About this product

This interlocking corrugated partition creates individual cells inside an outer shipping box, preventing fragile items like bottles, jars, or industrial components from colliding during transit.

Delivered flat as separate slotted sheets, the dividers slide together to form a rigid grid that also adds vertical stacking strength to the master carton.

Common uses

Glass bottle shipping
Industrial component kitting
Cosmetics assortments

Practical Uses for Corrugated Partitions

Glass and Fragile Liquid Transport

Separates bottles and jars, preventing glass-to-glass contact and absorbing lateral impacts when packed inside a sturdy outer box.

Industrial Component Kitting

Organizes multiple metal or machined parts in a single shipper, preventing scratching and making inventory counts easier upon arrival.

Cosmetics and Personal Care Assortments

Keeps small bottles, tubes, and delicate containers upright and separated, ensuring labels and caps remain undamaged during transit.

Electronics and Device Separation

Prevents physical contact between bulk packed electronic components, reducing the risk of static friction or physical damage before final assembly.

Common Packing Environments

Fulfillment and Kitting Centers

Because the grid requires manual assembly, it fits well in fulfillment operations where packers build the partition at the bench before loading a multi-item order.

Beverage and Spirits Distribution

Useful for shipping multiple bottles in a single master carton, where the partition provides both separation and additional top-to-bottom crush resistance.

Automotive and Hardware Supply

Helps organize heavy, scratch-sensitive parts for bulk shipping, keeping inventory neat and preventing metal-on-metal damage.

When to Consider Different Inserts

High-Speed Automated Packing

Standard linear folder-gluers do not assemble intersecting grids. If manual assembly is too slow for the production volume, a die-cut insert or a tray formed by automated erectors may be worth comparing.

Single-Item Protection

If the box only holds one item, a roll-end tray with a custom die-cut cavity or a simple scored pad often provides better presentation and faster loading.

Key Decisions for Partition Fit

Board Thickness and Slot Width

The width of the interlocking slots must exactly match the board thickness. Changing board grades later requires design adjustments to prevent the board from tearing or fitting too loosely during assembly.

Cell Size and Clearance

Cells must be sized slightly larger than the maximum product diameter to allow easy loading, while the overall assembled grid must fit easily into the chosen outer box without crushing the perimeter.

Assembly Labor

Partitions are shipped flat. Packers must manually align and press the slotted length and width pieces together before dropping the completed grid into the box.

Outer Box Compatibility

The partition is not a standalone package. The exact internal dimensions of the master carton must be known to ensure the assembled grid fits securely without bowing.

Slot and Edge Profile Adjustments

Edge and Slot Profiles

The entry points of the slots can be angular, chamfered, or rounded. Rounded profiles help guide the pieces together, which can speed up manual assembly, though they may require flatbed die-cutting rather than simple straight cuts.

Cell Count and Grid Layout

The number of length and width dividers can be adjusted to create the exact grid needed for the product count, changing the overall footprint and the number of individual cells.

Flute Direction and Stacking Strength

Orienting the corrugated flutes vertically along the height of the dividers maximizes the top-to-bottom crush resistance added to the master carton.

Packing details

Vertical Stacking Strength

When fully seated, the top and bottom edges of the dividers sit flush. The intersecting walls bear top-to-bottom load, increasing the crush resistance of the master carton.

Additional notes

Slot shapes and cutting methods

Simple straight slots are straightforward to cut, while rounded or chamfered entry slots require flatbed die-cutting.

FAQs

Do these partitions come pre-assembled?

They are usually delivered flat to save shipping space. Packers manually assemble them by sliding the slotted pieces together at the packing station.

Are these suitable for automated packing lines?

Standard linear folder-gluers do not assemble intersecting grids. Unless the facility uses specialized partition machinery, this is usually a manual assembly step.

Can the cell count be changed?

Yes, the number of length and width dividers can be adjusted to create the exact grid needed for your product count.

Will this work with any outer box?

It can be sized to fit most slotted containers, but you must provide the exact internal dimensions of your chosen outer box to ensure the assembled grid fits without crushing.

What happens if I change the board thickness later?

The slot width is strictly tied to the board thickness. If you switch to a thicker board without adjusting the design, the slots will tear during assembly. A thinner board will result in a loose, wobbly grid.

Do I need tape or glue to hold the grid together?

No. The partition relies entirely on the mechanical friction fit of the intersecting slots.

How much clearance should I leave around my product?

Cells should be sized slightly larger than the maximum product diameter to allow easy loading and removal without the product rattling during transit.

Can the slot entry shapes be modified to speed up assembly?

Yes, rounded or chamfered slots can help guide the intersecting pieces together, which can make manual assembly faster at the packing bench.
