Overview
Corrugated inserts and dividers organise the space inside a box. They can separate repeated units, create cells around bottles or components, or fold into supports that stop a product moving without turning the whole pack into a mixed-material assembly.
Fit depends on the relationship between the insert, the product and the outer case, so the three are developed together. Cavity positions, loading sequence, contact points and product movement are reviewed on a fully loaded sample. Any transport-performance requirement then has to be agreed and assessed against the intended journey rather than inferred from material alone.
Two constructions cover most needs. Slotted partitions are strips of corrugated board, each cut halfway through at the crossing points, that slide into one another to form a grid of cells; they are supplied flat for assembly or ready-assembled. Folded fitments are a single die-cut piece creased into platforms, collars or raised cradles that brace against the case walls and hold an item at a set height or position. In both, flute direction matters: a partition stands stiffer with its flutes running vertically, so the board orientation is fixed on the dieline.
What to decide for this format
Separation & Loading Sequence
Define which items must not touch, how operators load them and whether the divider arrives pre-assembled or flat.
Outer Case Relationship
Develop the insert against the actual case dimensions so its folds, cells and supports stay located after packing.
Corrugated Fitment or Foam Insert
Foam cushions impact and grips irregular shapes closely, but it adds a second material and takes up storage space before packing. A corrugated fitment ships flat and keeps the pack in one material family, but it locates and separates rather than cushions; choose it when position and separation are the main job.
Printing & Finishes
Die Cutting & Creasing
Cells, partitions and folded supports are cut and creased to the approved insert layout.

Design & artwork
From an artwork check, through a dimensioned dieline and print-ready files, to a full concept package across a range — done by the factory that will make it.
Applications
Repeated Units & Multipacks
Cells and partitions used to separate repeated products inside a shared case.
Bottle & Component Separation
Folded corrugated fitments considered where locating and separation are the primary tasks.
E-Commerce Sets
Product-specific layouts developed with the mailer and checked on the complete loaded sample.
How it is made
Product, case & journey review
Product geometry, contact limits, loading sequence, outer-case dimensions and intended journey are reviewed together.
Insert layout
Cells, folds and support points are developed against the product and finished outer case.
Sampling
A cut and folded insert is loaded with the actual products wherever possible so fit and movement can be checked.
Die cutting & forming
The approved layout is die cut and creased, then folded or assembled to the specified supply format.
Inspection & packing
Dimensions, folds and count are checked against the approved sample before packing with the outer-case programme.
Frequently asked questions
Can corrugated dividers replace foam inserts?
They may be suitable when separation and location are the main tasks. A loaded sample checks fit and movement; if impact or transit performance is required, the acceptance method and journey conditions need to be defined separately before the material is approved.
Should the insert be designed separately from the box?
No. The insert consumes internal space and transfers load into the case, while the case controls where the fitment can bear. Developing both together avoids a divider that fits on screen but moves or bows after packing.
What do you need to quote corrugated inserts?
The product or its exact dimensions, the outer case size or a request to develop the case with the insert, how many items go in each case and in what arrangement, which surfaces must not touch, whether you want the inserts flat or pre-assembled, and the delivery country (for the EU or the UK, also whether you want DDP or DAP).
Partition grid or folded fitment: which should we use?
A partition grid suits many similar items that only need separating, and it is quick to adapt to a new cell count. A folded fitment suits one product, or a set, that must sit at a fixed height or position, but it needs its own cutting die and usually more sampling rounds. The loaded sample shows which one controls movement better in your case.
