ABOUT M & M BOX PARTITIONS CO.

  • All partitions are custom made without die charges to our customers.
  • Partitions are sets of fiberboard or corrugated strips which are cut, slotted and assembled to form a number of cells.
  • The number of cells equals the arrangement: 4 x 3: 12 cells, 10 x 5: 50 cells.
  • The cell size is measured from the center of one slot to the center of the next slot.
  • The cell size for a fiberboard partition is the part size plus 1/16″ (length + width)
    The cell size for a corrugated partition is the part size plus 3/16″ (length + width)
    The cell size height typically equals the height of the part being packaged.
  • Air cells are end cells which do not hold product.  They are usually smaller than the cell size and used primarily to form a protective cushion between the inner wall of a carton and the part being packaged.
  • Air cells can also be used to take up space between a cell and a stock box or a carton in current use.
