Two-Compartment Carton Insert

It is a friction-fit design. The operator folds the panels into a spiral and slides it into the outer carton, which holds the shape together without adhesive.

Folding an unglued spiral and holding it while inserting it into a box is difficult for automated cartoning equipment. It is usually packed by hand.

Without an outer carton to constrain it, the folded board will naturally uncoil and lose its shape. It must be used as an internal component.

The inner panels must be slightly smaller than the outer panels to fold inside them. If you switch to a thicker board without updating the template, the central divider will bow and the insert will not fit properly.

It prevents two items from striking each other and adds vertical strength to the outer box, but it does not provide cushioning on its own. For heavy or highly fragile goods, corrugated board or additional void fill may be needed.

It is often left plain to save costs. If you do print it, keep in mind that the folding sequence exposes different sides of the flat sheet in each compartment.

The paperboard grain must run parallel to the six crease lines. Incorrect grain direction will cause the folds to fight the outer carton, leading to a bowed divider and a poor fit.

This specific template creates two equal compartments. If you need uneven sections for a main product and a smaller accessory, a different template is used to shift the central wall.
