Corrugated Box
Full Overlap (FOL)
The Full Overlap box looks similar to a Regular Slotted Container but with one critical difference: the outer flaps extend the full width of the box, overlapping almost completely when closed. This creates two layers of corrugated board on both the top and bottom panels. The flaps stop about one inch short of full overlap to prevent buckling when sealed.
FOL boxes are the go-to choice when you need extra compression strength for heavy, fragile, or high-value products.
