Multi-layer wrap

Abstract

A stretchable multi-layer wrap is provided. The wrap comprises a first film, which comprises an inside cling surface, a second film, which comprises an inside cling surface. The second film inside cling surface engages the first film inside cling surface. The wrap also comprises a plurality of longitudinal ribs that are co-aligned with a longitudinal axis of the wrap. The ribs are disposed between the engaged cling surfaces and spaced so as not to cause disengagement of the cling surfaces.

I/we claim: 
     
         1 . A stretchable multi-layer wrap comprising:
 a first film comprising an inside cling surface;   a second film comprising an inside cling surface, the second film inside cling surface engaging the first film inside cling surface; and,   a plurality of longitudinal ribs co-aligned with a longitudinal axis of the wrap, the ribs being disposed between the engaged cling surfaces and being spaced so as not to cause disengagement of the cling surfaces, the stretchability of the ribs limiting the stretching of the wrap.   
     
     
         2 . A stretchable multi-layer wrap according to  claim 1 , wherein the first and second films are pre-stretched films and further stretching of the wrap is limited by the stretching properties of the ribs. 
     
     
         3 . A stretchable multi-layer wrap according to  claim 1 , wherein the wrap further comprises:
 a third film comprising a cling surface and the second film further comprises an outside cling surface, opposite the inside cling surface, the third film cling surface engaging the second film outside cling surface; and,   a fourth film comprising a cling surface and the first film further comprises an outside cling surface, opposite the inside cling surface, the fourth film cling surface engaging the first film outside cling surface.   
     
     
         4 . A stretchable multi-layer wrap according to  claim 3 , wherein the third film further comprises a rust inhibiting agent. 
     
     
         5 . A stretchable multi-layer wrap according to  claim 4 , wherein the rust inhibiting agent is applied to a surface opposite the third film cling surface. 
     
     
         6 . A stretchable multi-layer wrap according to  claim 4 , wherein the rust inhibiting agent is integrally formed with the third film. 
     
     
         7 . A stretchable multi-layer wrap according to  claim 6 , wherein the rust inhibiting agent comprises a vapour corrosion inhibitor. 
     
     
         8 . A stretchable multi-layer wrap according to  claim 1 , wherein the first and second films are similarly composed. 
     
     
         9 . A stretchable multi-layer wrap according to  claim 8 , wherein the films comprise a low density polymer. 
     
     
         10 . A stretchable multi-layer wrap according to  claim 9 , wherein the low density polymer comprises a low density polyethylene. 
     
     
         11 . A stretchable multi-layer wrap according to  claim 1  further comprising a plurality of transverse ribs extending between and interconnecting the longitudinal ribs. 
     
     
         12 . A stretchable multi-layer wrap according to  claim 11 , wherein each respective longitudinal rib comprises an interwoven plurality of rib tapes. 
     
     
         13 . A stretchable multi-layer wrap according to  claim 12 , wherein each respective transverse rib comprises a rib tape. 
     
     
         14 . A stretchable multi-layer wrap according to  claim 13 , wherein the rib tapes comprise one of a low density polymer, a high density polymer and combinations thereof. 
     
     
         15 . A stretchable multi-layer wrap according to  claim 14 , wherein the high density polymer is a high density polyethylene. 
     
     
         16 . A stretchable multi-layer wrap according to  claim 1 , wherein the wrap further comprises vents arranged on the wrap so as to permit venting of a wrapped item. 
     
     
         17 . A stretchable multi-layer wrap according to  claim 16 , wherein the vents comprise one of slits, holes and combinations thereof 
     
     
         18 . A stretchable multi-layer wrap according to  claim 3 , wherein the wrap further comprises a label layer positioned between the first and fourth films, the label layer comprising indicia indicating one of use information for the multiplayer wrap, branding information for an item to be wrapped, location information for an item to be wrapped and combinations thereof. 
     
     
         19 . A stretchable multi-layer wrap comprising:
 a plurality of cling films, each film comprising respective opposing cling surfaces, the films being arranged so as to effect cling surface laminar engagement of the films; and,   a plurality of longitudinal ribs co-aligned with a longitudinal axis of the wrap, the ribs being disposed between the engaged cling surfaces and being spaced so as not to cause disengagement of the cling surfaces, the stretchability of the ribs limiting the stretching of the wrap.   
     
     
         20 . A stretchable multi-layer wrap according to  claim 19 , wherein the cling films are pre-stretched and further stretching of the wrap is limited by the stretching properties of the ribs.
