Process for heat shrinking a film wrapped bundle or article

Abstract

A process for heat shrinking a falm wrapped bundle or article that includes receiving the handle strip film and the wrapping film in either or both a static unit and a laser unit configured to emit amplified light, bonding the handle strip to the wrapping film by passing the handle strip film and the wrapping film in an overlapping relationship through the static unit and/or a laser unit, receiving the bonded handle strip and wrapping film directly to a perforation module that includes at least one of a handle rotary perforator and/or a laser perforator unit configured to emit amplified light and providing openings in the wrapping film adjacent the handle strip, film wrapping the bundle having the bonded strip over the bundle, and heat shrinking the film wrapped article causing the strip to seal to the film wrapped article.

What is claimed is: 
     
         1 . A process for heat shrinking a film wrapped bundle or an article having a handle strip film bonded to the inside of a wrapping film made from a material that seals to the wrapping film during the heat shrinking and comprising the steps of:
 receiving the handle strip film and the wrapping film in at least one of a static unit and a laser unit configured to emit amplified light;   bonding the handle strip to the wrapping film by passing the handle strip film and the wrapping film in an overlapping relationship through the at least one of a static unit and a laser unit;   receiving the bonded handle strip and wrapping film directly to a perforation module that includes at least one of a handle rotary perforator and/or a laser perforator unit configured to emit amplified light and providing openings in the wrapping film adjacent the handle strip that would allow one to grip over the handle;   film wrapping the bundle having the bonded strip over the bundle so that the strip is enclosed by the wrapping film; and   heat shrinking the film wrapped article causing the strip to seal to the film wrapped article.   
     
     
         2 . The process according to  claim 1 , further comprising:
 bonding the handle strip to the wrapping film by passing the handle strip film and the wrapping film in an overlapping relationship through the laser unit; and   receiving the bonded handle strip and wrapping film directly to the laser perforator unit that provides openings.   
     
     
         3 . The process according to  claim 1 , further comprising:
 electrostatically bonding the handle strip to the wrapping film with the static unit that includes a ground strap or bar and having a static probe receiving current and housed in an open-ended insulator sleeve, wherein the ground strap or bar are configured in a directly overlapping configuration.   
     
     
         4 . The process according to  claim 3 , further comprising:
 overlapping a strip bonded wrapping film during film wrapping the article whereby the strip is sandwiched between two layers of wrapping film so that heat shrinking seals the strip to both layers of film.   
     
     
         5 . The process according to  claim 4 , wherein the strip bonded film is perforated to provide a predetermined length of film for wrapping the article. 
     
     
         6 . The process according to  claim 1 , wherein the wrapping film and strip are made of the same material and are heat shrinkable. 
     
     
         7 . The process according to  claim 1 , wherein a flap of the strip bonded wrapping film is pushed on a conveyor. 
     
     
         8 . The process according to  claim 1 , further comprising:
 forming a vertical curtain by joining a strip bonded wrapping film with a wrapping film.   
     
     
         9 . The process according to  claim 8 , further comprising:
 pushing a bundle through the vertical curtain and cutting the film with a hot sealing blade that joins the cut films to form the vertical curtain.   
     
     
         10 . The process according to  claim 1 , whereing the heat shrinking seals at least 80% of the film handle to the wrapping film. 
     
     
         11 . The process according to  claim 3 , wherein the static probe receives 20 KV@150 uA direct current from a power unit, further comprising:
 electrostatically bonding the handle strip to the wrapping film by applying 20 KV@150 uA current to either the handle strip film or the wrapping film.   
     
     
         12 . The process according to  claim 3 , further comprising:
 receiving the handle strip film and the wrapping film in the static unit on a heat shrinking film wrapping machine, wherein the ground strap or bar is bonded to a frame of the heat shrinking film wrapping machine.
