Corrugated shipping boxes / JETDIELINE

Divider insert

Divider insert made from longitudinal and transverse strips with interlocking slots extending halfway down their height. All strips lie on a shared sheet and remain joined by holding nicks until separated.

How the shape is constructed

Partition made from longitudinal and transverse strips with interlocking slots extending halfway down their height, arranged without waste on one sheet and joined by separation lines with holding nicks; divides a box into length × width cells.

How it is assembled

Separate the strips along the separation lines. Turn over the transverse strips (slots downwards) and slot them over the longitudinal strips until the slot bottoms meet; place the partition in the box.

Material and grain direction

Flutes vertical in the strips (parallel to strip height): the strips bear load upright and do not buckle (check with the test printer).

Test fit, folding and closure on a sample made from the intended material. Confirm material thickness, grain direction and production steps with your printer.

What to consider for this construction

Cells along the length

Number of cells along the box length; there is one fewer transverse strip.

Cells along the width

Number of cells along the box width; there is one fewer longitudinal strip.

Strip height

Strip height as a proportion of box height.

Clearance at strip ends

Clearance between each strip end and the box wall.

Interlocking slot width

Width of the interlocking slots; at least the material thickness, and at the die at least the machine's minimum slot width.

Frequently asked questions

What does three by two cells mean?

cellsLength = 3 divides the box length into three cells; cellsWidth = 2 divides the width into two. This requires two transverse strips and one longitudinal strip. The parameters count cells, not strips. Check the clear cell size with the product and actual material thickness.

Why is the dieline taller than the insert?

The dieline shows all strips stacked on a shared sheet. Strip height belongs to each individual strip; sheet height adds them together. After separation, the strips are slotted together. The sheet's bounding dimensions therefore do not describe the assembled partition and must not be used as the box's inside dimensions.

Why are transverse strips turned over?

The interlocking slots extend halfway down the height. The transverse strips are placed over the longitudinal strips with their slots facing downwards until the slot bottoms meet. This interlocks the two directions. Check fit at the chosen slot width and fully separate the strips before assembly.
