## Abstract

A method for forming a heat-reflective blank includes laminating at least one thermal film sheet at a predetermined position on a first linerboard sheet such that a laminated sheet is formed, and feeding the laminated sheet into a corrugating machine. The method further includes coupling the laminated sheet to a corrugated medium sheet and a second linerboard sheet such that a corrugated sheet is formed. The corrugated medium sheet is between the first linerboard sheet and the second linerboard sheet and the thermal film sheet is positioned on an outer surface of the corrugated sheet.

## Claims

### Claim 1

A method for forming a heat-reflective blank comprising:
laminating at least one thermal film sheet at a predetermined position on a first linerboard sheet such that a laminated sheet is formed;
feeding the laminated sheet into a corrugating machine; and
coupling the laminated sheet to a corrugated medium sheet and a second linerboard sheet such that a corrugated sheet is formed, wherein the corrugated medium sheet is between the first linerboard sheet and the second linerboard sheet and the thermal film sheet is positioned on an outer surface of the corrugated sheet.

### Claim 2 (depends on 1)

The method in accordance with claim 1 further comprising cutting the corrugated sheet into a plurality of heat-reflective blanks.

### Claim 3 (depends on 1)

The method in accordance with claim 1 further comprising positioning the at least one thermal film sheet on the first linerboard sheet such that a width of the first linerboard sheet is greater than a width of the at least one thermal film sheet.

### Claim 4 (depends on 3)

The method in accordance with claim 3, wherein the at least one thermal film sheet is positioned on a first edge of the first linerboard sheet.

### Claim 5 (depends on 1)

The method in accordance with claim 1 further comprising continuously laminating a first thermal film sheet at a first predetermined position on the first linerboard sheet and a second thermal film sheet at a second predetermined position on the first linerboard sheet, wherein the first thermal film sheet is adjacent second thermal film sheet.

### Claim 6 (depends on 1)

The method in accordance with claim 1 further comprising positioning the at least one thermal film sheet on the first linerboard sheet such that a plurality of thermal film pieces are spaced at a predetermined distance along a length of the first linerboard sheet.

### Claim 7 (depends on 1)

The method in accordance with claim 1 further comprising converting the heat-reflective blanks to heat-reflective boxes.

### Claim 8 (depends on 1)

The method in accordance with claim 1 further comprising continuously feeding the laminated sheet into the corrugating machine such that the corrugated sheet is formed through a continuous process.
