first speed positioned at a first position, the first roller adapted to feed a first layer film comprising an elastic material;   a second roller running at a second speed positioned at a first position, the second speed being higher than the first speed, the second roller adapted to feed a second film layer comprising a durable material;   laminating rollers positioned at a second position, the second position being downstream of the first position;   wherein,   the system further comprises a third roller running at the first speed, positioned at a first position,   the second roller is disposed between the first and the third roller, and   the laminating rollers are adapted to laminate the three layers into a film comprising three layers.   
     
     
         6 . A method for manufacturing a film for wrapping of objects comprising the steps of:
 providing and stretching a first film layer comprising an elastic material;   providing a second film layer comprising a durable material;   providing and stretching a third film layer comprising an elastic material, wherein the second film layer is provided between the first film layer and the third film layer,   laminating the layers together to form a laminated film,   wherein the stretching is performed in the longitudinal direction of the film.
