Abstract
A method of forming a shipping container includes mixing paper fibers with a binder fiber to form a mixture; disposing the mixture onto a surface to form a layer of the mixture; applying heat to form a paper fiber batt from the mixture having a fixed width and fixed length; and inserting the paper fiber batt within an interior of a corrugated box.
Claims10
A method of forming a shipping container, the method comprising:
- mixing paper fibers with about 0.5% to 25% by weight meltable PE/PP bi-component binder fiber to form a mixture, the binder fibers being of a length of less than about 24 millimeters;
- disposing the mixture onto a surface to form a layer of the mixture, the mixture having a density of 1300 to 1600 grams per square meter;
- applying heat to form a paper fiber batt from the mixture having a fixed width and fixed length;
- forming a shipping container from a paper medium, the shipping container defining an interior;
- securing a paper layer to the paper fiber batt;
- and
- surrounding the interior of the shipping container with the paper fiber batt,
- wherein subjecting the shipping container to a repulpability test produces a fiber yield of greater than 85%.
