Reinforced fiberboard bulk container

Abstract

A reinforced fiberboard bulk materials container is provided that has low-fiber content and is humidity resistant. According to one embodiment, a fiberboard bulk materials container includes a plurality of fiberboard sidewalls forming a storage cavity and having a compression strength of 4 to 5 times the combined weight of cartons expected to be stacked above the bulk materials container, and a moisture-resistant polymer film wrapped around the outside of the sidewalls. The polymer film may substantially cover the sidewalls and extend from the top of the container to the bottom of the container along the sidewalls. A method for forming the bulk materials container includes stretch-wrapping the polymer film around the container sidewalls.

1 . A method for forming a corrugated fiberboard bulk materials container comprising:
 forming a fiberboard bulk materials carton in an open configuration, the carton having a plurality of sidewalls and a bottom together forming a storage space;   filling the storage space with dry-flowable bulk materials;   closing the carton; and   wrapping a moisture-resistant polymer film around the outside of the sidewalls to substantially cover the sidewalls extending from the top to the bottom.   
   
   
       2 . The method of  claim 1 , wherein the step of wrapping includes stretch-wrapping the moisture-resistant polymer film around the outside of the sidewalls. 
   
   
       3 . The method of  claim 2 , wherein the step of wrapping includes pre-stretching the moisture-resistant polymer film 200% to 300%. 
   
   
       4 . The method of  claim 3 , wherein the step of wrapping includes pre-stretching the moisture-resistant polymer film 250%. 
   
   
       5 . The method of  claim 2 , wherein the step of wrapping includes wrapping the film with a wrap tension of 2.5 to 7 pounds per foot of polymer film wrap width. 
   
   
       6 . The method of  claim 5 , wherein the step of wrapping includes wrapping the film with a wrap tension of 4 to 5 pounds per foot of polymer film wrap width. 
   
   
       7 . The method of  claim 1 , wherein the step of wrapping includes shrink-wrapping the moisture-resistant polymer film around the outside of the sidewalls.
