Interlocking Grid Partition

Conventional linear folder-gluers cannot handle intersecting slotted webs. Automated insertion requires specialized capital equipment and pre-assembled grids from the converter. Most operations insert them by hand.

It prevents items from colliding with each other and adds substantial vertical stacking strength. However, because the outer cells touch the master box walls, perimeter items will absorb direct side impacts.

No. The slot widths are cut exactly to the board's thickness. If you switch to a thicker board, the strips will bind and crush during assembly. If you switch to a thinner board, the grid will be loose and floppy.

Straight slots can be produced rapidly on dedicated partition slotters. Angled entry points require a flatbed or rotary die-cutter, which changes the production route and setup process.

They can be shipped as flat, loose strips to maximize pallet density, or as pre-assembled, diagonally collapsed grids that take up slightly more space but reduce packing labor.

With standard corrugated board, cell size is limited by the flute thickness and the slotting equipment. For tight grids, such as 8x8mm cells, solid board is typically required.

Yes. When cut from heavy-duty double-wall board, the rigid intersecting walls can handle multiple trips between facilities, making it useful for moving industrial parts or sub-assemblies.

Operators orient the longitudinal webs with their slots facing up, and the transverse webs with their slots facing down, then slide them together perpendicularly until the slots lock at the midpoint.
