Abstract
A method of manufacturing a container for the temporary storage of foods is disclosed. The container includes a corrugated medium having a single backer paper thus creating an exposed corrugated surface on a side opposite the backer. The food container is formed such that the exposed corrugation is located towards an interior surface of the container. The method of manufacture involves fabrication of a single-face sheet of corrugated material to which is affixed a tape liner along opposed side edges of the sheet. A wider tape is affixed to the sheet intermediate the lateral edge tapes. The sheet is then cut along a longitudinal midline of the intermediate tape and also across the sheet to form discrete blanks. The blanks are substantially single-face corrugated material but have double-face corrugated material along the lateral edges where the tape was applied. Thereafter, the blank may be further cut, scored and folded to form containers having a single-face,bottom panel and double-face side walls.
